Manufacturer: Avtron Power Solutions
The 500 kW Trailer-Mounted Load Bank is a robust, outdoor-rated resistive load bank engineered for full-capacity testing of generators, UPS systems, microgrids, and industrial electrical infrastructure. Built from Avtron’s proven 5000 SERIES load-bank architecture, this unit delivers accurate, unity-power-factor loading with continuous-duty operation—no cool-down period required.
Its rugged aluminized-steel enclosure, branch-circuit fuse protection, high-velocity cooling, and optional SIGMA digital control packages make the 500 kW Load Bank ideal for service teams, rental fleets, data centers, utilities, and large-scale commissioning projects.
