Three phase AC400kW load bank with pure resistive AC load
IUXPOWER multi loop AC aging load box with pure resistive load; it can simulate all kinds of power load, meet the power unit, UPS power supply, inverter AC power full load detection is needed, production, installation and commissioning, testing laboratories, scientific research and development necessary out.
The main engine has temperature overheating automatic alarm protection function: due to special reasons, when overheating occurs, it can automatically cut off the load.
The whole machine is composed of resistive load. The load adopts energy dissipation method, and the heat dissipation adopts forced air cooling mode.
The fan adopts small axial flow fan, which has the characteristics of large air flow, good heat dissipation and low noise.
The above features make the whole machine better than imported products in safety, reliability and noise reduction.

Three , resistive load module
The resistive load module is connected by a number of specially made nickel chromium alloy resistors. Alloy resistance as power element, by special alloy manufacture, the external heat sink made of 304 stainless steel material, the middle filled by an insulating medium, the resistance package in which can meet the needs of the load test.
Alloy resistance good insulation properties, high radiating performance, uniform heat conduction, the operating temperature is only 1/3 design temperature, small temperature drift, stable resistance, long time no red hot work. And with acid, salt, fog, rain, moisture-proof, anti-corrosion effect, all-weather use.
Resistive load module using the exclusive technology, the alloy resistance is fixed on the insulating material plate, the module is closed after processing, internal insulation and insulation board two isolation, security and insulation guarantee even in wet weather can also, and can prevent the adjacent resistance due to short-circuit accident caused by resistance decreased.
