37 Pin Sub-D Connector
The Power Supply will have the FEMALE SUB-D connector on the back panel.
The MALE SUB-D connector with solder cups is provided with the unit.

    1.  
      1. Voltage Reference: 0-10 Volts Input = 0 to Full Output Voltage. This Reference must be connected to 10 Volts when using this supply in Current only mode, otherwise the auto-crossover control will believe you are requesting near zero voltage and no out will result. This only operates in remote mode.
      2. Current Reference: 0-10 Volts Input =0 to Full Output Current. This Reference must be connected to 10 Volts when using this supply in Voltage only mode, otherwise the auto-crossover control will believe you are requesting near zero current and no out will result. This only operates in remote mode.
      3. Remote off/ Reset Command: This pin must be pulled LOW in order to turn HV Off and Reset any Fault that has terminated normal operation. This pin operates as a momentary LOW and must be returned HIGH for next cycle normal operation. DO NOT rely on this for Personal Safety, always shut off circuit breaker and remove power plug when working on your load or system in which this power supply is connected. This pin will operate in local and remote mode, as well as the front panel HV off/ reset.
      4. Remote X-Ray On Command: Pull this pin Momentary LOW to apply HV On. This Pin must be returned HIGH before pulling LOW to activate HV On. If held LOW the power supply will not be able to apply the HV On condition. This pin will not activate HV On with an existing Fault condition on the display. This pin does NOT operate in local mode.
      5. No Connection:
      6. Remote kV Monitor: 0-10 Volts = 0 to Full Output Voltage. Output Impedance of this device is 1k Ohms. This Function is available in any mode.
      7. Remote Over Voltage Reference:  0 to 5.0 Volts = 0 to Full Output Voltage over rides the internal Over Voltage setting which is fixed at 105% of the full output voltage.  This function is available in any mode.
      8. Remote Over Current Reference:  0 to 5.0 Volts = 0 to Full Output Current over rides the internal Over Current setting which is fixed at 105% of the full output current.  This function is available at all times.
      9. +5 volts.
      10. Filament Monitor.  5 volts = 5 Amps.  This signal is present in all modes.
      11. +15 Volts   20mA Max
      12. -15 Volts    20mA Max
      13. Common.
      14. HV On Signal Indicator. When HV On is commanded this pin goes Low. Its output impedance is 2k ohm, and the High position is +5 Volts. This signal is always present in Local and Remote control.
      15. Common.
      16. Local/ Remote Command: Pulling this pin LOW and holding will remove control from the front panel. The Front Panel Potentiometer References will be over ridden as well as the HV On Command. Meters will function normally and the Preset button will read the remote program reference inputs instead of the Front Panel Potentiometers. All LED function remains.
      17. Temperature:  This pin reads the temperature of the IGBT in the power driver. The measurement is in Kelvin/100. Room temperature will read 2.93V or 293o Kelvin. This function is available in any mode.
      18. Power Monitor. 0 to 10 volts is 0 to full power output +/- 5%. This signal is present in all modes if so equipped.
      19. Remote Current Monitor:  0-10 Volts = 0 to Full Output Current. Output Impedance of this device is 1k Ohms. This function is available in any mode.
      20. Fault Signal Indicator.  When Fault is triggered this pin goes Low. Its output impedance is 2k ohm, and the High position is +5 Volts. This signal is always present in Local and Remote control.
      21. Common.
      22. +5 volts.   100mA Max.
      23. Remote Filament Reference Input.  0 to 5 volts = 0 to 5 amps. A 1k ohm pot or op amp with lower than 250 ohms output impedance must be used. This signal overrides an internal op-amp with output impedance of 50k ohms.
      24. Reference Voltage +10 Volts:  5mA Max Current Draw.
      25. External Interlock:  This pin must be held LOW in order to operate power supply. A HIGH or an OPEN on this pin will trip the unit off via an Interlock FAULT and block the application of HV ON. This pin must be held LOW before the OFF/ RESET command can be used to clear the fault. This function is always available.
      26. Remote X-Ray lamp On.   {+} Provides +24 volts source for a relay to energize a lamp when high voltage is enabled 75mA Max.
      27. Remote X-Ray lamp Return.  {-}Return for +24 volts lamp.
      28. Pump Voltage Return.  {-}Return for +24 volts for coolant pump relay.
      29. Pump Voltage +24 volts:  {+} Provides +24 volts source for X-Ray tube coolant pump relay. Other voltages are available 75mA Max.
      30. Filament On Remote:  Pull this pin Momentary Low to turn ON Filament. High is +5 Volts.
      31. Filament Off Remote:  Pull this pin Momentary Low to turn OFF Filament. High is +5 Volts
      32. Filament On Signal Indicator:  This pin is normally high (+5 Volts) with Filament OFF and Goes Low when Filament is ON.
      33. Common:
      34. Common:
      35. Common:
      36. Spare:   
      37. Spare:
