VPX Load Board 3U

  • The VPX Load Board serves to simulate loads on VPX systems

  • Both electrical and thermal conditions can be simulated

  • The load board switches itself off at a temperature on the topside of the load test card or in a rack at 120 degrees Celcius  +/- 5K.  Once cooled, it turns itself back on

  • 5V must always be connected as control voltage

  • Voltages are tapped at the VPX bus via the P0 and P1 plug

  • The incoming voltage levels for the voltages 5V, 12V, 3.3V, +12V-AUX, -12V-AUX, and +3.3V-AUX can be measured close to the plugs P0 and P1.  These measuring points are run via the plug X1 (on the front plate) 

  • 4 PTC resistors (PT100) are attached to the load test card:  On the front at bottom and top.  It is also possible to measure the temperature on the load test card or in a rack via these.  These PTS resistor connections are also run via the plug X1

The following load streams can be switched with the coding and tilt lever switches located on the front plate:
