HIGH VOLTAGE POWER SUPPLY
SOCKET ASSEMBLY (DP TYPE)
C12842 SERIES
The C12842 series is a high voltage power supply socket assembly
for head-on photomultiplier tubes (PMT). It uses a Cockcroft-Walton
type high voltage power supply that ensures high output linearity of
photomultiplier tube while maintaining low power consumption.
FEATURES
●Low Power Consumption
●Superior DC Output Linearity
●Low Ripple/Noise
●Shutter Function (-01S, -02S)
