Three-phase AC AC380V-50KW AC resistive load bank test dummy load AC test load cabinet three-phase AC load box Product Category: AC R load box Product Number: AC380V-50KW Product Description: meet two kinds of voltage use. Single-phase 17KW, three groups can be loaded in parallel using 51KW; three-phase four-wire system using a 51KW. Product details I. Product Overview AC380V-50KW three-phase AC load box built purely resistive load; can simulate a variety of power load to meet generators, UPS, inverter and other AC full load testing needs, the production workshop, laboratory, installation, research and development necessary testing tools. Host has a temperature overheat alarm protection: overheating due to special reasons, it can automatically cut off the load. Whole by the resistive load components. Load using energy method, using forced air cooling mode. Axial fan with a small fan, with air flow, heat dissipation, low noise characteristics. The above features make the machine in safety, reliability, noise reduction is superior to imported products.

Protection class IP20 (for indoor use) 12. Fan Noise 65 db 13. Cooling Forced air cooling: Side into the wind, the wind side 14. The work of continuous work 15. overtemperature protection overtemperature alarm beep overcurrent protection 16. The external dimensions of the host: width 500 * depth 700 * height 1260mm 17. Ambient temperature - 10 ℃ ~ + 50 ℃ 18. moves using truck-type casters, before and after 2 19. applicable Relative humidity ≤95% 20. 21 meters altitude ≤2500 protection functions: (1) over-voltage protection: load input voltage exceeds the safety threshold, automatic unloading and alarm. (2) over-current protection: When the load input current exceeds the safety threshold of the total load is automatically unloaded. (3) Temperature protection: load temperature exceeds the safety threshold, automatic unloading and alarm. (4) Emergency stop: a key to manually force uninstall, stop locked state can not be loaded. (5) Fan fault protection: when any fan fails, the load stop working to avoid fires and other accidents caused by burning or cooling load can not be normal. (6) Security Monitoring: When the indicator by software, visual monitor the load state, abnormal shutdown protection, suggesting causes of downtime. Choose over protection are configurable, you need to be customized according to the actual work. Three-phase AC AC380V-50KW AC resistive load bank test dummy load AC test load cabinet
