Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNIN
G
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
WARNIN
G
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance
equipment must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the userâs application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must
ensure that the output power lines are labeled properly as to the safety hazards and that any
inadvertent contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury,
loss or damage that results from improper use of the equipment and accessories.

Section 1. Features and Specifications
Description
The XPD Series of DC power supplies provides stable, variable output voltage and
current for a broad range of development and system requirements. The units use
high-frequency soft-switching technology to achieve high power density and retain
a small package size. They feature a built-in analog programming interface, with
optional RS-232 and IEEE-488 controlled programming, making this series the first
choice in flexible power system design. See Table 1.1 for the list of available models.
Table 1.1 500 Watt Series Models
Features and Options
â˘The power supply delivers simultaneous digital displays for both voltage and
current, and bar graph displays for monitoring transient changes, which gives the
user the benefit of continuous, up-to-date information.
â˘Active Power Factor Correction (PFC) delivers lower input current and input
current harmonics.
â˘Ten-turn voltage and current controls permits high resolution setting of the
output.
â˘The automatic crossover system allows the power supply to automatically
switch operating modes between current or voltage mode.
â˘Multiple units can be connected in parallel or series to produce greater diversity
or for use in high precision applications.
â˘Short-circuit-proof power outlets give greater operating safety.
â˘A built-in Analog Programming (APG) Interface provides analog signal control
of voltage and current, overvoltage protection (OVP), master/slave output
tracking, and remote ENABLE/DISABLE for safety and precision.

J210
Connector
The J210 Analog Interface connector is a 15-pin female DSUB connector located on
the rear panel. See Figure 1.6. Use the J210 programming, monitoring, and
shutdown 15 pin DSUB connector for remote programming and monitoring
functions. See Figure 1.2 for the location of the J210 connector at the rear panel. We
recommend that you mate the J210 connector with a 15-pin male connector, such as
a Tyco 747908-2 or equivalent.
The J210 connector provides access to the following functions:
â˘Remote programming of both output voltage and current
â˘Calibrated readback signals for remote monitoring of output voltage and output
current
â˘Isolated remote shutdown function using a 5-15 V signal
See Figure 1.6 for a graphic presentation of the J210 connector and its pinouts.

Making J210
Connections
Wiring
For most connectors and jumpers, use any suitable wire such as 16 to 24 AWG
stranded wire. For lowest noise performance, use shielded pair wiring of 16 to 24
AWG. Use the shortest leads possible. Ground the shield to pin 8 (auxiliary ground)
on the J210 connector or to the chassis via one of the J210 connector screws.
!
CAUTION
Program/monitor signal and return are internally connected to the power
supply negative output. Do not attempt to bias these away from that
potential.
!
CAUTION
To maintain the isolation of the power supply output and prevent ground
loops, use an isolated (ungrounded) programming source when operating
the power supply via remote analog control at the J210 connector.
!
CAUTION
Before making connections from external circuits to the J210 connector, turn
the power supply OFF and wait until the front panel displays have gone out.
WARNING
There is a potential shock hazard at the output when using a power supply
with a rated output greater than 40 V. Use load wiring with a minimum
insulation rating equivalent to the maximum output voltage of the power
supply. For example, select TEW, 105 °C, 300 V wiring for use with a
120 V, 4.5 A power supply.

Electrical Specifications
These specifications are warranted over a temperature range of 0 °C to 50 °C
with local sense. Above 50 °C, derate output linearly to zero at 70 °C. Nominal
line voltages are 100/120/200/230/240 Vac. Specifications and characteristics
refer to a single output model unless otherwise stated, and specifications apply
to either front or rear outputs unless noted.
