Specifications

These linear-regulated DC power
supplies provide reliable and
convenient DC power on a lab
bench. Voltage and current can be
monitored simultaneously on the
front panel meters. There is also an
overload indicator for each output.
E3620A
The E3620A has two isolated,
independent, CV/CL 25 volt
outputs. It is easy to make precise
adjustments using the 10-turn pots.
E3630A
The E3630A triple output power
supply has two 20 volt outputs and
one 6 volt output. The +6 V output
is an isolated constant-voltage/
current-foldback output, and both
the +20 volt output and the -20 volt
output are constant-voltage/current-
limit. An autotracking feature lets
you use one voltage control to adjust
both 20 volt outputs. These outputs
track each other to within one per-
cent, making it easy to adjust the
power supply for circuits requiring
balance voltages. The ±20 volt
outputs are referenced together
to a floating common.
