WARNING—High Energy and High Voltage |
|
Safety |
|
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 LV 1kW Series Power Supply |
Section 1. Features and Specifications
Description
This series of power supplies provides highly stable, variable DC output voltage and current at 1000 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.
