They are designed for PCB mounting (THV series) or chassis mounting (SHV series). The use of high stability components guarantees a minimal temperature drift and a very stable output voltage. Typical applications for these high voltage power supplies are photomultiplier tubes, gas chromatography, analytical instruments and wherever where small size and high output voltage stability is requested. ## Models |Order code|Input voltage range|Output voltage|Output current max.*|Case| |---|---|---|---|---| |THV 12-180P
