HIGH VOLTAGE POWER SUPPLY UNIT
C4900 SERIES
The C4900 series are compact 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. PATENT
FEATURES
