HIGH VOLTAGE
POWER SUPPLY UNIT
C4900
SERIES
The C4900 series are compact PC鈥揵oard mountable high voltage power supplies, especially designed for
photomultiplier tubes. The design offers better performance and improved fail鈥搒afe protection.
The C4900 and鈥?1 output negative polarity and the C4900鈥?0 and 鈥?1 output positive polarity high voltages.
