    B, the output will automatically resume when the fault condition is removed. Setup After setting the internal controls, install the Model 3102D in the NIM bin. Connect the load to the appropriate rear panel SHV connector, set the HV ON/OFF switch to OFF, and set the VOLTAGE control to zero.

  • Page 12: Preventive Maintenance

    Operating Instructions Preventive Maintenance Preventive maintenance is not required for this unit. When needed, the front panel of the unit may be cleaned. Remove power from the unit before cleaning. Use only a soft cloth dampened with warm water and make sure the unit is fully dry before restoring power.

  • Page 13: Circuit Description

    4. Circuit Description A functional schematic of the Model 3102D is included at the rear of the manual. The high voltage module is basically a dc to dc converter which converts low voltage dc power to a high voltage dc output. This output voltage is highly regulated and filtered, and can be varied by the front panel VOLTAGE control.

  • Page 14: Specifications

    A. Specifications Inputs INPUT POWER – The Model 3102D is powered from a standard NIM Bin and power supply, such as the Model 2100, 2000 or 1000. INHIBIT – Logic low or ground inhibits the HV outputs; max logic low ≤0.7 V; logic high ≥1.3 V or open circuit enables.

  • Page 15: Performance

    Performance INHIBIT – LED indicates Inhibit status. OVERLOAD – LED indicates overload status. Performance RIPPLE AND NOISE – ≤3 µV peak to peak at 1 µA. OUTPUT STABILITY – Long term drift of output voltage is ≤0.01%/hr. and ≤0.02%/8 hr. at constant input line voltage, load, and ambient temperature after a 30 minute warmup.
