Safety

Warnings and cautions are defined and formatted in this manual as shown below.

WARNING

Describes a potential hazard which could result in injury or death, or, a procedure which, if not performed correctly, could result in injury or death.

CAUTION

Describes a procedure which, if not performed correctly, could result in damage to data, equipment, or systems.

WARNING—High Energy and High Voltage

Exercise caution when using and calibrating a power supply. High energy levels can be stored at the output voltage terminals on a power supply in normal operation. In addition, potentially lethal voltages exist in the power circuit and on the output and sense connectors of a power supply with a rated output greater than 40 V. Filter capacitors store potentially dangerous energy for some time after power is removed.

CAUTION

Operate the power supply in an environment free of flammable gases or fumes. To ensure that the power supply’s safety features are not compromised, use the power supply as specified in this manual and do not substitute parts or make any unauthorized modifications. Contact the service technician for service and repair help. Repairs must be made by experienced service technicians only.

CAUTION

For Use as a Battery Charger When you are using any of these power supplies for battery charging applications, it is essential to provide an appropriately sized fuse or circuit breaker in series between the power supply output and the battery. Installation of a protector (fuse or DC circuit breaker) rated for about 115% of the maximum current rating of the power supply and designed specifically to interrupt the DC voltage of the battery, will provide adequate reverse polarity current protection. Where several power supplies are in parallel, it is best to fuse each one, rather than one large fuse for all.

About The XDC Power Supply

Overview of Operation

Power ON Power ON describes the period between the time the AC power is turned ON and the

time the power supply is ready for normal operation. Each supply comes with a series of factory default settings that may be in effect at the conclusion of the Power ON period. These include:

• Output OFF: No current is sent to the DC output connections. You must press

Out ON/OFF to activate the supply output.

• Voltage 0V: The Voltage setpoint is zero.

• Current 0A: The Current setpoint is zero.

• Local mode operation

The output state depends on the Power ON output setting. You can customize the Power ON settings to suit your needs. See “Configure Power ON Settings” on page 84 for more information.

Control

Modes

One local method and 4 remote methods are available for controlling the power supply:

• Local Mode: Where the user operates the menu keypad and knobs

• RS-232: Where the user operates the supply remotely through a serial port

connection (standard feature).

• GPIB: Where the user operates the supply remotely through the faster General

Purpose Interface Bus. The GPIB bus follows the IEEE 488.2 standard and is an optional feature of this power supply.

• Multichannel: Where the user operates the supply remotely through the

optional multichannel link between 2 or more (up to 50) power supplies (optional feature).

• Analog: Where the user operates the supply remotely through the isolated

analog programming and readback port (standard feature). Three options are available:

• Analog V and I

• Analog V

• Analog I

Each of these methods is referred to as a control mode.

Load Wiring

When connecting load wiring to the power supply, consider the following factors:

• Current carrying capacity of the wire

• Maximum load wiring length for operation with sense lines

• Noise and impedance effects of the load lines

Current Carrying Capacity

As a minimum, load wiring must have a constant capacity greater than the output current rating of the power supply. This ensures that the wiring will not be damaged even if the load is shorted. Table 2.4. shows the maximum current rating, based on 450A per square centimeter, for various gauges of wire rated for 105°C operation. Operating at the maximum current rating results in a temperature rise of approximately 30°C for a wire operating in free air. Where load wiring must operate in areas with elevated ambient temperatures or bundled with other wiring, use larger gauges or higher temperature-rated wiring. For high current applications, custom-designed bus bars are typically used. To increase the current carrying capability, use parallel cables.

Effects

For applications using remote sensing, or for improved voltage regulation at the load, you must limit the voltage drop across each load line. We recommend that you use the larger load wiring to ensure a smaller voltage drop (1V maximum), although units will compensate for up to 5V drop in each line with the remote sense lines connected.

To minimize noise pickup or radiation, use the shortest possible length of shielded-twisted pair wiring for load lines. Connect the shield to the chassis via a rear panel mounting screw. Where shielding is not possible or is impractical, twisting the wires together offers some noise immunity. When using local sense connections, use the largest practical wire size to minimize the effects of load line impedance on the regulation of the supply.

Load Connections

WARNING

Exercise caution when operating the power supply. High energy levels can be stored at the output terminals on a power supply in normal operation. In addition, potentially lethal voltages exist in the power circuit and on the output and sense connectors of a power supply with a rated output greater than 40V. Filter capacitors store potentially dangerous energy for some time after power is removed.

CAUTION

When making connections to the bus bars, ensure that each terminal’s mounting hardware and wiring assembly are placed to avoid touching the other terminal and shorting the power supply outlet. Heavy connecting cables must have some form of strain relief so they don’t loosen the connections or bend the bus bars.

Make load connections at the rear of the power supply at the positive and negative output bus bars or to the 4-terminal wire clamp connector, depending on the model. (See Figure 2.7.)

Wire Size The wire should be one size larger than necessary to accommodate the required

output current. Normally, the next largest commonly used gauge is used. For example, use 10AWG for 20A, and 8AWG for 30A.

Isolation The wire must have a suitable insulating coating that will prevent arcing between the

positive and negative output current, and must be rated for 105

Load Connections

Single Load To connect a single load to the DC output bus bars (10–150V outputs):

1. Ensure that the power supply is powered OFF.

2. Place a bolt in the connecting hole of the negative bus bar, and fasten the negative wire or bus bar, a washer, and a nut to the bolt.

3. Using a wrench, turn the bolt until it is secure at approximately 25 foot-pounds (34Nm).

4. Fasten the positive wire or bus bar to the positive bus, using a bolt, washer, and nut.

5. Tighten the bolt to approximately 25 foot-pounds (34Nm).

6. Ensure that the positive and negative wires are arranged so bare wires do not come into contact with each other or the chassis.

To connect the DC output wire clamp connectors (300V, 600V outputs):

• Connect appropriately sized wires as described in steps 1 to 6 above, except strip

0.5 in. (14mm) of insulation off each load wire, and clamp in the output connector by securely tightening the vertical clamp screw for each output.

Multiple

Loads

To connect multiple loads in parallel:

• Follow the “Single Load” procedure with the following exception:

• To minimize interaction between loads, bring the wiring for each load directly

back to the supply output. When each load to the power supply is wired separately, the loads will see only the precisely regulated output from the supply. If 2 loads share a single cable, the fluctuation in current to one load will cause the voltage to vary on the others. This is due to wire impedance drops.

Remote Sensing

The power supply regulates the output voltage at the output connectors in its normal configuration without remote sense lines connected.

Remote sensing lets the power supply track and regulate the output voltage at the load, and thereby compensate for the voltage drop in the load lines. The power supply will only compensate within the limitations of its voltage rating, to a maximum of 5V per load line. Remote sensing is normally only required for critical loads which cannot tolerate the slight voltage drop in the load lines caused by their resistance. Remote sensing has no effect when the power supply is operating in Constant Current mode.

Two remote sensing connectors are located on the rear panel of the power supply. See “Rear Panel” on page 30 for location and polarity. Connect 2 wires from these ports to the load, where the power supply cables terminate for your connection. Carefully observe the correct polarity when making the connection. On 12000 Watt units, connect the sense wires to the connector on the top or master power module.

The remote sensing input is sensitive to electrical noise, so always use a shielded twisted pair, 22AWG or greater for the sense line cable. Terminate the shield to the supply chassis or the negative output of the power supply for best results.

Shutdown

In this state, the output is disabled and there is no output regardless of power settings. The power supply can be placed in the Output Shutdown state by a command (via the front panel or from the programming interface), via the Interlock signal, or from a protection mechanism. This is also called the Standby mode.

Soft Start In this state, the output power is ramping up gradually towards its target load. This

reduces equipment stress. This state occurs whenever the supply output is set to ON or a protection state is re-set, and is approximately 2 seconds in duration.

Control

Knobs

The Voltage and Current knobs are the simplest way to control the power supply.

The Voltage and Current knobs are digital encoders, and therefore, there are no start or end points to their rotation, and their rotation positions are meaningless when the power supply is powered OFF. The control knobs can be disabled through a menu command. See “Lock Out Control Knobs” on page 98 for more information.

Use the OUT ON/OFF toggle key to enable or disable the power supply’s output. When the output is disabled, the voltage and current at the output are zero regardless of the setpoints.

When the output is on and you press OUT ON/OFF, OUTPUT OFF is momentarily displayed. Then the readback is 0000V 0000A to indicate that output is zero, and the OUT OFF annunciator illuminates. This is also known as Standby mode.

When you press OUT ON/OFF again, the OUT ON annunciator illuminates and the power supply resumes normal operation, with the display showing a readback of the output.

Seven configurable protection mechanisms are available:

OVP shuts down the power supply if the protection limit is exceeded. The other options offer a choice: they shut down the power supply or issue a warning. When the protection level is set to zero, that mechanism is considered disabled. However, in the case of OVP, a hardware protection mechanism still exists.

The last protection mechanism is Fold Mode protection, when the unit will shut down if it enters the selected regulation mode for a specified period of time.

Other protection mechanisms designed to protect the power supply are:

• AC Off: AC Off protection will disable the output if the AC line drops below

The power supply can be controlled locally with the front panel or remotely through several different interfaces. The remote interfaces are discussed in Section 4, “Remote Operation”, Appendix B. “SCPI Command Reference”, and Appendix D. “GPIB”.

The factory default remote control setting is RS-232. It has a default configuration of 9600 baud.

The LCL/RMT key allows you to shift between local and remote control.

To shift from local to remote control:

The AUTO SEQ PGM menu option is used to set up command programs for automated operation. There are 10 programmable sequences with up to 99 steps per sequence.

Each sequence can be repeated a programmable number of times or forever. If the sequence contains steps that advance by a trigger event, a single trigger source can be selected to advance those steps.

Each step can be programmed to set the voltage setpoint, current setpoint, power setoint, and OVP level automatically. Each step can also be programmed to advance by a delayed time or a trigger event. The duration of each step may range from 10 ms to 99 hours.

Using Auto

Sequencing

Auto Sequence programs can be set to run as a Power ON default or recalled from memory by pressing the RECALL key. In Auto Sequence mode, 3 of the function keys operate as alternates:

• VOLTAGE operates as RUN/PAUSE.

• CURRENT operates as TRIGGER.

• STORE operates as END.

In the following discussion about running programs in Auto Sequence mode, each of the keys mentioned above is referred to as their alternate function.

When an Auto Sequence program is launched from Recall, the AUTO SEQ annunciator illuminates on the front panel. Press EXIT to return the unit to normal operating mode.

Auto sequence programs can operate 3 different ways:

• They can run automatically through a series of steps, repeating those steps a

pre-set number of times if necessary, and complete their operation without intervention from an operator.

• They can run automatically and be paused. If you need to stop the program

temporarily, you can press PAUSE to stop it, and then press RUN to resume the program’s operation when ready. When a sequence is manually paused, the Pause annunciator is illuminated. (The output remains on and voltage may be present at the output.)

• They can run automatically programmed to wait for a trigger at certain points in

the sequence. If you want the program to resume, you can press TRIGGER or supply a trigger signal to the rear panel Trigger input. When a sequence is paused by a trigger, the Trigger? annunciator is illuminated.

During operation, press the Up key to display information on the currently running sequence including sequence number, step number, step parameters (settings), the trigger source, as well as the loop count.
