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.
FEATURES
Superior DC Output Linearity Fast High Voltage Programming Response Low Power Consumption Wide High Voltage Output Range Low Ripple/Noise Low Cost
