#About OF-PSU-B

These linear precision power supply modules provide an output power of 45 W per output for symmetrical output voltages up to 1 kV. They are characterized by extremely low noise voltages as well as very low residual ripples of less than 1 ppm.

The output voltages can be set to a value between 0 and nominal voltage by a 25-turn potentiometer. The power supplies are equipped with an electronic current limiter and surge protection. They are cooled by an external heat sink.
