30A Drop Tester

Developed to test DC machines, measuring the volt drop accurately from the commutator through the winding and back to the commutator. Historically such testing required heavy-duty equipment with a weight that was difficult for one engineer to handle. The 30A drop tester has been specifically designed to offer portable testing, operating from a 85-264V, 50-60Hz supply, with multiple current settings.
