DESCRIPTION
The Series PSM10 is a range of versatile high voltage component power
supply modules equally suited to both laboratory and development
work and for specification in OEM equipment. Powered from 24V DC,
these units allow full range control and monitoring of voltage and
current via 0-10V analogue signals and inhibit signal input. Positive or
negative polarity models are available.
As well as photomultipliers, the PSM10 is suitable for gamma cameras,
image scanners, spectroscopy, scintillation counters, microchannel
plates, piezo crystal devices, ultrasonic transducers, electron beam
deflection, electrorheological fluids, and electrostatic lenses (SEMs
and STMs).
Output Polarity:
Positive or negative to order.
Line Regulation:
Less than 0.005% change in output voltage over range 22V to 26V at
rated output power.
Voltage Load Regulation:
Less than 0.005% change in output voltage for change in output current
from zero to max output current at rated output voltage.
