HAMAMATSU C6270

HIGH VOLTAGE POWER SUPPLY
SOCKET ASSEMBLY
C6270
C6270 is a high voltage power supply socket assembly for 28mm(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 +15Vdc and connecting to a potentiometer or a 0 to +5V for high voltage
adjustments.
