1kW minimum step allows precise simulation from no-load to 200kW full load, supporting diverse testing requirements from small battery chargers to large generator sets.
Fast load step changes (contactors electrically operated and held) enable dynamic simulation of real-world load conditions, including sudden load rejection tests and transient response analysis.
Utilizes world-famous brand components: Schneider/ABB contactors, industrial-grade PLC, and self-developed nickel-chromium alloy resistive elements (stainless steel sheathed, 3-year warranty).
Resistive elements mounted in easily accessible, slide-out trays. Modular design simplifies maintenance, reduces downtime, and lowers total cost of ownership.
Standard: Push-button panel with digital meters;
Optional: 7-inch color touchscreen HMI with programmable logic controller (PLC) that allows customized automatic test sequences. Users can pre-set load profiles (multiple steps with duration) for fully automated generator validation.
Over-temperature monitoring with automatic load shedding, fan failure detection with load interlock, branch circuit fuses on each load step (50kW max per branch), emergency stop button, and separate control/thermal compartments to prevent heat damage to sensitive electronics.
200kw Resistive Load Bank is ideal for commissioning, proof-of-load testing, periodic reliability exercises, and preventing engine "wet-stacking" (unburned fuel build-up) with minimum load regulation. Meets NFPA 110 standards for emergency standby power systems.
Validates performance, runtime (battery discharge test), and efficiency of 3-phase UPS units in data centers, hospitals, and critical infrastructure facilities.
Tests grid-tied and off-grid inverters under controlled resistive loads to verify power output, thermal performance, and grid compliance.
Evaluates battery and inverter performance in ESS applications, including charge/discharge cycle testing and system validation.
Ensures reliability of AC power sources and Power Distribution Units (PDUs) in manufacturing environments, automotive plants, and aerospace facilities.
