Precision Model 1601 Regulated DC
Power Supply is a versatile, laboratory quality in-
strument which provides regulated dc voltage and
current outputs of 0 to 50 volts and 0 to 2 amperes
respectively. Its high specifications, operating ease,
and special features make it an excellent choice
for most applications requiring a dc power source.
It is especially well suited for powering transis-
torized and fully solid state electronic equipment
such as automobile radios and sound systems, bat-
tery operated radio receivers, portable radios,
mobile citizen’s band transceivers and Walkie-Talkie
transceivers.
The following list is ‘but a small sample of the
most popular applications for the instrument:
-Service Technicians
-Factory Technicians
-Engineers and
Laboratory
