Safety

Warnings,

Cautions,

and Notes

Warnings, cautions, and notes are defined and formatted in this manual as shown

below.

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.

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.

Section 1. Features and Specifications

Description

The internal GPIB interface card allows you to operate your power supply from a

computer controller via the IEEE-488 communications bus. See Figure 1.1, “Sample

Configuration using GPIB Interface”.

The GPIB interface allows complete remote programming of your power supply,

including status reporting, settings query, and interrupt generation with

user-designated fault conditions. Both the voltage and current output are precisely

programmed directly in volts and amps with 16-bit resolution. Additionally, the

built-in DVM and current shunt measure the actual power supply output and provide

you with 16-bit readback. The programming command set is easy-to-use and

includes software calibration commands. The interface card comes standard with

several protection features such as programmable over voltage protection, foldback,

load isolation signal, and soft limits.
