The PHV series are regulated miniature high voltage power modules
using SMD and hybrid technology. They are designed for PCB
mounting. The use of high stability components guarantees a minimal
temperature drift and a very stable output voltage.
Typical applications for these HV power supplies are photomultiplier
tubes, gas chromatography, analytical instruments and wherever where
small size and high output voltage stability is requested.
