HIGH VOLTAGE POWER SUPPLY SOCKET ASSEMBLY C12597-01 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 extended DC output linearity by only supplying +15 V and connecting to a potentiometer or a 0 to +5 V for high voltage adjustments.
