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..
