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 Compact and Lightweight High stability Low Power Consumption Fast Response Wide Variable Output Range Ample Protective and Fail–safe Functions SPECIFICATIONS C4900 C4900-01 Unit +12 ± 0.5 C4900-50 +15 ± 1 C4900-51 +15 ± 1 +12 ± 0.5 V with no load 14 15 14 15 with full load 90 95 90 95 Parameter Input Voltage Range Input Current a Variable Output Range Specification Guaranteed Output Voltage Range Output Current b 0.6 mA (Typ.) 0 to –1250 0 to +1250 V –200 to –1250 +200 to +1250 V 0.5 ±1 V or 0.5 V Change b 0.6 0.5 mA (Max.) ± 0.01 % (Typ.)
