Warnings
and
Cautions
Warnings and cautions are defined and formatted in this manual as shown below.
Power
Supply
Safety
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.

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
• 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.
• Active Power Factor Correction (PFC) delivers lower input current and input
current harmonics.
• Ten-turn voltage and current controls permits high resolution setting of the
output.
• The automatic crossover system allows the power supply to automatically
switch operating modes between current or voltage mode.
• Multiple units can be connected in parallel or series to produce greater diversity
or for use in high precision applications.
• Short-circuit-proof power outlets give greater operating safety.
• 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.

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:
• Remote programming of both output voltage and current
• Calibrated readback signals for remote monitoring of output voltage and output
current
• 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.

1. The TTL shutdown circuit is isolated to 500 V from the power supply output and chassis.
2. Jumpering pins J210-6, J210-7, and J210-8 will select both remote output voltage
programming and remote output current limit programming.

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.
