HIGH VOLTAGE POWER SUPPLY SOCKET ASSEMBLY C6270 C6270 is a high voltage power supply socket assembly for 28mm(1-1/8 inch) diameter side-on photomultiplier tubes (PMT), incorporating a regulated high voltage power supply and an active voltage divider. It enables simple yet stable PMT operations with extended DC output linearity by only supplying +15Vdc and connecting to a potentiometer or a 0 to +5V for high voltage adjustments. FEATURES Superior DC Output Linearity Fast High Voltage Programming Response Low Power Consumption Wide High Voltage Output Range Low Ripple/Noise Low Cost SPECIFICATIONS Description / Value 28mm(1-1/8 inch) diameter side-on types +15 ± 1 45 0 to -1250 100 50 ±0.01 0.008 0 to +5V or external 50kΩ potentiometer 80 ±0.01 0 to +50 -20 to +60 Parameter Applicable PMT Input Voltage Input Current at Maximum High Voltage Output Voltage Range at – 1000V a Linear DC Output of PMT at – 500V Line Regulation Against 1V Input Change Ripple/Noise in High Voltage Output High Voltage Control High Voltage Programming Response b Temperature Coefficient of High Voltage Output Operating Temperature Storage Temperature Unit — Vdc mA Typ.
