1000 kW Trailer-Mounted Load Bank

Manufacturer: Avtron Power Solutions (Series 5605 with 4600-Series Load Bank)

Overview

The 1000 kW Trailer-Mounted Load Bank is a heavy-duty, outdoor-rated resistive load bank built for large-scale generator, UPS, microgrid, and electrical system testing. Designed around Avtron’s proven 4600-Series load bank and mounted on a highway-rated 5605 dual-axle trailer, this unit delivers 1000 kW of unity-power-factor loading with continuous duty, no cool-down period, and superior reliability in demanding field environments.

Engineered with a welded steel trailer frame, aluminized-steel load bank construction, branch-circuit fuse protection, and high-velocity cooling airflow, this system is ideal for rental fleets, utility contractors, commissioning teams, and mission-critical facilities requiring dependable high-capacity load testing.
