The TSL Model 1057 Load Bank is a portable, self-contained test unit designed for testing and/or loading electrical generating equipment.
The TSL Load Bank is capable of providing a selectable resistive load of any value up to 33 KW to a single or three-phase generator, at any frequency from 50 to 1000 Hz. Through selectable input connections, the load bank may be used on generators of 120 or 240 VAC single phase, 120/208 VAC and 240/416 VAC three-phase 4-wire, or 240 VAC 3-wire.
The TSL Load Bank is skid mounted and is designed for storage and operation outdoors, under adverse weather conditions. It is portable and designed to be moved by a two man crew.
TSL has delivered over 500 Load Banks to the U.S. Armed Forces. We also design and manufacture custom Load Banks. Contact us for more information.
