100KW Constant Power DC Load Bank 850V for Fuel Cell Stack Testing EA3211A

This 100kW DC load bank is specially developed for testing hydrogen fuel cell stacks and complete fuel cell systems, supporting a maximum test voltage of 850VDC. It accurately simulates variable actual operating loads to conduct full-power discharge, dynamic load switching and aging tests. The equipment precisely captures output efficiency, thermal performance and protective functions of fuel cell products, delivering stable and reliable load simulation for R&D verification and factory inspection of hydrogen energy equipment. Working Cycle: Continuous operation. Load Accuracy: ±3% Remote Control: An external Ethernet port is provided to mimic the control screen using free software for remote control using a customer-provided laptop, PC, or tablet. Or Modbus RTU/RS485 is available. Instrumentation: Digital metering (V, A, kW) and data logging. Control Power: Via external 380-415V AC, 3P5W, 50Hz. Cooling System: Integral forced-air cooling system, bottom inlet, up outlet. Noise: ≤82dB（3M） Load Elements: High-capacity Nichrome load elements. Elements are fully supported with stainless steel rods and high-temperature refractory ceramics for quick heat discharge. Safety Features: Over-temperature, over/under voltage, cooling-air loss, and current imbalance protection. Load Connections: Copper Busbars or as per request. Daisy Chained: Multiple load banks can be hooked together for higher load capacity. Enclosure: Heavy-gauge steel outdoor enclosure with powder-coat finish. Hinged access doors with lockable latches. Forklift pockets for easy mobility.
