HIGH VOLTAGE POWER SUPPLY
SOCKET ASSEMBLY

WITH TRANSIMPEDANCE AMPLIFIER

C6271

The C6271 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, an active voltage divider, and a transimpedance amplifier. It
enables simple yet stable PMT operations by only supplying +15 Vdc and connecting to a potentiometer or a 0 to +5 V for
high voltage adjustments.
