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 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.
