SAFETY AND PREPARATION FOR USE

**********WARNING **********

This unit contains hazardous high voltages. Please make certain that the high voltage is completely discharged before removing the high voltage cable. High voltage cables can store charge if they are disconnected from the supply while the high voltage is on. The charge on the cable can cause injury or damage even after the cable is disconnected from the unit.

Do not change the high voltage polarity unless the power is off.

***********CAUTION **********

This instrument may be damaged if operated with the LINE VOLTAGESELECTOR set for the wrong AC line voltage or if the wrong fuse is installed.

Line Voltage Section

The PS300 series operates from 100, 120, 220 or 240 Volts nominal AC power source with a line frequency of 50 or 60 Hz. Before connecting the power cord to a power source, verify that the LINE VOLTAGE SELECTOR card, located in the rear panel fuse holder, is set so the correct AC input voltage is visible.

Conversion to other AC input voltages requires a change in the fuse holder voltage card position

and fuse value. Disconnect the power cord, open the fuse holder cover door, and rotate the fuse-pull lever to remove the fuse. Remove the small printed circuit board. Select the operating voltage by orienting the printed circuit board. Press the circuit board firmly into its slot, so the desired voltage is visible. Rotate the fuse-pull lever back into its normal position. Insert the correct fuse into the fuse holder.

Line Fuse

Verify that the correct line fuse is installed before connecting the line cord. For 100 V / 120 V, use a 1 Amp fuse and for 220 V / 240 V, use a 1/2 Amp fuse.

Line Cord

The PS300 series use a detachable, three-wire power cord for connection to the power source and to a protective ground. The exposed metal parts of the instrument are connected to the outlet ground which provides protection against electrical shock. Always use an outlet which has a properly connected protective ground.

Connection to Other Instruments

The back panel BNC shields are connected to the chassis ground and the AC power source ground via the power cord. Do not apply any voltage to the shield. The high voltage SHV connector is also connected to the chassis ground and CANNOT be floated away from ground.

INSTRUMENT OVERVIEW

Front Panel Su m mary

Power Button

The PS300 series are turned on by depressing the POWER button. The unit always powers up with the high voltage OFF. All instrument settings are stored in nonvolatile memory and are saved when power is turned off. The model number (310, 325, or 350), firmware version, and serial number are displayed when power is turned on. If an error appears on power on, then the stored settings were lost and the default settings are used. If the default settings are desired, hold down the CLR (clear) key while turning on the power.

High Voltage Enable Switch

This is a three position switch that performs several functions. In the down position, the high voltage is off and all trips are cleared. In this position the high voltage is locked OFF and cannot be turned on by computer control. The up position is momentary and turns on the high voltage for manual or rear panel analog control. In the middle position the high voltage is enabled (but not necessarily on) and can be turned on by computer. The large red LED above the switch indicates that the high voltage is on; the yellow LED below it indicates a trip has occurred.

LED Displays

The two large displays show output voltage and current to four significant places. Polarity is displayed on the left of the voltage display. The smaller center display shows the value of the parameter that is being entered or adjusted. That parameter is indicated by the row of LEDs directly below the center display.

Select, Enter, and Clear

The SELECT key is used to choose which parameter is being displayed in the center display. The ENTER key enters the parameter shown in the center display. The clear (CLR) key erases the value in the middle display and recalls the last value that was entered. To adjust a value, the SELECT key is pressed until the appropriate LED is lit. When the value is being changed, that LED will flash to indicate that the value in the center display is not the current unit setting. If an incorrect value is entered, press CLR (clear) to start over. When the desired value is in the center display, pressing the ENTER key updates the unit's actual setting and stops the LED's flashing.

Numeric and Cursor Keys

Other Keys

All parameters may be adjusted using the cursor or numeric keys. When using the cursors, the digit being adjusted in the center display will flash. The UP and DOWN keys increment and decrement the digit. The LEFT and RIGHT keys select the flashing digit. When using direct numerical entry, simply press the number and decimal point keys until the desired value appears on the center display. Note that the current is specified in mA.

Instrument Status

Three LED's indicate the instrument's status. The LIMIT LED is on when the unit is in current limit. REM is on when the front panel is locked out. SRQ is on when a GPIB service request is pending.

RESET sets the reset mode to either AUTO or MAN (manual).

GPIB displays the GPIB address in the center display so it can be adjusted. It is also the LOCAL key when the unit is in the remote mode.

Store and Recall

STO (store) and RCL (recall) allow up to 9 complete instrument settings to be saved in nonvolatile memory. RCL 0 recalls the default settings.

Rear Panel Summary

Power Entry Module

The power entry module is used to fuse the line, select the line voltage, and block high frequency noise from entering or exiting the unit. Refer to the first page of the manual for instructions on selecting the correct line voltage and fuse.

High Voltage Output Connector WARNING: This unit contains hazardous

voltages. Please make certain that the high voltage is completely discharged before removing or connecting the high voltage cable. High voltage cables can store charge if they are disconnected from the supply while high voltage is present which can cause injury or damage the unit.

The high voltage output connector is an SHV male connector (Kings type 1704-1). Please make certain that the high voltage is completely discharged before changing the cable.

A 10 feet SHV-SHV or SHV-MHV cable is available from SRS.

High Voltage Polarity Selector WARNING: The unit must be turned off and the

high voltage should be completely discharged before reversing the polarity. Failure to do this can cause injury or damage the unit.

Polarity is indicated by the screwdriver slot on the polarity switch as well as on the front panel's voltage display. To reverse the polarity, turn the unit off and allow the high voltage to completely discharge. Then turn the polarity switch with a large flathead screwdriver (clockwise for + to - and counterclockwise for - to + ).

Analog Outputs

The two BNC's provide voltage and current monitor signals, or an external voltage set and current monitor. When the voltage select switch is in the MON (monitor) position, both are 0 to +10 Volt outputs corresponding to 0 to full scale. When the voltage select switch is in the SET position, the current signal acts the same, but the voltage BNC is an input, setting the the high voltage over the same scale. When the switch is in the SET position, the REAR LED on the front panel is lit, indicating that the high voltage is under analog control and cannot be adjusted from the keypad. All signals are positive voltages, independent of output voltage polarity.

IEEE-488 Std Port (optional)

The 24 pin IEEE-488 (GPIB) connector allows computer control of PS300 series supplies. The address is set from the front panel using the GPIB key.

GUIDE TO OPERATION

Setting Output Voltage

The voltage set can be changed with the high voltage on or off.

To set the high voltage output, press the SELECT key until the VOLTAGE SET LED is lit. The present value of the set voltage will be displayed in the center window. To change the value, enter the desired voltage by either the numeric or cursor keys. After the new value has been entered into the center display, press ENTER to update the output voltage. The VOLTAGE SET LED will flash until ENTER or CLR is pressed to remind you that the displayed value is not the actual programmed value. If an 'Err2' message appears (illegal parameter entered), check the voltage limit to see that it is greater than or equal to the desired set voltage. Use the CLR key to clear any error message.

If the REAR LED is lit, the high voltage is programmed from the analog set input on the rear panel. In this mode, when the center display is showing VOLTAGE SET, the display is the present programmed value of the high voltage and cannot be adjusted from the front panel.

Setting Voltage Limit

The voltage limit is a protection feature to prevent the output voltage from being set too high or overshooting because of dramatic load changes. The output voltage cannot be set higher than the voltage limit. In addition, if the output ever exceeds the limit by more than 10% of full scale, the unit trips and the high voltage is disabled. If this occurs, a 'VTRP'(voltage trip) message appears in the middle display.

After a trip it is not necessary to clear the trip before turning the high voltage back on. If it is necessary to change a parameter before turning the high voltage back on, pressing CLR or putting the high voltage switch in the off position will clear the trip.

To set the voltage limit, press the SELECT key until the VOLTAGE LIMIT LED is lit. The present value of the voltage limit is displayed in the center window. Change it with either the numeric or cursor keys and press ENTER to update the actual limit value. If an 'Err2' message appears (illegal

parameter entered), check to see that the output voltage is less than or equal to the voltage limit.

Setting Current Limit

Current limiting varies the output voltage to limit the output current to less than or equal to the programmed current limit value. When the unit is current limited, the LIMIT LED is lit.

The current limit is set in the same fashion as the voltage limit, by SELECTing the present value on the center window, changing it and then ENTERing the new value.

Setting Current Trip

The current trip shuts off the high voltage when the output current exceeds the trip value. The current trip value is set in the same fashion as the voltage and current limits. After a current trip occurs, the 'ITRP' (current trip) message will appear in the middle display. Current trips are cleared in the same fashion as voltage trips.

Primary Trip

A PTRP (primary trip) message will occur if the current through the primary side of the high voltage transformer and the switching MOSFET's exceeds about 5.3 Amps. This feature is included to protect the transformer and FET's. The trip level is not user programmable and may be cleared in the same manner as the voltage and current trips. If repeated PTRP's occur, see the troubleshooting section.

Reset Mode

The reset mode determines how the unit responds after a voltage or current trip.

MAN (manual) Mode: The high voltage remains

off after a trip and requires that the operator turn it back on.

AUTO (automatic) Mode: The unit waits until

the output voltage has fallen to 1/50 of its full scale value and then turns the high voltage back on. This is useful when dealing with loads that occasionally short circuit but recover after removing the high voltage.

Store and Recall

STO (store) and RCL (recall) allow up to 9 complete instrument setups to be saved. To store a setup, press the STO key, followed by a number (1-

9) and then the ENTER key. To recall a setup, press the RCL key, followed by a number (0-9) and then the ENTER key. RCL 0 returns the setup to the factory default. Whenever a setup is recalled, the high voltage is turned off for safety. If an 'Err3' (recall error) occurs, then that stored setup was lost due to a memory error and must be re-entered.

Error Messages

The following error messages may appear in the center display. The CLR key clears the errors.

and does not allow the rear panel voltage to set the output above the voltage limit. If the rear panel voltage is too high, the output voltage will stop at the limit voltage.

Voltage Monitor/Set: When the Analog

Programming switch is in the MONITOR position, the VOLTAGE BNC is a monitor output providing 0 to +10 Volts for 0 to full scale output regardless of polarity. When the switch is in the SET position, the BNC becomes an input over the same range. An input of 0 to +10 Volts will program the high voltage from 0 to full scale, regardless of polarity.

Current Monitor: This provides 0 to +10 Volts

out for 0 to full scale output regardless of the output polarity.

Err1 Memory Error

Power on memory error of the unit's last setup. Default setup is recalled.

Err2 Illegal Parameter Entered.

Err3 Stored Value Recall Error

The stored setup (from STO and RCL) was lost.

Err4 Illegal Storage Address

STO 0 is reserved for default settings.

Err5 No GPIB Interface The unit does

not have the GPIB option so the GPIB address cannot be set.

Err6 Syntax error over GPIB.

Err7 Illegal parameter entered over GPIB.

Parameter entered is out of range.

Err 8 GPIB Output queue full.

Analog Programming and Monitor

The rear panel voltage select switch determines whether the output voltage is set from the front panel or from the rear panel voltage input. If the switch is in the MON (monitor) position, the front panel will set the voltage. If the switch is in the SET position, the rear panel voltage will set the output voltage. When the switch is in the SET position, the REAR (rear panel) LED is lit and the output voltage being set by the rear panel is displayed in the middle display when it is showing VOLTAGE SET. The voltage limit is still active

If the switch position is changed while the high voltage is on, the unit will shut the high voltage off.

Default Setup

The factory default setup can be recalled by pressing the CLR key while turning the unit on or recalling setup 0 (RCL 0). The default setup is also recalled after a power on memory error (ERR 1).

The default setups are shown below.

GUIDE TO PROGRAMMING

Remote Programming

The PS300 series High Voltage Power Supplies may be remotely programmed via the GPIB (IEEE-

488) interface. Any computer supporting this interface may be used to program the PS300.

The PS300 supports the IEEE-488.1 (1978) interface standard. Additionally, it also supports the required common commands of the IEEE-488.2 (1987) Standard. Before attempting to communicate with the PS300 over the GPIB interface, the PS300's device address must be set. The address is set from the front panel by pressing the GPIB key and using the up and down arrow keys to set the address to any number between 0 and 30. Pressing the ENTER key then sets the selection.

Command Syntax

Communications with the PS300 use ASCII characters. Commands may be in either UPPER or lower case and may contain any number of embedded space characters.

A command to the PS300 consists of a four character command mnemonic, arguments if necessary, and a command terminator. The terminator is a linefeed <lf> or EOI. No command processing occurs until a command terminator is received. Command mnemonics beginning with an asterisk "*" are IEEE-488.2 (1987) defined common commands. Commands may require one or more parameters. Multiple parameters are separated by commas ",".

Multiple commands may be sent on one command line by separating them by semicolons ";". The difference between sending several commands on the same line and sending several independent commands is when a command line is parsed and executed, the entire line is executed before any other device action proceeds. This allows synchronization to be achieved using the synchronization commands.

There is no necessity to wait between commands. The PS300 has a 256 character input buffer and processes commands in the order received. If the buffer fills up, the PS300 will hold off handshaking on the GPIB. Similarly, the PS300 has a 256 character output buffer to store output until the host

computer is ready to receive it. If the output buffer fills up, it is cleared and an error reported.

The present value of a particular parameter may be determined by querying the PS300 for its value. A query is formed by appending a question mark "?" to the command mnemonic and omitting the desired parameter from the command. If multiple queries are sent on one command line (separated by semicolons, of course), the answers will be returned in a single response line with the individual responses separated by semicolons. The default response terminator that the PS300 sends with any answer to a query is a linefeed plus EOI. All commands return integer results except as noted in individual command descriptions.

Examples:

VSET1.0E3<lf> sets VSET to 1000 V VSET?<lf> queries the value of

VSET

*IDN? <lf> queries the device

identification (query, no parameters)

VSET100.0;VSET? <lf> sets voltage to 100 V

and queries the voltage

Detailed Command List

The four letter mnemonic in each command sequence specifies the command. The rest of the sequence consists of parameters. Multiple parameters are separated by commas. Commands that may be queried have a question mark ? in parentheses (?) after the mnemonic. Commands that may ONLY be queried have a ? after the mnemonic. Commands that MAY NOT be queried have no?.

Output Control Commands

HVOF

The HVOF command turns the high voltage OFF.

HVON

The HVON command turns the high voltage ON provided that the front panel high voltage switch is not in the OFF position. If the switch is in the OFF position, the high voltage is left off and an

execution error is reported. This command also automatically clears any voltage or current trips.

setting mode may only be changed by setting the rear panel switch.

IOUT?

The IOUT? query returns the actual output current. This is the same value as shown on the front panel meter. Note: As with the front panel meters, this value takes about a second to stabilize after a change in current.

VOUT?

The VOUT? query returns the actual output voltage. This is the same voltage as shown on the front panel meter. The value returned is a floating point value and includes the sign of the output voltage. Note: As with the front panel meters, this value takes about a second to stabilize after a change in voltage.

Setting Control Commands

*RCL i

The *RCL command recalls stored setting i. Setting 0 recalls the default settings. If the stored setting is corrupted, an error is returned.

*SAV i

The *SAV command stores the present setup as setting i. i may range from 1 to 9.

ILIM(?) x

TCLR

The TCLR command clears any voltage or current trips.

TMOD(?) i

The TMOD command sets the trip reset mode. The value i = 0 sets manual trip reset, while the value i = 1 sets the trip reset mode to auto.

VLIM(?) x

The VLIM command sets the value of the voltage limit to x where x is the value in Volts. The sign of value x MUST match the PS300's polarity setting. The VLIM? query returns the present VLIM setting. As with front panel control, the VLIM value must be greater than or equal to the VSET value or an execution error will be returned.

VSET(?) x

The VSET command sets the value of the voltage set to x if front panel control is enabled. If rear panel control is enabled, an error is returned. The value x is a number in the units of Volts and the sign of the number MUST match the PS300's polarity setting. The VSET? query returns the current VSET value. As with front panel control, the VSET value must be less than or equal to to VLIM value or an execution error will be returned.

The ILIM command sets the value of the current limit to x. The value x is a floating point value with the units of Amps (e.g. 1 mA = 1E-3). The ILIM? query returns the current limit setting.

ITRP(?) x

The ITRP command sets the value of the current trip to x. The value x is a floating point value with the units of Amps (e.g. 1 mA = 1E-3). The ITRP? query returns the current trip setting.

SMOD?

The SMOD? query returns the VSET setting mode. The value 0 means that the voltage value is controlled by the front panel setting, while the value 1 indicates that the output is controlled by the rear panel voltage control input. Note that the

Interface Control Command

*RST

The *RST common command resets the PS300 to its default configurations. It is the same as holding down "CLR " at power on.

*IDN?

The *IDN common query returns the PS300's device configuration. This string is in the format: StanfordResearchSystems,PS3XX,serial number, version number, where XX is the particular model number, "serial number" is the serial number of the particular unit, and "version number" is the 3 digit firmware version number.

Status Reporting Commands

*CLS

The *CLS common command clears all status registers

*ESE (?) j

The *ESE common command sets the standard status byte enable register. The parameter j is the decimal value that the enable register is to be set to.

*ESR? {j}

such as SRQ on power up to be produced if desired.

has occurred.

The *ESR common command reads the value of the standard status register. If the parameter j is present the value of bit j is returned. Reading this register will clear it. Reading bit j will clear bit j only.

*PSC (?) j

The *PSC common command sets the value of the power-on status clear bit. If j = 1, the power on status clear bit is set and all status registers and enable registers are cleared on power up. If j = 0, the bit is cleared and the status enable registers maintain their values at power down. This allows the production of a service request at power up, etc.

*SRE (?) j

The *SRE common command sets the value of the serial poll enable register. The parameter j is the decimal value that the register is to be set to.

*STB? {j}

The *STB? common query reads the value of the serial poll byte. If the parameter j is present the value of bit j is returned. Reading this register has no effect on its value. It is just the summary of the other status registers.

Status Reporting

2 itrip This indicates that a current trip

has occurred.

3 ilim This indicates that a current limit

condition has occurred.

4 MAV This indicates that the GPIB

output queue is non-empty.

5 ESB This indicates that an unmasked

bit in the standard status byte has been set.

6RQS/ SRQ BIT.

MSS

7 hvon This indicates that the high

voltage is on.

The PS300 will make a service request (SRQ) whenever one of these bits is set AND the corresponding bit in the serial poll enable register is set. Note that any status condition will produce only one SRQ even if it is never cleared. The vtrip, itrip and ilim bits are latched bits. They are set on the occurrence of the appropriate event and stay set until either the status byte is read or the *CLS command is sent. This allows one to detect if a trip condition has ever occurred. All of the other bits indicate the current states of their respective functions.

The PS300 reports on its status by means of two status bytes: the serial poll byte, and the standard status byte.

On power up, the PS300 may either clear all of its status enable registers or maintain them in the state they were in during power down. The action taken is set by the *PSC command and allows things

error or unrecognized command.

The following error messages will appear on the middle display if an error occurs due to a command sent over GPIB:

Err6 Syntax Error over GPIB.

The command had an error in syntax or was unrecognizable. A syntax error could be a misspelling of a command or forgetting to include a '-' when setting a negative value for the voltage or voltage limit. This error is the same as Command Error, bit 5 of the Standard Event Status Byte.

Err7 Illegal Parameter entered over GPIB.

A parameter was set out of range, or a command could not be completed because of an overload. This error is the same as Execution Err, bit 4 of the Standard Event Status Byte.

Err 8 GPIB Output Queue full.

The output queue overflowed and was cleared. This could be due to querying the unit repeatedly and not reading out all of the characters, or a problem at the recieving unit. This error is the same as Query Error, bit 2 of the Standard Event Status Byte.

PROGRAM EXAMPLES

This section lists example programs which use the GPIB port to control the PS300. All of the programs do the same thing, only the language is different. The programs set up the PS300 to ramp the output voltage from 0 to 1000 Volts while reading the output current.

Program Example 1: IBM PC, Microsoft BASIC, Via GPIB

This program requires the Capital Equipment Corporation GPIB card for the IBM PC. It has firmware in ROM to interface high level languages to the GPIB.

Subroutine calls in Microsoft BASIC are done to memory locations specified by the name of the subroutine. The address is relative to the segment address specified by the DEF SEG statement preceding the CALL.

In this program, the CEC card's ROM starts at C000H, the system controller's address is 21, and the PS300 is at GPIB address 23. Make sure the address in the unit is set correctly and that the HIGH VOLTAGE ENABLE switch is not OFF.

Program Example 2: IBM PC, Microsoft C V4.0, Via GPIB

This program requires the Capital Equipment Corporation GPIB card for the IBM PC. It has firmware in ROM to interface high level languages to the GPIB.

The header file MS-C488.H contains definitions of all of the CEC firmware routines which can be called from C. Note that the order of arguments in the calls are reversed from those used by BASIC.

To use these routines, the large model must be used. Compile with the /AL/Ze switch and link with GPIBL.OBJ (on the CEC disk).

/* Compile with >MSC program name/AL/Ze;

link with GPIB-L.OBJ (on CEC disk) include MS-C488.H

MS-C488.H defines all of the CEC firmware routines so that they can be called from a C program. Remember that the order of the arguments is REVERSED from the BASIC calls described in the manual.

Example program to ramp the PS300 output and read the current using Microsoft C v4.0 (large model) and the Capital Equipment Corp. GPIB interface card.

Set the PS300 for GPIB ADDR=23.

#include <ms-c488.h> #include <stdio.h>

char result[80];

Program Example 3: IBM PC, Microsoft C V4.0, Via GPIB

This program requires the National Instruments GPIB card for the IBM PC. It has firmware on board that interfaces it to high level languages.

To interface the PS300 to a PC with the National Instruments card, the interface card and drivers must be configured properly. The National Instruments card CANNOT be simply unpacked and put into your computer. The card must be configured with jumpers and switches to set the I/O address and interrupt levels. You must also run the program "IBCONF" to configure the resident GPIB driver for the card. Please refer to the National Instruments manual for additional information.

Once all the hardware and GPIB drivers are properly configured, use the IBIC program. This terminal emulation program allows you to send commands to the PS300 directly from your keyboard. If you cannot talk to the PS300 from IBIC, your programs will not run.

The header file decl.h must be included and the file should be linked with the appropriate cib*.obj.

Compile with >MSC program name/AL/Ze; Link with the appropriate cib*.obj (on the Nat'l Inst disk) Include decl.h.

Example program to set the PS325 to 1000 volts and read the current using Microsoft C v4.0 (large model) and the National instruments GPIB interface card.

#include <stdio.h> #include <stdlib.h> #include <decl.h>

main();

{ int i,status,ps300; float x; char data[40];

/* get device ID for power supply */

ps325 = ibfind("PS325") if (ps325<0)

{ printf ("Cannot find PS325; rerun IBCONF/n"); exit(0); }

/* reset ps300 */

ibwrt (ps300,"*RST",4);

/* turn on high voltage */

ibwrt (ps300,"HVON",4);

/* set voltage to 1000 volts */

ibwrt (ps300, "VSET1000",8);

/* read current */

ibwrt (ps300,"IOUT?",5);

ibrd (ps300,data,20);

/* print answer */

sscanf (data,"%f",&x);

printf ("Voltage = 1000 Current = %1f/n",x);

}

TROUBLESHOOTING

Always make certain that the power entry module is set for the correct line voltage and the correct fuse is installed. The selected line voltage can be seen through the window on the power entry module. Verify that the line cord is plugged all the way into the power entry module and the power button on the front panel is pressed in.

Power on Reset

If the instrument turns on with odd combinations of LEDs on, garbled displays, or is unresponsive to the keyboard, the memory contents may have been corrupted, causing the instrument to "hang". To remedy the situation, turn the unit off and hold down the CLR key while turning the power back on. This causes the unit to initialize the memory and load the default setup.

Stuck Keys

If the center display is filled with a particular number (like 4444), or one particular message (like Err2), and the keyboard is unresponsive, check to see if a key is stuck down. If so, gently flick the stuck key back to the center of its hole.

No High Voltage

3) Check the the REAR LED. If it is on, then the high voltage is being programmed by the analog set voltage input on the rear panel and not by the front panel. If so, make sure the rear panel switch is in the desired position.

Repeated Trips

Voltage Trips: This may occur if the load changes

too rapidly, causing the voltage to overshoot. Try raising the voltage limit.

Current Trips: Disconnect the load and see if the

unit still trips. If it works with no load, there may be a problem with the load. If it still trips, the unit may be damaged. Please contact the factory for further information.

Primary Trip: If repeated PTRP's occur, the

power supply may be damaged. Please contact the factory for further information.

Rear Panel Voltage Set

If the output voltage is not correct, check the REAR LED and rear panel switch to see that they are in the SET mode. Also check that the voltage limit is higher than the desired voltage.

Check to make sure that the HIGH VOLTAGE LED is on. If the HIGH VOLTAGE LED is OFF, check the following.

1) Make certain you hold down the high voltage key for at least half a second. It is designed to take a fairly long keypress to avoid having the high voltage turned on accidentally by bumping into the switch.

2) Check the voltage limit and current trip levels to see that they are not too low for your load.

If the HIGH VOLTAGE LED is ON but the output voltage is zero or lower than expected, check the following.

1) Check if the LIMIT LED is on. If so, the current limit value could be too low or the load could be drawing excessive current.

2) Make sure the voltage limit is as large or larger than the desired output voltage.

Front Panel Tes t

Hold down the ENTER key while turning on the unit to run the front panel test. After power is turned on, one segment of one numerical digit should be lit. By pressing the UP arrow key, step through all 8 segments of this digit and the following one. This verifies that all of the segment drivers are functional. On the next UP keypress, all segments and one of the single LED's should be lit. By repeatedly pressing the UP key, all of the single LED's can be turned on, one at a time. The keypad can then be tested by pressing each key and observing the key code on the display. The codes increase from top to bottom and left to right. After this test, turn the power off and restart the instrument.

Calibration

The calibration parameters are determined by a computer aided calibration procedure after burn-in at the factory. These values are stored in the permanent memory of each unit. Because of this there are no user adjustable components to calibrate.

CIRCUIT DESCRIPTION

Introduction

Schematics for the PS300 series supplies are shown on the following pages. They include the following: Voltage Control (page 1/11), Low voltage pre-regulator and high frequency inverter (page 2/11), Limits and Trip Circuitry (page 3/11), A/D and D/A (page 4/11), the Microprocessor (page 5/11), GPIB and Front Panel Control (page 6/11), Low Voltage Power Supplies (page 7/11), Front Panel (page 8/11), and the High Voltage Sections (page 9/11 through 11/11).

Most of the components are located on the main circuit board. The front panel and high voltage section are located on separate boards. In addition, the high voltage board is covered with an acrylic coating and enclosed in a protective box.

Voltage Control

Since the output is transformer coupled, only the magnitude can be set by the primary side control circuitry. The polarity must be set in the high voltage section by a multi-pole switch. However, the sensed voltage and current vary with polarity and must be converted to a unipolar signal before they can be used to control the output. To minimize the effects of noise, the sensed voltage and current are converted to a -8.26 to +8.26 V range (-8.26 V corresponding to 0 volts out, +8.26 to full scale). This allows 13 bits of resolution from the D/A over ±10 V with a relatively large bit size of 2.5 mV.

The sensed voltage, V SENSE (coming from a resistive divider in the high voltage section) is buffered by a high input impedance differential amplifier made up of U109A, U109B and U101D. This provides a 0 to +8.26 V signal. Next the polarity is set (for positive or negative output voltages) with a programmable low offset inverter (U102, U104A and U104B) and then scaled to ±8.26 V. Next, the voltage is compared to the programmed voltage with U101B. This signal is then frequency compensated (U108, U101C, and related R's and C's) to provide an error voltage, V ERR. D104 and D107 keep the large capacitors in the frequency compensation circuitry from saturating.

The sensed current is first amplified by U105 from 0 - 250 mV to 0 to +8.26 V. Next, the polarity is set by the programmable inverter of U104C,

(page 1/11)

U104D and U106. It is scaled to ±8.26 V by U107C. Then it is compared and frequency compensated at U107B, to provide I ERR.

D102 acts as a crossover between the two error signals to determine which one sets V DRIVE, the control for the output voltage. If I ERR is higher than V ERR (voltage control mode), then V ERR controls V DRIVE. However if I ERR is lower (supply is in current limit), it can pull down V DRIVE(through D102) to the appropriate level, since V ERR is isolated by R110.

Diodes D105 and D106 act to keep op amps U101C and U107B out of saturation during large load changes. This improves transient response.

Low Voltage Pre-Regulator and HIgh Frequency Inverter

High voltage is made with a high frequency DC to DC converter. It operates by driving the common tap of a step-up transformer used as an inverter, from 0 to 35 volts DC. This makes high voltage by a combination of transformation and voltage multiplication. Control is achieved by regulating the common tap.

Pre-Regulator

The common voltage is made by a combination step down pre-regulator followed by a programmable linear regulator. Q203, D203, L201 and C203 form the step down regulator and U205 is the linear regulator.

U206, an LM311 comparator, senses the voltage across U205. If it is less than 2.5 volts (determined by D204, a 2.5 volt reference), its output goes negative. This turns on Q203, allowing current to flow through L201 onto C203, raising the voltage at the input of U205. Once the voltage across U205 is greater than 2.5 volts (plus a small amount of hysteresis set by R219 and C205), U206 shuts off Q203. Current continues to flow through L201 during the off time since current can't change instantly through an inductor. This causes the voltage at pin 2 of Q203 to flyback negatively and be clamped by D203. The voltage across U205 will now decay until it is less than 2.5 volts, which begins the cycle again.

(page 2/11)

U205, a LT1085, is a low dropout adjustable regulator which filters the output of the step down section. U207 increases the V DRIVE signal of 012 volts to 0-33 volts which programs the common tap of the step-up high voltage transformer.

Inverter

U201 is a LM555 timer configured as an astable multivibrator at a frequency of 40 kHz with about a 60% duty cycle. U202 and U203 split this into two phases of 20 kHz at a 30% duty cycle. U204 (SN75372) is a high current MOSFET driver for the FETs (Q201,Q202) that drive the high voltage step-up transformer (pages 9/11 through 11/11). D201 and D202 clamp excessive inductive flyback voltage.

If the primary current exceeds about 5.3 amps, R212 - R215 and U301C sense the primary side current and shut off the drive to the inverter (and hence the high voltage). They do this by activating the HV OFF line (page 3/11), which latches the high voltage off until the processor releases it. The high voltage can also be turned off by voltage or current trips and by the processor.

Limits and Trips

U301 is a quad comparator that compares both the scaled output voltage and current to both the limit and trip values which are set by the processor and D/A. If a trip value is exceeded, the high voltage is shut off through the HV OFF signal and the change of status is reported to the processor. If a limit is exceeded, only the change of status is reported. The processor can also set the HV OFF line via the SHUTDOWN line.

U306 is a one-shot circuit used as a watch dog timer. Unless the microprocessor resets it every 10 ms, the one-shot times out, turning off the high voltage and forcing a system reset.

A/D's and D/A's

U410 is a 12 bit digital to analog converter that is loaded 4 bits at a time from the processor. Its output current is converted to a voltage by U402B to provide a 0 to -10.00 VDC referenced from LH0070 (U406), a precision reference. U407A, U407B and U405 form a programmable low offset inverter. After scaling, the output covers a range of

-10.24 to +10.24 VDC with 13 bits of resolution and 2.5 mV bits. These outputs are multiplexed to

(page 3/11)

(page 4/11)

6 sample and hold circuits that provide control voltages and outputs. Each sample and hold is refreshed every 12 ms.

U402A and U404 form an integrating, successive approximation analog to digital converter. U409 determines the input to be sampled and integrates it through R404 on to C401. Then a successive approximation 13 bit analog to digital conversion is made using the D/A converter and comparator U404. This takes about 100 µs.

Microprocessor Control

The microprocessor, U501 (a Z80), is clocked at 4 MHz by X501. U502, an 8K ROM, contains the firmware and calibration constants. The 2K static RAM, U503, is backed up by a lithium battery, BT501. A power down circuit protects the RAM contents by disabling the chip-select with Q501 if a reset is asserted. The battery should have a useful life of 5 to 10 years and shouldn't need to be replaced.

U504 and U505 generate chip selects for the various input and output ports. U506 and U512 are input ports for status information, rear panel switches, and the HV ON/OFF switch on the front panel.

U509 and related parts form the power on reset circuit. During power on, it asserts a reset for about 250 ms so the supply voltages can stabilize. If the +5 V power supply dips below 4.5 V (determined by the +10.00 V reference), it asserts a reset that will last until the voltage recovers and a reset cycle has occurred. If the watch dog timer isn't updated every 10 ms, it triggers U511, which also forces a reset. During a reset, in addition to the processor being reset and the RAM being disabled, the high voltage is turned off.

(page 5/11)

GPIB and Front Panel Interface

(page 6/11)

GPIB

The GPIB (IEEE-488) interface is provided by the TMS9914A controller, U601. U602 and U603 are buffers to the GPIB connector, which is connected to J602. U601 is programmed to interrupt the processor whenever there is activity addressed to the power supply.

Front Panel Interface

Front Panel

(page 8/11)

The front panel has a 6 phase, multiplexed LED display and keyboard. U604 is a data bus latch for U605, a high current driver that provides the strobe signals to the front panel. Each strobe selects 2 digits and 2 or 3 LED's to be refreshed. Only one strobe is active at a time. U606 and U609 are pull down lines for the digits with 390 Ohm current limiting resistors (N601 and N602). The individual LEDs are pulled down separately by U613AU613C with 12 Ohm current limiting resistors(R602-R604). They are separated from the digit pulldowns because the LED's require much more current than the high efficiency 7 segment displays. Strobes 2, 3 and 4 also go to the keypad matrix which is read by U612, an input latch.

U610, a divider chip, takes the system clock of 4 MHz and divides it by 4096 which gives a 977 Hz signal. This provides the processor with a a real time interrupt which is used to synchronize updating the display, analog voltages, and instrument status.

Low Voltage Power Supplies

(page 7/11)

The front panel consists of twelve 7 segment high efficiency displays, a ±1 display, 13 LED's, a keypad and the high voltage on/off switch.

The displays are multiplexed by 6 strobes. During each strobe, two of the twelve displays are on. In addition, up to 2 (of a maximum of 3) LEDs are on to indicate the instrument status and polarity. The ±1 display is driven the same as the LEDs, but it has larger current limiting resistors R1 and R2 (390 Ohms), since it is far more efficient then the ordinary LEDs. Finally strobes 2, 3 and 4 go to the keypad matrix allowing 1/3 of the keys to be read during each of these strobe cycles.

The High Voltage ON/OFF switch is separate from the keypad matrix. Its signals go directly back to one of the processor's input ports.

High Voltage Section

Note: These boards are covered to prevent

accidental shock or injury. DO NOT ATTEMPT TO OPERATE THE UNIT WITH THE COVER OFF !!!

Line power comes in at the power entry module where it passes through a fuse and then a RFI filter. Both the hot and neutral leads are switched. Next, the voltage passes into the line voltage selector. The transformer primary is tapped for 4 different voltages: 100,120, 220, 240 VAC, 50 or 60 Hz.

The transformer has 3 secondaries, 32 VAC non centertapped and 32 VAC and 15 VAC, center tapped. The 15 volt tap is rectified by D703 and D704. It is filtered by C706 to make +8 VDC unregulated. Then it is regulated by U704 to make the +5 VDC for the processor, digital logic. U707 regulates the +5VDC for the LED display. The 32 volt tap is full wave rectified by U701 and filtered by C702 and C705 to provide ±18 VDC. These are regulated by U702 and U703 to make ±15 VDC for the analog circuitry.

The 32 volt non center tapped winding is rectified by D701 and D702, and filtered by C701. It provides +35 VDC at 1 amp to the pre-regulator for the high voltage section. U705 provides a regulated +33 VDC for the control circuits in the preregulator.

PS310 (page 9/11)

The biggest difference between models in the PS300 series is the high voltage section. They are configured to provide the proper combination of voltage and current through the use of different diode-capacitor multiplier circuits. For the PS310 (page 9/11), the output of transformer T1 is full wave rectified by diodes D1-D4 and filtered by C3 and C4. Poles A and B of switch SW1 change the polarity of the high voltage output and pole C reports the polarity to the processor. C3, C4 and R1-R3 are an output filter to reduce switching noise. R4, R5 and R8 form the divider to provide the voltage sense signal; R6 and R9 are the current sense resistor.

PS325 (page 10/11)

The PS325 (page 10/11) is similar to the PS310 except the transformer output is fed to the voltage doubling circuit of D1, D2, C1 and C2. Switch SW1 acts in the same fashion as on the PS310. The voltage sense circuit consists of R4, R5, R6 and R8. R7 and R9 are the current sense resistor. The output filter is slightly different to reflect the changes in output voltage and current.

PS350 (page 11/11)

The PS350 (page 11/11) is similar to the other two, but it has a voltage quadrupler made up of C1, C2, C3, C4, D1, D2, D3 and D4. Switch SW1 acts the same and R9 is again the current sense resistor. The voltage sense circuit is made up of R2 and R3. C5 provides some additional phase compensation. Finally the output filter is set up for higher voltage and lower current.
