SERIES PS300 SPECIFICATIONS
General Information
The PS300 series are programmable precision high voltage power supplies for use in laboratory or test
applications. They feature reversible polarity, excellent regulation and low output voltage ripple. The digital
displays provide accurate readings of voltage and current. Also, digital entry of the current and voltage
provides accurate resettability. Output voltage can be set from either the front panel, the remote analog voltage,
or over the optional GPIB interface. Voltage and current signals are also available for remote monitoring.
