This 400kVA RL load bank is designed for aircraft engine testing, operating at 208V/400Hz with combined resistive and reactive loads. Its power factor is adjustable from 0.3 to 1. Resistive load steps at 1kW minimum and inductive load at 1kVar. Three phases support independent regulation, and test voltage can be customized to 208V, 400V, 415V or 480V. It enables remote control via Modbus TCP/RTU and real-time monitoring of voltage, current, power, power factor and frequency. Multiple safety protections include overcurrent, overvoltage, air pressure, fan overload and overtemperature alarms, etc.
