FEATURES

Low ripple and low noise characteristics

Ripple and noise are kept extremely low by use of the series regulator method, and excellent electrical characteristics are provided.

Simultaneous display (voltage and current)

Using 3-digit LED, voltage and current can be set and confirmed simultaneously.

Floating output terminals

Floating output terminals is provided for either positive or negative ground.

Series/parallel operation (only for PAC-R series)

The output voltage can be increased by series operation, while output current can be increased by parallel operation.

Remote sensing terminal (only for PAC-R series)

PAC-R power supply can monitor the voltage at the load and stabilize voltage at the load.

Remote control terminals (only for PAC-R series)

Remote control terminals on the rear panel can be used for control of output voltage and current by external resistance or voltage.
