I just TORTURED my WifCo 55-amp power supply. I have several 600-watt DC to DC boosters. So this morning I hauled the sobbing burping WFCO down to the mechanics shop, and connected the converter and the booster to 4-8-D's that are in a discharged state in an electrical service truck.
The WFCO maxxed out. The booster maxxed out. I checked 10-minutes ago, the gizmos are at 14.5 volts and the converter is still at 55-amps. A strong 120 ac fan is blowing across them both. When it reaches 14.8 volts they both get a cool-down.
Tinker Tinker Cheapskate...
