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.

x Operating Manual for XT Series Power Supply

Section 1. Features and Specifications

Introduction

The XT Series of linear, regulated DC power supplies provides reliable, high
performance solutions for a broad range of laboratory, development and system
applications. The series consists of seven basic models that may be purchased as
single units or combined as dual, triple, or quadruple configurations containing any
combination of models. (See the chart below for a list of available models.)

Low output noise and ripple, excellent line and load regulation, and a wide variety
of options, including analog, RS232 standard, or IEEE-488 controlled programming,
make the XT Series the first choice in flexible DC power system design.
