Introduction; Controls And Indicators - BK Precision 1601 Instruction Manual

The B & K 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

Controls and Indicators

Measures actual output load
current during normal oper-
ation.
Indicates current limit value
when set/reset button 4 is
pushed.
Selects range for current
meter 1 and coarse setting
of current limit. Full scale
meter reading and maxi-
mum current limit of:
0.05 ampere (50 milliamps)
