C4900 Datasheet | Hamamatsu

HIGH VOLTAGE POWER SUPPLY UNIT C4900 SERIES The C4900 series are pact PC- board mountable high voltage power supplies, especially designed for photomultiplier tubes. The design offers better performance and improved fail- safe protection. The C4900 and- 01 output negative polarity and the C4900- 50 and - 51 output positive polarity high voltages.
