McPherson, a manufacturer of instruments and optical systems that measure and tune wavelengths of light for spectroscopy, has released a highly regulated, low noise, continuously adjustable high voltage power supply for industrial and scientific research applications. The Model 7640 high voltage power supply series is highly regulated and 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 1kV (2kV and 5kV models are also available) at the front panel by precise 10-turn potentiometer and easy to read 4.5-digit LCD display, which allows users to confidently set and deliver high voltage levels with 0.002 per cent regulation. Instrument rear panel features a scaled analogue input for remote control.
The power supply operates sensitive photomultiplier tubes and related devices for critical photometric and spectroscopy applications. It is proven to provide reliable, stable high voltage.
