HIGH VOLTAGE POWER SUPPLY
SOCKET ASSEMBLY (DP-TYPE)
C9028-01
The C9028-01 is a high voltage power supply socket assembly for 28 mm (1-1/8") diameter head-on photomultiplier tubes (PMT), in-
corporating a regulated high voltage power supply and an active voltage divider.
It enables simple yet stable PMT operations with extended DC output linearity by only supplying +15 V and connecting to a potenti-
ometer or a 0 V to +5 V for high voltage adjustments.
