High Voltage Modules

The HV-modules made by m-u-t are designed for driving Avalanche photodiodes, photomultiplier, laserdiodes, piezo actors and similar products which require operating voltages up to 3 kV.

High precision Output voltage control
Depending on the selected HV-module, the output voltage can be adjusted from 50 V to 3 kV either positive or negative. With the short circuit resistant output voltage monitor, the output voltage can be controlled within limits of ± 0.1%. This high stability of the output voltage ensures precise operation of the connected devices.

Short Circuit resistant output current
The output current is limited to 0.2 mA or 1mA. To protect the HV-module and the electronic unit against short circuits, the output current is limited to 103% specified max current for all HV-modules.

Temperature compensation for APDs
Avalanche photodiodes require a temperature compensation for perfect operation. m-u-t offers a modified HV module for that purpose, integrating a temperature compensation circuit. These ABC-modules come with an external SI-temperature sensor, and they also can be operated with temperature sensors which are installed inside the APD module.
