Features:
■ Constant voltage (CV) and constant current (CC)
operation
■ Independent or series tracking/parallel mode operation to
double voltage or current
■ Coarse and fine voltage controls
■ Adjustable current limiting
■ Designed to operate continuously at rated output
■ Overvoltage protection and reverse polarity protection
The 1760A series triple output DC power supplies offer three
independent outputs with coarse and fine adjustment knobs for
volts. The 4-digit LED display offers 10 mV and 1 mA
resolution, providing the capability to set voltage and current
values more accurately than 3-digit displays found in most
comparable power supplies.
