Manufacturer: Avtron Power Solutions (Model 5900)
The Avtron 5900 is a high-capacity 3000 kW outdoor resistive load bank engineered for mission-critical testing of large generators, paralleling switchgear, UPS systems, turbine packages, microgrids, and industrial electrical infrastructure. Designed for continuous, outdoor-rated operation, the 5900 delivers unity-power-factor loading from 5 kW up to 3000 kW with no cool-down period required.
Built with heavy-gauge aluminized steel, high-velocity blower systems, redundant airflow protection, and integrated safety controls, the 5900 Load Bank is ideal for utility providers, power-generation OEMs, industrial plants, data centers, and rental power fleets requiring reliable full-load testing.

480 VAC, 3-phase, 60 Hz (rated), with operation possible at lower voltages
5 kW load step resolution for precise load control
Outdoor-rated, continuous-duty construction
Two 20 HP blower motors providing 32,000 CFM cooling airflow
Multiple safety interlocks: airflow switches, overtemperature sensors, motor overload protection
Heavy-duty aluminized steel enclosure with hinged weatherproof louvers
Forklift-ready base with pad-mounting bolt holes
Local operator interface with status indicators and STOP/RESET safety control
