*2: Using the recommended circuit

*3: To control the C11204-01 from a PC, we recommend that you use the C12332 driver circuit (starter kit) for MPPC

(sold separately, C11204-01 built in).

*1: No load, using the recommended circuit

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).
