The miniature high-voltage dBC (digital bias controller)-series modules are particularly well suited for controlling avalanche photodiodes and fast PIN photodiodes. We have three versions available:
| Version | Output Voltage | Operating Voltage |
| dBC-120-3V | 1V-120V | 3V |
| dBC-220-3V | 1V-220V | 3V |
| dBC-380-5V | 1V-380V | 5V-12V |
All versions have an extremely compact design and nickel-plated metal 21mm x 21mm x 10mm housings. In addition, the temperature coefficient of the output voltage can be precisely adjusted to match the properties of the corresponding APD. Discrete APDs or APD modules can both be operated, even with an integral temperature sensor.
The output current is limited to a safe maximum value of 0.8mA to effectively protect the APD from overloading. The output voltage is adjusted either by analogue or digital control using a programming interface for the microcontroller.
