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.

Section 1. Features and Specifications

Description

This series of power supplies provides highly stable, variable DC output voltage and current at 3000 Watts of output power. You can select from several remote control choices: standard analog programming, optional isolated programming or readback, and optional GPIB programming or RS-232 control. It is designed for a broad range of development, system and burn-in applications and uses high frequency switching regulator technology to achieve high power density in a small package size. See

Table 1.1. for the list of available models.

with the optional ISOL Interface.

• Optional internal GPIB control for remote digital programming and readback

from a computer.

• Front panel push button control of Output Standby Mode, OVP reset,

Remote/Local Programming Mode selection and preview of voltage, current and OVP setpoints.

• Optional bus bar cover may be purchased as there may be a high voltage issue

for benchtop units operating above 42 Vdc.
