High-Voltage Power Supply
Jun 2011
McPhersonRequest Info
CHELMSFORD, Mass., June 21, 2011 — McPherson Inc. has announced a highly regulated, low-noise, continuously adjustable high-voltage power supply for industrial and scientific research applications.

The Model 7640 series is designed for use with photomultiplier tube, channel-electron-multiplier and microchannel-type detectors, and other devices requiring a stable source of high voltage.

Voltage is set at any point between zero and 1 kV (2- and 5-kV models also are available) at the front panel by a precise 10-turn potentiometer and easy-to-read 4.5-digit LCD that allows users to set and deliver high-voltage levels with 0.002% regulation. An instrument rear panel features a scaled analog input for remote control.

The power supply was engineered to produce regulated, low noise, high voltage for sensitive high-gain detectors in spectroscopy systems.

It operates photomultiplier tubes and related devices for critical photometric and spectroscopy applications, providing reliable and stable high voltage.
