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 user’s 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

•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.

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:

•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.

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.
