Save money instead of wasting it
Before power supplies leave the MGV plant, they have to pass an endurance test under a rated load at the maximum permissible ambient temperature. Repeated switching on and off may be used as an additional stress factor. Based on a model calculation, the burn-in test facilities would, under full ohmic load, generate a power loss of 140 kW in the form of heat and as a result, would waste energy worth more than €120,000 each year.
Thanks to the recovery system, some €84,000 of this can be saved, since about 70% of the energy uptake is no longer wasted as heat, but reconverted.
