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.
