HVSys provides individual channel control and monitoring of the high voltage power supply of each channel, using only 3 wires.
A unique feature is that HV is generated on the base of the photomultiplier, avoiding the inconvenience and problems associated with high voltage distribution.
All that is required is a +12V supply with sufficient current capability for the number of channels chosen; the supply current required is
less than 25 mA per channel.
The system is controlled by a PC with a PCI card and RS485 interface, operating under Windows® 98/NT/XP. The PC performs independent setting and monitoring protocols for voltage, current, and temperature. HV is supplied by individual power bases, of the PSM
series, mounted directly on the base of each
photomultiplier. HVSys 多通道高壓電源控制系統 特點:
