Power supply for MPPC^®
C11204-01
Bias power supply with built-in high precision
temperature compensation for MPPCs
The C11204-01 is a high voltage power supply that is optimized for MPPCs (multi-pixel photon counters). It can output up to
90 V. It contains a temperature compensation function that constantly optimizes the MPPC operation even in environments
with varying temperatures. It also has built-in output voltage monitor and output current monitor. All functions can be con-
trolled from a PC via its serial interface (UART).
Features
Wide output voltage range: 50 V to 90 V
Low ripple noise*¹: 0.1 mVp-p typ.
Superb temperature stability: ±10 ppm/°C typ.
Finely adjustable resolution (in 1.8 mV steps)
Serial interface
*1: No load, using the recommended circuit
