SAFETY SUMMARY
This power supply contains high voltage and current circuits that are potentially lethal.
Because of its size and weight, electrical and mechanical stability must be ensured. The
following safety guidelines must be followed when operating or servicing this equipment.
These guidelines are not a substitute for vigilance and common sense. If this power supply is
not used as specified in this manual, the protection provided by this equipment may be
impaired. California Instruments assumes no liability for the customer's failure to comply with
these requirements.
BEFORE APPLYING POWER
1. Check the units input rating on the type label and verify the correct voltage is applied to the unit
(for example 208 V L-L, 3 Phase).
2. The chassis and cabinet of this power supply must be grounded to minimize shock hazard. A
chassis ground is provided at the input terminal block. This is located at the back of the cabinet
on the right hand side (looking at the back of the unit). The chassis ground must be connected
to an electrical ground through an insulated wire (green/yellow) of sufficient gauge.
3. The XDS Series power supplies do not have internal AC mains disconnect. Instead, protection is
provided by fuses. The on/off button only engages or disengages the bias supplies, it does not
disconnect the AC mains to the unit. It is strongly recommended to use a suitably rated
circuit breaker or mains disconnect device with branch protection rating per local
electrical codes between point of connection and the XDS unit AC input.
FUSES
Use only fuses of the specified current, voltage, and protection speed.
DO NOT OPERATE IN A VOLATILE ATMOSPHERE
Do not operate the power supply in the presence of flammable gases or fumes. This product is
designed to operate in a controlled environment. Do not expose to rain or snow.
DO NOT TOUCH ENERGIZED CIRCUITS
Disconnect the power cable before servicing this equipment. Even with the power cable disconnected,
high voltage can still exist on some circuits. Discharge these voltages before servicing. Allow at least
30 minutes for all internal circuits to discharge before removing the top cover. Only qualified service
personnel may remove covers, replace components or make adjustments.
DO NOT SERVICE ALONE
Do not remove covers, replace components, or make adjustments unless another person, who can
administer first aid, is present.
DO NOT EXCEED INPUT RATINGS
Do not exceed the rated input voltage or frequency. Additional hazards may be introduced because of
component failure or improper operation.
DO NOT MODIFY INSTRUMENT OR SUBSTITUTE PARTS
Do not modify this instrument or substitute parts. Additional hazards may be introduced because of
component failure or improper operation.
MOVING THE POWER SUPPLY
When moving the power supply, observe the following:
1. Remove all AC power to unit.
2. Note that the handles are provided to pull instrument out of 19" instrument cabinet and are
not designed to support the weight of the unit.
3. Use two people to prevent injury.
SURFACE STABILITY
Operate the power supply only on a level surface.

10 XDS Series
1 Introduction
1.1 General Description
Figure 1-1: XDS Series DC Power Supply
The Argantix XDS Series of DC Programmable Power Supplies are designed specifically for
laboratory test and systems applications requiring single output, variable DC voltage and current
with good ripple and regulation characteristics. The XDS Series comes in a 3U chassis and can
operate in constant current or constant voltage mode with auto crossover feature. Available
Power levels are 5kW, 10kW and 15kW.
Simple front panel controls enable the voltage and current limit to be changed. Measurements of
voltage, current, peak current and power can also be read from the front panel LED displays.
The front panel contains a output on/off button for controlling the DC supply output and an LED
indicator that informs the operator of the output status at all time.
The left hand side LED display is used to display the programmed voltage as well as the
measured output voltage. The LED display to the right is used to program the current or to
display measured current, peak current or power. The display SELECT button can be used to
set the desired display mode.
A standard RS232C and optional IEEE 488 interface is available for applications that require
remote control and measurements. While operated remotely, the front panel can be locked out
and the remote control status is indicated by a REMOTE LED.
A power on/off switch can be used to turn the DC supply on or off.
Note: This user manual applies to the XDS models series II with the 5005-720-1
controller assembly. For first generation XDS DC models with controller
assembly 5005-708-1, refer to user manual P/N 5005-980 instead. First
generation XDS models typically do not have the air vents in the front
panel.

User and Programming Manual
XDS Series 11
1.2 Bench Top use
The XDS Series DC Supply may be used as a bench top unit provided adequate provisions are
made to protect the end-user from touching the output terminals. To this end, output covers are
provided on all XDS units. These covers must be installed during use and may only be removed
when the unit is not in use and disconnected from AC mains.
Adequate air flow must be maintained at all times so care should be taken not to block the front,
top and side air intakes or the rear air exhaust. Leave at least 4" of clearance at the back of the
unit to allow proper airflow.
1.3 Equipment Rack use
The XDS Series uses a 19" cabinet with rack ears and can be installed in a standard equipment
rack. Due to the weight of the unit however, it must be properly supported by either a shelf or L
brackets on both sides. The rack ears are not designed to support the full weight of the XDS unit
when installed in a cabinet but only to prevent it from sliding out.
Contact Argantix customer support ([email protected]) for information on rack mount kits for
specific cabinets depths.
Proper airflow must be maintained in the instrument cabinet and the rear of the cabinet should
not be closed off by a door but rather a perforated screen allowing adequate airflow. It is also
important to leave enough clearance above each unit as some of the air intake is on the top
cover.
Note: For optimal cooling, it is recommended to leave a 1.75" (1 U) space above
each XDS unit.
This space may be covered by a louvered cover plate to allow some air intake from the front of
the cabinet. When planning cabinet space, allow for 4U per DC supply.
If insufficient rack space is available, the top vents may be blocked off by stacking units directly
on top of each other but maximum power may not be available at maximum ambient temperature
due to over temp fault.

2.9 Parallel Operation
Two or more XDS power supply of the same model number (voltage range and power level must
match) may be combined to create a higher power system. This requires one master unit
(default) and one or more auxiliary units (-AUX).
The maximum number of XDS units that can be paralleled is 5 (1 master + 4 auxiliary units).
The following specifications apply to multi-box XDS configurations:
Parameter
Current Range: Multiply by number of XDS units.
Current Programming:
Accuracy: Multiply by number of XDS units.
Resolution: Same as single XDS unit.
Current Sharing Within 2 % of combined current range.
Current ripple Multiply by number of XDS units

2.10 Factory Configuration Options
All XDS models can be factory configured with the options shown below. Configuration changes
can be made in the field if needed. Refer to Chapter 5 for details on changing configuration
settings.
Option Configuration
none Stand-alone and Master operation.
-AUX Auxiliary configuration. Can be used with Master XDS unit to increase
power level.
-RPV10 Stand-alone operation with analog voltage programming, 0 – 10 V.
-RPV5 Stand-alone operation with analog voltage programming, 0 – 5 V.
-RPC10 Stand-alone operation with analog current limit programming, 0 – 10 V.
-RPC5 Stand-alone operation with analog current limit programming, 0 – 5 V.
2.11 -LC Option
The –LC option reduces the output capacitance of each DC power module. This results in
improved rise and fall times compared to a standard XDS unit. The output noise and ripple
specification is increased by a factor of 2 when adding the –LC option. This option is available
only on models with voltage ranges of 100V and below. The –LC option must be ordered at time
of initial orders. This option cannot be retrofitted.
-LC Option Output capacitance with LC option
