High Voltage Power Supply and Divider Assembly
for Standard 28 mm (1-1/8 inch) Side-on Photomultiplier Tube
The C8991 is a compact and lightweight socket assembly
incorporating a socket, voltage divider circuit and high vol-
tage power supply designed for use with 28 mm(1-1/8") side-
on type photomultiplier tube. It features low power consump-
tion and superior output linearity comparing with conventional
socket assemblies. In addition, it allows easy handling to
operate with +15 V input voltage and connecting to a poten-
tiometer or a +0.2 V to +1.2 V for output voltage adjustments.

VOLTAGE PROGRAMMING
RESISTANCE PROGRAMMING
The blue lead should be insulated as it is not used.
Input a control voltage. The voltage to the photo-
multiplier tube sets to approximately 0 V when the
control voltage is 0 V.
Turning the potentiometer wiper
clockwise(CW) increases the
high voltage output.
