Built for demanding mobile power testing applications, the Simplex Atlas-Megawatt Trailer Load Bank delivers up to 1000 kW of capacity wherever you need it. Whether you’re commissioning a generator on a remote job site or running routine load tests at a data center, this unit is engineered to perform.

Flexible Power, Any Voltage Rated for dual 240/480V AC 3-phase operation and compatible with virtually any voltage up to 480V AC (1Ph or 3Ph), this load bank adapts to your power source — not the other way around. It supports 50, 60, and 400 Hz frequencies, making it equally at home on domestic or international projects.

Precise Digital Control A digital load step controller with 5 kW resolution lets operators enter any target load value directly — the controller does the rest, applying load automatically within nominal 5 kW resolution. No guesswork, no manual adjustments.

High-Capacity Cooling A 10 HP fan delivering 27,700 CFM keeps the unit running in ambient air temperatures up to 120°F, with an air temperature rise rated up to 480°F.

Road-Ready Trailer Mounted on a DOT-compliant dual-axle trailer (ST205-75-R14 tires, 5000 lb. gross weight capacity), the unit ships with electric and mechanical parking brakes, 4-leaf spring suspension, ICC lighting, and your choice of ball hitch or pintle ring connection. Total combined weight with trailer is 4,000 lbs.
