Dual-Voltage 400V/690V AC 300kW Resistive Load Bank for Power System Testing1. This high-performance 300kW AC resistive load bank is engineered for comprehensive testing of generators, UPS systems, and industrial power equipment. It features dual voltage compatibility (400V / 690V) with fully adjustable resistive load steps, enabling accurate simulation of various operating conditions.2. Equipped with real-time monitoring of voltage, current, power, and temperature, along with multi-layer safety protections (over-voltage, over-current, over-temperature, short circuit), it ensures reliable and safe operation during performance verification, acceptance testing, and long-term stability tests of power systems.
