INTRODUCTION

Congratulations on your purchase of a very versatile power supply. The XP-4 has been designed to
give you years of trouble-free performance if used properly.

The Model XP-4 features four solid state DC power supplies. All internal DC power modules are UL
approved for your safety. The first supply has a variable output from 0 to 12 volts at 0.5 amperes. The
second supply has a fixed output at 12 volts and 0.5 amperes. The third supply has a fixed output at
5 volts and 1 ampere. While the fourth supply has a fixed output at –5 volts and 0.25 amperes. All
four supplies are fully protected from short circuiting their outputs. All supplies are fully regulated with
special circuits that keep the output voltages from changing when the current changes from 0 to rated
output. This supply is ideal for use in school labs , service shops, design labs, or an ywhere precise DC
voltages are required.

OPERATING INSTRUCTIONS

1. Check the voltage rating of the equipment to be powered.

2. Plug the power line cord on the XP-4 into a 120V, 60Hz AC outlet.
