SPECIFICATIONS

FEATURES

C12597-01 is a high voltage power supply socket assembly for

28 mm (1-1/8 inch) diameter side-on photomultiplier tubes (PMT),

incorporating a regulated high voltage power supply and an active

voltage divider. It enables simple yet stable PMT operations with ex-

tended DC output linearity by only supplying +15 V and connecting

to a potentiometer or a 0 to +5 V for high voltage adjustments.
