HIGH VOLTAGE
POWER SUPPLY
C12446 SERIES
The C12446 series is an on-board type high voltage power supply module, especially designed for photomultiplier
tubes. This power supply can drive several photomultipliers used for multi-channel measurement. The design offers good performance and complete fail-safe protection.
FEATURES
●High output power (1 kV / 10 mA)
●Compact and lightweight
●High voltage and current monitor output
●Low Ripple / Noise

* The instability in the external controlling voltage should be
minimized as it directly affects the output voltage quality.
** Never connect the pin number 2 and 4 directly and
externally.
NOTE: In the case of an open state at pin e, the module
will have no high voltage output. If you don't use
HV-ON / OFF function at pin e, you can make the
module work by connecting a 10 kΩ (1/4 W or
more) resister between pin e and pin q.
