1. General Information

1.1 Introduction

This manual contains specifications, installation, operation and programming of 63600 Programmable DC Electronic Load.

The Chroma 63600 Programmable DC Electronic Load System consists of model 63600-1, 63600-2, 63600-5, 63601-5 mainframes, and 63630-80-60, 63610-80-20, 63640-80-80, 63630-600-15 and 63640-150-60 Electronic Load modules.

1.2 Description

The 63600-5, 63601-5 Electronic Load mainframes contain slot for 5 load modules. The mainframe 63600-5 contains a processor, two System Bus ports, a USB port, a GPIB card (optional), an Ethernet card (optional), front-panel keypad, a memory channel indicator, and other circuits common to all the load modules.

The Electronic Load, composed of any of a mainframe plugged-in with at least any of a module, offers stand-alone operation mode. In addition, the mainframe 63600-5, 63601-5 can be controlled via A636000 GPIB or A636001 Ethernet or USB bus by a remote computer (see Chapter 5 Remote Operation), or via System Bu s by the remote controller.

The functions of 63610-80-20, 63630-80-60, 63630-600-15, 63640-80-80, 63640-15060…etc. are all the same except the variations on input voltage, load current, and power ratings. An individual module may have one or two channels. Each channel has its own channel number, load & measurement connectors, and operates independently in constant current (CC) mode, constant resistance (CR) mode, constant voltage (CV) mode, constant power (CP) mode, or Constant Impedance (CZ) mode.…etc.

The 63600 Programmable DC Electronic Load System is used for design, manufacturing, and evaluation of DC power supplies, batteries, and power components.

2.4 Installing the Modules

Use standard anti-static work practices when you handle and install

Chroma 63600-5, 63601-5 Mainframe has room for five single-width Loads (63610-80-20, 63630-80-60, 63630-600-15, 63640-80-80, 63640-150-60); Loads can be combined in the Mainframe in any order. The module installation procedures for all Mainframes are the same. No special tools are required to install Load Module to Mainframe.

Procedures

1. Power off the Mainframe and disconnect the power cord.

2. Remove any packing materials on the Mainframe.

3. Start to install the modules in the slot (see Figure 2-2).

4. Plugging and sliding the load module into the Mainframe slot along the rail until it locked and fastened.

5. Install each additional module in the next slot likewise.

2.4.1 Channel Number

The channel number of the Load is determined by the module location in the Mainframe starting from the farthest left slot. As some Load (63610-80-20) has two channels in one module, channel 1 and 2 are always on the farthest left slot of the Mainframe, and channel 9 and 10 on the farthest right. The channel number is fixed for Mainframe even the Load module is empty. Figure 2-3 shows the channel assignments for a Chroma 63600-5 Mainframe containing two Loads of 63630-80-60 single channel module, and two Loads of 63610-80-20 dual channel module. Channel number is automatically assigned to 1, 3, 5, 6, 7, and 8. Channel 2 and 4 are skipped as single module is applied.

Figure 2-3 Example of Channel Number

2.5 Installing the Mainframe

The Electronic Load can operate well within temperature range from 0 to 40 degree C. However, you must install the Electronic Load in an area that has enough space around for adequate air flowing through and escaping from the back. You must leave at least 10 cm (4 inch) space above the unit for air circulation. Note that the unit foot stock has enough vertical space for air circulation when it is stacked. The Mainframe foot stock can be removed for rack mount.

If you install the equipment on top of your Electronic Load in a cabinet, you must use a filter panel above the unit to ensure adequate air circulation. A 1U (EIA standard) panel is sufficient.

2.5.1 Line Voltage

The Electronic Load can operate with a 115/230 Vac input as indicated on the rear LINE label. The detailed line voltage input range is shown in section 1.4 Specifications. The Electronic Load can automatically switch correct line voltage range t o corr espond to your nominal line voltage, when you connect the power cord to correct line voltage and turn on the Electronic Load.

connected to ground.

WARNING

The line fuses will protect the Electronic Load from incorrect voltage

2.5.2 Turn-On Self-Test

Check the following before turning on the Load.

1. The nominal line voltage of the AC input socket is in the range of 100-120/200-240 Vac.

2. The power cord is connected to the AC input socket.

The power cord supplies a chassis ground through a third connector. Be sure that your outlet is of three-conductor type with the correct pin

Power on the Load by the front panel switch on Mainframe and observe the display. Immediately after turning on, the Electronic Load executes a self-test that checks firmware and communication. The Load Module displays,

and then displays the model number as well as firmware version,

63630-80-6 0 < --- Model Number [636308000066] < --- Serial Number G_FW : 1.00 C1_FW: 1.00

If any error is found during self-test, the display will stop here. Check the Load and Mainframe connection when an error occurs. When the self-test completes, the VFD will display measurement V & I. The dual channel module goes to L channel.

In case of failure, return the Mainframe or Load module to Chroma sales or service office for repair.

When using Y-type (U-type) terminal to connect the load terminal, do not exceed 30kgf-cm when securing it using Chroma terminal fixture.

WARNING

2.6 Application Connection

2.6.1 Load Connections

To satisfy safety requirements, load wires must be heavy enough not to overheat while carrying the short-circuit output current of the device

load wires which have over 2.0μH inductance must be avoided from the UUT to our load. We have made the adaptable Load Cables along with the Load. They are better for application connection being the interface

Input connections are made to the + and − terminal connectors on the front of each Load module. The major considerations for input connections are the wire size, length and polarity. The minimum wire size required to avoid overheating may not be enough to maintain good regulation. The wires should be large enough to limit the voltage drop to less than 0.5V per lead. The wires should be as short as possible, and bundled or tied together to minimize inductance and noise. Connect the wire from the PLUS (+) terminal on the module to the HIGH potential output terminal of the power supply (UUT). Connect the wire from the MINUS (−) terminal on the module to the LOW potential output terminal of the power supply (UUT). Figure 2-4 illustrates the typical setup of the Load module to the UUT. T he connecting way is: First Put the Y-type terminal wire into Load terminal from the bottom of the load terminal, and let Y-type terminal touch the metal post of the load terminal tightly. Then, turn the banana binding socket of the Load terminal for connection by your hands, and finally use a tailormade spanner to make the connection tightly. Figure 2-5 shows the Load connection with the tailor-made spanner.

Each terminal with banana binding socket can easily use the banana plug to make load connection. It is the other way for load connection. But normally the banana plug can carry only 20 or 10 Amps at most. Before you use the banana plugs for connections, you must check the maximum current rating of the banana plugs and the wire. The connection with the banana plug isn’t fixed in the banana binding socket tightly. So, when the output voltage of the power supply (UUT) is equal to or over 70VDC, to prevent accidental contact with hazardous voltage,

2.6.2 Remote Sensing Connections

There are two sensing points in the Electronic Load module. One is measurement at Load terminal, and another is at Vsense. The Load module will automatically switch to Vsense when Vsense terminals are connected to UUT, otherwise it will measure at Load terminals. Remote sensing compensates for voltage drop in applications that require long lead lengths. It is useful when a module is operating in CV or CR mode, or when it needs precise measurement. Figure 2-4 also illustrates a typical setup for remote sensing operation.

use. Follow the precautions listed below for operation.

1. The internal resistance of each Electronic Load is different and varied when connecting to a UUT. Use a professional digital power meter if more accurate voltage measurement is required.

2. Use t he load UUT Vsense or Local terminal to do voltage measurement. Connect the negative ends is suggested to avoid any possible loop current that may affect the measurement result.

3. Cont act Chroma technical service center if there is a need to use

2.6.3 Parallel Connections

Figure 2-6 illustrates how modules can be paralleled to increase power dissipation. Modules can be directly paralleled in CC, CR or CP mode. Modules cannot be paralleled in CV mode. Each module will dissipate the power it has been programmed. For example, if two modules are connected in parallel, one is programmed 10A, and another is 15A, the total current drawn from the source is 25A. Restriction on number of parallel modules depends only on total modules available in the multi-mainframe environment described in the next section.

Figure 2-6 Parallel Connection

2.6.4 Multi-Mainframe Connections

The Electronic Load system offers multi-mainframe synchronized connectivity for up to 4 mainframes. The user is allowed to connect either System Bus1 or System Bus2 port on rear panel of a mainframe as input from previous mainframe, and use the remainder as output to the next mainframe. For a systematic configuration, it is strongly recommended to connect 2 mainframes in the way as from System Bus1 on a mainframe to System Bus2 on the other mainframe. Figure 2-7 indicates how to connect mainframe1 and mainframe2 along with extend to mainframe3.

2.7 Remote Control Connection

The remote operation of Load can be done through GPIB, Ethernet, or USB interface. These connectors on the rear panel connect the Load to the controller or computer. The GPIB and Ethernet interface of the electronic load is optional. Connect the Remote Controller to the Electronic Load before powering it on. If you have not done this, Load will shut down, or the fuse for remote controller in Mainframe will be broken.

2.8 GPIB Card Setup

The Model 63601-5 only provides commands for save and recall functions with no support of manual operation.

3. Operation Overview

3.1 Introduction

Chroma 63600-5, 63601-5 multiple electronic load mainframes are suitable for design, manufacturing, testing and quality assurance for electronic products. The Mainframe contains five slots of load modules. Each Load module occupies one slot depending on the power rating of the module.

The Mainframe 63600-5, 63601-5 can dissipate up to 2,000 watts when it is full loaded. It contains a processor, two System Bus ports, a USB port, a GPIB card (optional), an Ethernet card (optional), front panel keypad and display, and PASS/FAIL signals. The built-in remote control function enables you to control and read back the current, voltage and status. The SYNC function on the Mainframe synchronizes each module when the module current/ voltage level changes. The Save/Recall feature allows you to save up to 100 files, 10 programs, and one default setting. All of them can be saved in module EEPROM for future use.

The Load Module has one cooling fan. The fan speed automatically increases or decreases when the module power rises or falls. This feature reduces overall noise level as the fans do not always run at maximum speed.

Each module can operate independently in constant current (CC), constant resistance (CR), constant voltage (CV), constant power (CP), and constant impedance (CZ)…etc. An individual module may have one or two channels. Each of them has its own channel number with its own input connectors, and can be turned on/off or short-circuited independently. If your application requires a greater power or current capacity than one module can provide, you have to connect load modules in parallel in CC, CR, or CP mode.

Each load module can be controlled any remotely via GPIB / Ethernet / USB / System Bus interface. Once a channel is selected or addressed, all subsequent commands go to that channel till another channel is selected or addressed. The operation of all modules in the Mainframe is similar in spite of power ratings; meanwhile each module has a keypad to control itself.

Each module operates independently in CC, CR, CV, CP, or CZ mode as a load and simultaneously measures current, voltage, or power level. The user is allowed to off-line edit above mentioned parameters. Beside, in any of the operation modes, when active, the online change of parameters changes the Electronic Loading accordingly, thus making it easy to achieve an optimized test condition and then saved for later use.

The module allows the user to enter specification of a UUT including V and I for later GO/NG check. In addition, the real time measurement bar on the VFD display indicates the degree of deviation from specification and guides the users in adjusting to fulfill spec.

This chapter covers the interpretation of the front and rear panel description, the initial setup, and the operation of static load under different operating modes including CC, CR, CV, CP and CZ, and CC dynamic load.

3.4 Local/Remote Control

Local (front panel) control is in effect immediately after the power is applied. The front panel keypad and display allow manual control of individual module when Load is used in bench test applications. Remote control goes into effect as soon as the Mainframe receives a command via GPIB / Ethernet / USB / System Bus interface. When the remote control is in effect, only the computer/remote controller can control the Load. The front panel keypad has no effect except the LOCAL key.

MODE

Most of the functions that perform remotely can be done locally too at the Load Module front panel. The keypads on the Mainframe can perform simple functions like specific setting, data lock operation, save/recall setting.

Details of local operation are given in Chapter 4 Local Operation. Fundamentals of remote programming are described in Chapter 5 Remote Operation.

3.5 Modes of Operation

There are five modes of operation: Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV), Constant Power (CP), and Constant Impedance (CZ).

When you press key to program a mode, the module will change to a new mode. In change of modes the module’s input is momentarily disabled before a new mode is enabled. This ensures the minimum overshoots during mode change. The parameters in current, resistance or voltage mode can be programmed easily when the mode is selected.

All data set in CC/CR/CV/CP/CZ mode will be rescaled to fit the resolution of current/voltage levels or slew rate. In local mode any value can be set from the keypad. But, if ther e is no upper and lower limit that would cause an error. The Load automatically selects data, which is rescaled from the programmed value, truncates and checks high, low boundary before fitting it into the memory. When the programmed data is over the boundary, the Load will set the maximum or minimum level. In remote mode the programmed value cannot be over boundary. An error will occur when the data is over the maximum or minimum value.

In CC mode, the Load will sink a current in accordance with the programmed value regardless of the input voltage. To enter into the CC mode, press the key a few times

until the VFD displays CC mode.

Current Ranges (Low, Middle, High)

Current can be programmed in any of the three ranges, low range, middle range and high range. The low range provides better resolution at low current setting. If any value is over the maximum of low range, you must select the middle range. When any value is over the maximum of middle range, you must select the high rang e. To change the ra nge, press the

key few times until the LED range indicator is active at you want to select.

The mode change will affect the module, so will the change of range. Both of them will cause the input to go through an off state. If the CC mode of Load module is active, the new setting will change the input immediately at a rate determined by the slew rate setting.

Static Load Mode

In CC mode two operation modes Static load and Dynamic load are available for selection. Static function checks the stability of output voltage from a power supply. In some modules

(single channel module) there are two current levels (A or B) for static function. Both A and B states use the same range. You can program the current loading to two different levels, A and B, and then switches manually between two programmed states A and B using the

key on the module’s keypad. Slew rate determines the rate at which Load level

changes from one load level state to another. Figure 3-10 shows the current level of load module after pressing key.

State A=4A, State B=2A, Rise =0.2A/μs, Fall =0.08A/μs

Dynamic Load Mode

There are two Operation Modes for dynamic load: Dynamic load mode and Dynamic load frequency sweep mode. Press to select Dynamic load or Dynamic load frequency

sweep mode. Dynamic load operation offers the user to program 2 load levels (Load1 and Load2), load

durations (T1 and T2), slew rates (Rise and Fall), and Repeat times (RT). During operation, the loading value is switched between those two load levels according to your specific setting parameters. The Dynamic Load is commonly used for testing the UUT’s performance under high speed, transient loading condition.

Load1=4A, Load2=2A, Rise =0.2A/μs, Fall =0.2A/μs, T1=10ms, T2=10ms, RT=0

Figure 3-11 Dynamic Current Waveform

The STATic/DYNAmic functions can also be selected through key on the Load module.

Slew Rate (Rise, Fall A/μs or mA/μs)

Slew rate determines the rate at which the current input of a module change to a newly programmed value. There are two slew rate values, which are rise rate and fall rate.

Voltage Ranges (Low, Middle, High)

There are three voltage ranges for voltage measurement and Von voltage setting. The low range provides better resolution at low voltage measurements. If the value is over the maximum of low range, you must select the middle range. When the value is over the maximum of middle range, you must select the high range. The CC mode voltage range selection is in configuration setting.

Repeat time s ( ti mes)

The Load provides a unique simulation capability, which allows users to set the number of the period times. When the tim es is set a limited period times, the load is automatically off till the period time is over. If you want to continue the load with unlimited times, just to set the value to be zero.

Dynamic Load Frequency Sweep Mode

Figure 3-12 CC dynamic Frequency Sweep Current Waveform

The Load offers a unique CC dynamic frequency sweep with variable frequency to find the worst case UUT voltage.

Frequency Sweep Function operation enables you to program two load levels (Load1 and Load2), Start frequency, End frequency, Step frequency, Dwell time, duty, slew rate (Rise and Fall). During operation, the loading value is switched between those two load levels according to such user specified parameters.

Frequencies (Start frequency, End frequency, Step frequency Hz)

The setting range of the Frequencies is from 0.01Hz to 50kHz.

Dwell time (s)

Dwell time is the elapse time of each setting step frequencies from start frequency to End frequency. T he setting range of the Dwell time is from 1ms to 100s.

Duty (%)

The duty in percentage of Load1 is in one dynamic loading cycle, and it is expressed by %. The duty can be set from 1%-99%. The Duty setting will be limited within the transition time of the two load levels.

3.5.2 Constant Resistance Mode

Figure 3-13 Constant Resistance Mode

In CR mode, the Load will sink a current linearly proportional to the input voltage in accordance with the programmed resistance. This mode is operated under the F/W calculation. That is, take the measured V data, divide the resistance setting and get the I setting value. There is a moving average calculation process for the measuring data. High frequency parts will be removed, and the minimum transient time of the loading current in this mode is 400us. To avoid the load current change caused by the input voltage variation, the power source impedance should be as low as possible, and remote sensing cable must be used to sense load input voltage when high sink current (low setting resistance) is programmed.

Voltage Ranges (Low, Middle, High)

Resistance can be programmed in any of low, middle, or high range. The low range is used for input voltage in low voltage range. The middle range is used for input voltage in middle voltage range while the high range is for input voltage over middle voltage range. The current range in CR mode is high range.

If input voltage is over the maximum of low range, you must select the middle range. When input voltage is over the maximum of middle range, you must select the high range. To

change the range, press the key few times until the LED range indicator is active at you want to select. In some modules (single channel module) there are two resistance levels (A or B) for CR function. Both A and B states use the same range. You can select state A or

state B through the key on the module’s keypad. Slew rate determines the rate at which load level changes from one load level state to another.

In CV mode the Load will sink current to control the voltage source in programmed value. This mode is operated under the F/W calculation. That is, take the voltage setting, divide the measured output current of UUT’s CC mode and get the suitable resistance as the equivalent resistance of the Cells. Then, take the voltage setting, divide the suitable resistance and get the I setting value. There is a moving average calculation process for the measuring data. High frequency parts will be removed, and the minimum transient time of the loading current in this mode is 400μs.

Voltage can be programmed in any of low range, middle, or high range by the key. The low range is used for input voltage in low voltage range. The middle range is used for input voltage in middle voltage range while the high range is for the input voltage over middle voltage range.

In some modules (single channel module), there are two voltage levels (A or B) for CV function. You can select state A or state B using key. Both A and B states use the

same range.

In CP mode, the Load will sink a current according to the programmed power. This mode is operated under the F/W calculation. That is to divide the power setting by the measured V data and get the I setting value. There is a moving average calculation process for the measuring data. High frequency parts will be removed, and the minimum transient time of the loading current in this mode is 400μs.

Power can be programmed in any of low range, middle, or high range by the key. The low power range is operated under low current range mode. The middle power range is operated under middle current range mode while the high power range is under high current range mode.

In some modules (single channel module), there are two power levels (A or B) for CP function as other modes. Both A and B states use the same range. You can select CPLA or

In CZ mode, the Load will sink a current according to the programmed impedance. This mode is operated under the F/W calculation. That is, take the measured V data, divide the Impedance setting and get I setting value.

The loading of channels with the ALL RUN function turned on, can be controlled via other channels with ALL RUN settings turned on. Channels with ALL RUN turned off will load On/Off individually.

3.7 Measurements

Each module measures current and voltage of a UUT. The sampling rate is about 2μs. Voltage and current measurements are performed with a 16-bit resolution of full scale ratings.

3.8 Slew Rate & Minimum Transient Time

Slew rate is defined by the change in current over time. A programma ble slew rate allows a controlled transition from one load setting to another to minimize the induced voltage drops on inductive power wiring, or control the induced transients on a test device. If the transient from one setting to another is large, the actual transient time can be calculated by dividing the current transition by the slew rate. The actual transition time is defined as the time required for the change of input from 10% to 90% or from 90% to 10% of the programmed excursion. If the transition from one setting to another is small, the small signal bandwidth of Load will limit the minimum transition time for all programmable slew rates. Because of the limit, the actual transition time is longer than the expected time based on the slew rate. Therefore, both minimum transition time and slew rate must be considered when determining the actual transition time. The minimum transition time is from 10μs in the CC mode and CC dynamic mode slew rate setting.

3.9 Start/Stop Sink Current

To simulate the transient characteristics of load to UUT, the critical problems are when and how the Load starts sinking current from UUT. You may set the conducting voltage Von to solve the problems. The Load will start or stop sinking current when the UUT output voltage reaches the Von voltage. You can start sinking current when the load is ON and the input voltage of the module is over Von voltage, but stop sinking when load is OFF or the input voltage is below Von voltage. See Figure 3-17 and Figure 3-18 for start/stop sinking current.

There are two operation modes for Von control, latch and non-latch. Latch means that when voltage is over Von voltage, Load will start sinking current continuously in spite of input voltage drop is below Von voltage. Non-latch means that when input voltage is below Von voltage, Load will stop sinking current. The Von voltage and its operation mode are set in configuration.

Page 67

Operation Overview

3-15

Figure 3-17 Start Sinking Current (Von Non-Latch)

Figure 3-18 Stop Sinking Current (Von Non-Latch)

In the battery discharge timing measuring mode, you may set the conducting voltage Voff to avoid repeatedly start sinking and stop sinking current when the UUT output voltage is repeatedly up and down near the Von voltage.

When you set the conducting voltage Voff, the Load will start sinking current when the load is ON and the UUT output voltage reaches the Von voltage, and stop sinking current when the UUT output voltage is below the Voff voltage. Then, the load is OFF. I t will not sink current when the UUT output voltage reaches the Von voltage again, until you turn it on.

The conducting voltage Voff is only available in Timing mode, and to avoid the logic error, the Voff should be less than or equal to Von.

releasing it to return to normal operation. The actual value of electronic short depends on the limit is the maximum current range and

the maximum power range the Load can supply. Turning on the short circuit does not affect the programmed setting, and Load input will return to the previous programmed values when the short circuit is turned off.

Load will automatically stop sink current and finish the operation after the timing measurement is taken without pressing the key.

3.13 Sine Wave Dynami c

If the load has a unique sine wave loading current that allows the user to set the loading current bias (I_DC), the loading sine wave (I_AC) and sine wave frequency (Frequency). The lowest point of sine wave cannot be smaller than 0 ampere. As Figure 3-20 shows Ch1 is the actual loading current waveform and Ch2 is the voltage waveform of the UUT (AC component.)

Figure 3-20

The dynamic current loading bandwidth varies with the load designed on the market and the response speed of loading slow rate is different by the bandwidth. For instance, using two loads of different brands to set the dynamic current conditions as I

The result shows in Figure 3-21 Load of A Brand and Figure 3-22 Load of B Brand are set in the same current slew rate but with different voltage waveform. Therefore, using sine wave loading to test the dynamic load modulation rate will not cause any measurement error due to different load design and different bandwidth. It wil l make t he test more perfect.

3.14 OCP Test Function

The Load provides ramped up current for the load to test the UUT voltage whether has reaches trigger voltage level to judge the OCP protection movement normally or not. This test checks the response of one UUT output under overloaded condition.

3.15 Program Sequences Function

The Program Sequences Function feature is very powerful. The electronic load has 10 programs that can set up 100 sequences maximum. For instance, when program 1 is set up with 5 sequences and program 2 is set up with 8 sequences, the rest programs from 3 to 10 can set up the remaining 87 sequences. Please see section 4.6.5 for setting and running the Program Sequences Function.

3.16 Load On/Off

A module’s input can be toggled on/off through the key on module, or the remote control. The on/off change for input is done according to the slew rate.

Turning off the load does not affect the programmed setting. The load will return to the previous programmed values when the Load is turned on again.

3.17 Protection Features

Each load module has the following features: Over Current Protection, Over Power Protection, Over Temperature Protection and Over Voltage, Reverse Voltage Warnings.

ENTER

CAUTION

The appropriate bits in the Mainframe’s status registers are set when any of the protection features listed above is active. The Load’s buzzer will beep to inform you till the protection status is reset. When any of the protections occurs, the Load input will turn off.

● Over Voltage Warning

The over voltage protection circuit is set at a level slightly above the voltage range specified in the Load specification. The over voltage (OV) and voltage fault (VF) status register bits are set when the OV condition occurs and will remain set till they are reset. The Load module will appear OVP when over voltage protection occurs.

● Over Current Protection

When the Load is operating in CR or CV mode, it is possible for a module to attempt to sink current more than it is rated for. The limit level of current is set at a level slightly above the current of the Load. The over current (OC) and current error (CE) status register bits are set when the OC condition occurs, and will remain set till they are reset. The Load module will appear OCP when over current protection occurs.

● Over Power Protection

The overpower protection circuit is set at a level slightly above the power range specified in the Load specifications. The over power (OP) and power error (PE) status register bits are set when the OP condition occurs, and will remain set till they are reset. The Load module will appear OPP when overpower protection occurs.

● Over Temperature Protection

Each Load has an over temperature protection circuit, which will turn off the load if internal temperature exceeds the safety limit. The over temperature (OT) and temperature error (TE) status register bits are set when the OT condition occurs, and will remain set till they are reset. The Load module will appear OTP when over temperature protection occurs.

● Reverse Voltage Warning

The Load conducts a reverse current when the UUT polarity connection is not correct. The maximum safe reverse current is same as the Load rated current. If the UUT reverse current is over the rated current of Load, the Load may be damaged. If a reverse voltage condition is detected, you must turn off the power to UUT immediately, and correct the connection. The reverse voltage (RV) and voltage fault (VF) status register bits are set when the RV condition occurs, and will remain set till they are reset. The Load module will appear REV when reverse voltage protection occurs.

● Max sine wave current

When the LOAD is operating under SINE WAVE DYNA function, the panel will show “MAX LIM” once the loading current caused the voltage to change exceedingly beyond the condition allowed.

All of the above protection features will latch when they are tripped. When any of the protections occurs the module will turn off the load input, and beep till you remove the

condition and reset the protection by pressing key on the module.

When high voltage models are in used, the “CC,CP V RANGE SELECT”

default protection voltage range is about 0.02V~1.2V.

CAUTION

● LVP

The desi gn of LVP is mainly to prevent the UUT from sudden voltage drop to 0V and rise again when the Von point is set to 0V or in current loading state at “LOAD ON” as it could cause the voltage or current to overshoot. Also it could damage the UUT or Electronic Load if the UUT is connected.

The LVP is a default protection voltage set internally. When t he Electronic Load is under this voltage and in loading mode, it does not perform current loading until the external voltage is larger than the LVP set protection voltage. Therefore, there will be no overshoot even though the Von point is set to 0V or the voltage is suddenly dropped to 0V and raised again. This way is to prevent the overshoot to damage the UUT and Electronic Load.

3.18 Save/Recall Setting

The Electronic Load setting for all channels can be saved and recalled for various test setup use. In the Save file 00~99, each file has the settings of Configure, CC, CR, CV, CP, CZ, CCD, CCFS, TIMING, S INE WAVE DYNAMIC and OCP TEST without AUTO SEQUENCE. Moreover, there is an addition file for power on setting file which the contents are the same as File 0 ~ 99. Once there is a Load on or it is exited from Configure screen during normal operation, the present settings will be saved in this file. When the SAVE key is pressed, it will not only save the settings to the file user specified but also save them to the Power On file. To recall the saved settings (file 00~99), press ▲or ▼ key to adjust the file number (file

3.19 External Waveform Control

The external dynamic test, operated in the CC mode, is similar to that under the Dynamic test, but the load level switching is controlled by the duty cycle of an External signal. It wo r ks the same way as the dynamic test except that the Period control signals are not generated internally, but are inputted from V EXT. Connectors are on the rear panel. A 0-to-10V external signal corresponds to the 0-to-full scale input range, so that users should apply DC offset for the external signal in the range from 0 to 10V. For the configuration of external waveform control usage, refer to section 4.7.1 for details.

3.20 Voltage & Current Monitor

Each channel of the Load has two isolated connectors to monitor load voltage and current, the output signal to I MON and V MON. Connectors are on the rear panel. A 0-to-10V output signal corresponds to the 0-to-full scale load V&I range.

4. Local Operation

4.1 Introduction

This chapter describes how to operate the electronic load from the local panel in details. The descriptions include: Mainframe panel control, Module panel control and indicators.

In order to use the front panel keys to control the electronic load, local operation must be in effect. Immediately after the power is applied, local operation will be in effect. When local operation is in effect, you can operate each module independently, and use the display with keypad on the Load front panel to control the Load. The input voltage/current is displayed on the module’s display.

Each module operates independently in CC, CR, CV, CP or CZ mode as a load and simultaneously measures current, voltage, and power level. Each module also operates independently in the dynamic load or dynamic load frequency sweep, or the Advance functions including Timing Measurement, SINE WAVE DYNA, OCP Test, and Program Sequences. The user is allowed to off-line edit above mentioned parameters. Beside, in any of the operation modes, when active, the on-line change of parameters changes the Electronic Loading accordingly, thus making it easy to achieve an optimized test condition and then saved for later use.

The module allows the user to enter specification of a UUT including V, I, Watt for later GO/NG check. In addition, the real time measurement bar on the VFD display indicates the degree of deviation from spec. and guides the users in adjusting to fulfill spec.

This chapter covers the interpretation of the front and rear panel description, the initial setup, the operation of the different load modes including CC, CR, CV, CP and CZ, the operation of the two dynamic load modes including dynamic load and dynamic load frequency sweep, and the operation of the Advance functions including Timing Measurement, SINE WAVE DYNA, OCP Test, and Program Sequences.

In remote state, the keys on the front panel have no effect. Only remote controller can program the Load. The display of module will show the present input voltage and current readings or the last display while local state is in effect. The display of the Module will show REMOTE message.
