ACTIVE D TYPE
SOCKET ASSEMBLY
E12788
The E12788 is a D-type socket assembly designed for 28
mm diameter side-on photomultiplier tubes. It uses transistor
circuit for the voltage divider circuit, making it ideal for use in
high output applications.
FEATURES
GActive Voltage Divider Circuit
GLow Power Consumption, Low Heat Generation
Without incident light, power consumption is 1/15 of resistive
divider type.
GExcellent Output Linearity
GHigh Output Current even at Low Supply Voltage
