Tektronix PS280 Service & Reference Guide

#%f%M_rLTLn Product Description
This subsection begins with a general description of the PS280 or PS283
Power Supply. The Specifications subsection immediately follows.
General The Tektronix PS280 or PS283 Laboratory DC Power Supply is a multifunction
bench or portable instrument. This regulated power supply provides a fixed 5 V
output for powering logic circuits and two variable outputs for a wide variety of
test and experimental uses. The PS280 or PS283 can be used in any applica-
tion where three independent power supplies housed in a single package
represent a convenience.
The PS280 or PS283 contains two identical, independently adjustable DC
power supplies that you can vary from 0 to 30 V. The current on the PS280
variable power supplies varies from 0 to 2 A. The current on the PS283 vari-
able power supplies varies from 0 to 1 A. In all other respects the instruments
are identical. Unless otherwise noted, descriptions and procedures in this
manual apply to both instruments.
Front panel switches select one of three modes of operation: independent,
series, or parallel. In the independent mode, the output voltage and current of
each supply can be controlled independently. In the two tracking modes, the
variable outputs are connected either in series or in parallel. Under these
circumstances, the controls of the master power supply adjust the voltages or
current of both power supplies. Series mode allows the power supplies to be
varied from 0 to 60 V at 0 to 2 A for the PS280, or 0 to 1 A for the PS283.
Parallel mode allows the power supplies to be varied from 0 to 4 A for the
PS280 at 0 to 30 V, or from 0 to 2 A at 0 to 30 V for the PS283.
