Model 632

A Self-Contained Load Bank for Electrical Load Testing of AC Generators

This Generator Test Set provides a fully controllable load that mimics the real load a generator or engine would see in normal operation. Its use allows the performance of both the engine and generator to be evaluated. Now you can be sure that your generators and alternators are providing the output they should—at the proper voltage and frequency.

Fast and easy-to-use, this test set is fully self-contained with no external equipment except adapters required.
