HIGH VOLTAGE POWER SUPPLY SOCKET ASSEMBLY WITH TRANSIMPEDANCE AMPLIFIER C6271 The C6271 is a high voltage power supply socket assembly for 28 mm (1-1/8 inch) diameter side-on photomultiplier tubes(PMT), incorporating a regulated high voltage power supply, an active voltage divider, and a transimpedance amplifier. It enables simple yet stable PMT operations by only supplying +15 Vdc and connecting to a potentiometer or a 0 to +5 V for high voltage adjustments. FEATURES Fast High Voltage Programming Response Low Power Consumption Wide High Voltage Output Range Low Cost GENERAL Parameter Applicable PMT Description / Value Unit 28 mm(1-1/8 inch) diameter side-on types – +15 ± 1 Vdc Input Voltage Input Current at Maximum High Voltage Operating Temperature Storage Temperature 60 mA Max. 0 to +50 °C -20 to +60 °C HIGH VOLTAGE POWER SUPPLY SECTION Parameter Output Voltage Range Description / Value 0 to -1250 Unit Vdc Line Regulation Against ± 1 V Input Change ±0.01 % Typ.
