Safety

Warnings, cautions, and notes 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.

Note

Describes additional operating information which may affect the performance of the equipment.

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.

Operating Manual for XPR Series Power Supply

Section 1. About The XPR Power Supply

Overview

The XPR Series of programmable DC power supplies is designed for use in OEM, ATE, burn-in, magnet charging, and other high power systems for a broad range of applications. The XPR uses “Soft Switching” technology which provides superior performance combined with a high level of user control through both front panel and remote interfaces.

Features and

Options

• Zero voltage (soft) switching for low noise output, improved efficiency and

higher reliability

• Active Power Factor Correction (PFC) for lower input current draw and lower

current harmonic generation

• Remote voltage sense with 5V line drop compensation

• Automatic Voltage/Current mode crossover

• Remote interlock

• 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.

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

current, or OVP setpoints. Front panel light emitting diode (LED) indicators for voltage and current mode operation, OVP, remote programming mode, and shutdown. Front panel control of OVP.

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

current or voltage.

• Over Temperature shutdown, latching or auto reset.

• 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

isolated readback of output voltage and current with the optional ISOL Interface.

• CSA Certified to UL 3111-1, CSA 1010.1; CE Mark; FCC Class A

The S1 Programming, Monitoring, and Interlock select switch is an 8-position piano DIP switch located on the power supply’s rear panel. See Figure 1.4. The S1 switch enables you to choose:

• Resistive programming of output voltage or current limit

• Output voltage and current limit programming scales

• Output voltage and current monitor scales

• Remote shutdown circuit logic

• Over temperature shutdown mode

Resetting the Switches

Before making any changes to the switch settings, either turn off the AC power switch or disable the power supply output by pushing the front panel OUT ON/OFF switch to its IN position. This temporarily shuts down the power supply. The front panel OFF LED turns on. Then use any small, flat-bladed screwdriver to change the switch settings.
