DC400V-20KW-R DC load box built purely resistive load; power input with sub-type combination of control, it can simulate any combination of various power loads. Battery, charging pile, rectifier modules and other equipment DC power supply and full load testing needs, the production workshop, laboratory, installation and commissioning, research and development necessary testing tools.
Performance parameters according to testing requirements, any combination, set discharge power.
Host has a temperature overheat alarm protection: overheating due to special reasons, it can automatically cut off the load.
New power components, high power density, no red heat phenomenon, the whole by the resistive load components.
Power input with sub-type switch control. Work load using energy method, using forced air cooling mode.
Axial fan with a small fan with air flow, good heat dissipation, low noise characteristics.
The above features make the machine in safety, reliability, noise reduction is superior to imported products.

Third, the resistive load module
Resistive load module consists of a number of special nickel-chromium alloy resistance connection is made. Alloy resistive element as a power by special alloy processing, external material made of 304 stainless steel fins, the intermediate filling made of an insulating medium, in which the resistance of the package to meet the needs of the load test.
Alloy resistance insulation properties, high thermal performance, even heat conduction, the operating temperature of only 1/3 of the design temperature, low temperature drift, resistance stable, long working hours without red hot. And with acid, salt spray, rain, moisture, corrosion effects, all-weather use.
Resistive load module uses proprietary technology, the alloy resistive insulating material fixed plate, the entire module sealing process, through internal insulation and insulation plate two isolated, even in wet weather but also to ensure insulation and security, and the prevention phase o resistance due to resistance caused by the decline in short-circuit accident.
