VME load card

WIENER VME load boards are designed to test VME crate power supplies and fan trays by drawing power from the VME backplane and dissipating it as heat. A series of switches on the module front panel allows for easy adjustment of the current draw for each voltage channel.

By monitoring exhaust air temperature above a VME load board it is possible to locate VME slots with cooling issues. VME load boards also provide an easy way to test the maximum current of a crate power supply and to confirm current trip points behave as expected.


  • VME64x card, 6U, single wide format
  • Front Panel switches to control current load
  • Up to 10A load per board for 5V and 3.3V
  • Up to 3A load per board for +12 and -12V
  • Different versions for each VME specification to test every voltage
  • High power versions available for testing high power 5V systems
  • LED indicator lights to show current draw
