Important Safety Instructions

Before applying power to the system, verify that your product is configured properly for your particular application.

WARNIN

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.

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.

The equipment used contains ESD sensitive parts. When installing equipment, follow ESD Safety Procedures. Electrostatic discharges might cause damage to the equipment.

Operating Manual for XHR Series Power Supply

Section 1. Features and Specifications

Description

The 1000 watt DC output power supplies provide low noise, precisely regulated, variable DC output. Typically they are used for bench and automated test equipment (ATE) applications. Each unit includes over voltage protection and thermal shutdown as standard features. Universal AC input allows you to use line voltages globally without resetting switches or adding options. Built-in power factor correction gives you full output power from low current/low voltage outlets, reduces power line interference, and allows you to meet international regulations.

You can select from several remote control choices for either analog or digital control. For analog control, choose from standard analog control or optional 4-channel isolated programming. Digital control options include RS-232 control or GPIB programming. You can use the power supply on your benchtop or rack mounted; each supply occupies less than 3-1/2 in. (2 U) of vertical space.

The output terminals for the low voltage models (7.5 V to 40 V) are bus bars. The high voltage models (60 V to 600 V) use a wire clamp connector. See Figure 1.2 and Figure 1.3 to identify the switches and connectors on the rear panel.

Use the SW1 Programming, Monitoring, and Shutdown Select switch and the J2 Programming, Monitoring, and Sense connector to choose among several remote programming and monitoring options. See the following sections for more information about remote programming:

The SW1 Programming, Monitoring, and Shutdown Select switch is an 8-position piano DIP switch located on the power supply’s rear panel. The SW1 switch enables you to choose:

• Output voltage and current limit programming scales

• Output voltage and current monitor scales

• Remote shutdown circuit logic

• Resistive programming of output voltage or current limit

• Over temperature shutdown mode

The power supply is shipped with the SW1 switch set in the default operating configuration, as illustrated in Figure 1.4.

Resetting the Switches The rear panel is labelled with OFF at the top of the

switch and ON at the bottom. Any of the eight switches on SW1 is OFF (OPEN) when it has been flipped up to break contact, ON (CLOSED) when flipped down to close contact.

Before making any changes to the switch settings, disable the power supply output. Either turn OFF the supply, or place the supply in shutdown mode by pressing the front panel STANDBY button to its ON position. Once output is disabled, use any small, straight-bladed screwdriver to change the switch settings.

The J2 Programming, Monitoring, and Sense connector is a 12-terminal wire clamp connector located on the power supply’s rear panel. The J2 connector provides access to the following functions:

• remote programming of output voltage and/or current limit

• remote monitoring of calibrated readback signals for output voltage and output

current

• remote control of the shutdown function using 2.5-15 V or TTL-compatible

signals

• remote sensing of output voltage

Making J2 Connections

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 J2 connector.

CAUTION

Do not attempt to bias the Program/monitor signal return (J2-6) relative to the power supply output return, as they are connected internally. Use the Isolated Programming (ISOL) option for control from programming sources at potentials differing from the supply output return.

Wire Clamp Connector Screw

Make connections to the J2 connector using its screw-type wire clamps. Before making any connections, turn the power supply OFF and wait until the front panel displays have gone out. You can unplug the connector from the back of the unit in order to make it easier to install the required wiring.

Wiring

WARNING

There is a potential shock hazard at the output and J2 terminals 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, 105 °C, 600 V wiring for use with a 600 V, 1.7 A model power supply

For lowest noise performance, make connections to the J2 connector with either

individually or group shielded 18-22 AWG (0.3-0.8 mm

) wire. Maintain the shield to within 1.5in. (40 mm) of the end of each wire. Strip 0.26.in (6.5 mm) of insulation, insert into the correct terminal, and tighten the wire clamp. You must ground the shield(s) to the power supply chassis with a connection less than 1.5.in (40 mm) long.
