Vector Electronics and Technology, Inc. VME and VME64x load boards provides a means to test the power generated and cooling capability of VME systems.

The 6U VME and VME64x load board functions to test a system’s cooling capability by applying a variable load to the power supply for verification, then generating necessary heat to confirm the chassis’ cooling. This enables locating hot spots in the chassis so the airflow can be properly directed.​
