The EA3161A is a high-performance 400kW resistive AC load bank professionally designed with a robust trailer-mounted structure, perfectly tailored for mobile power testing scenarios that require frequent long-distance transportation and flexible site switching. Built on a heavy-duty mobile trailer chassis, this load bank eliminates the trouble of repeated disassembly and assembly, enabling convenient and safe long-distance moving and rapid on-site deployment, which greatly improves the efficiency of field commissioning and maintenance work. Featuring dual wide-voltage compatibility, the unit can stably output a full 400kW rated power under both 415V and 480V AC working conditions, fully adapting to diverse industrial power supply standards worldwide. Suitable for both indoor laboratory verification and outdoor field operation, it delivers strong environmental adaptability for generator sets, UPS systems, and power grid engineering testing. In terms of operation, it supports dual control modes, including local touch screen operation for intuitive on-site parameter adjustment and remote PC upper computer control for centralized, unattended batch testing, ensuring flexible, accurate, and efficient power load simulation.
