The HM24 Series is a family of ultra low noise, high voltage, high performance power supplies. Analog programming and monitor outputs for output voltage and output current are provided.

Output can be controlled by using either an external control voltage or external potentiometer. A very low noise reference voltage output is available. The output voltage is directly proportional to the programming voltage. It features outstanding linearity.

Load regulation is excellent and the output voltage is independent from the input supply voltage. The output is not isolated. High voltage return is internally connected to ground (GND).

The power supply modules are protected against arc and short circuit.
