Safety

Warnings and cautions are defined and formatted in this manual as shown below.

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.

vi Operating Manual for XHR Series Power Supply

About This Manual

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. Whether you are powering batteries, development circuits, and magnet coils or running ATE systems, the power supply provides the precision and power that you need.

Features and Options

• Models available with voltage ranges from 0-7.5 Vdc to 0-600 Vdc; current

ranges from 0-1.7 A to 0-130 A.

• Internal power factor correction allows operation from a standard 120 Vac, 15 A

outlet.

• Thermal shutdown, latching or auto reset.

• Front panel control of Over Voltage Protection (OVP).

• Simultaneous digital display of both voltage and current.

• Ten-turn front panel voltage and current controls for high resolution setting of

the output voltage and current from zero to the rated output.

• Automatic mode crossover into current or voltage mode.

• Front panel push button control of output standby mode, and preview of voltage,

current, or OVP set points. Front panel LED indicators for voltage and current mode operation, OVP, remote programming mode, and shutdown.

• Multiple units can be connected in parallel or in series to provide increased

current or voltage.

Revision A 15

Features and Specifications

Front Panel Controls

• Remote analog voltage and current limit programming with selectable

programming ranges.

• External monitor signals for output voltage and current.

• Isolated analog remote programming control of the output voltage or current and

Features and Specifications

Rear Panel Connectors and Switch

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.
