The Mirion Model 3102D High Voltage Power Supply is a single-width NIM module designed primarily for use with photomultiplier and electron multiplier tubes. But it can be used with any detector requiring a bias voltage up to 2000 V and a current level of 1 mA or less.
The 3102D unit allows the user to select from two continuously adjustable outputs, one ranging from ±15 to ±2000 V dc and the other from ±1.5 to ±200 V dc. The output voltage is measured and displayed by a three-digit voltmeter. In addition, this unit allows the user to select the output voltage polarity with an internal control.
The 3102D NIM can withstand any overload or short circuit for an indefinite period of time. It can be set using an internal jumper to allow for a manual reset or an automatic reset when the fault condition is removed.
The 3102D NIM features an output rise time of five seconds to protect preamplifiers and detectors from excessive surge currents while charging.
