Three-phase AC load switching cabinet switching power supply test resistive dummy load switching power supply with the capacity to detect the three-phase AC load box Product Category: AC R load box Product Number: AC380V-30KW Product details I. Product Overview 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. Three-phase AC load switching cabinet switching power supply test resistive dummy load switching power supply with the capacity to detect Second, the technical parameters of equipment 2.1 Technical Specifications 1. Rated input voltage three-phase four-wire 380V (three-phase four-wire) 2. Rated input Three-phase power 30KW, 10KW 3. single-phase single-phase power sub-file sub-file: 100W / 200W / 200W / 500W / 1KW / 2KW / 2KW / 4KW 4. Power Factor PF = 1 5. Load Accuracy ± 5% 6. significant three-phase voltage-type way, real-time display ammeter head 7. Power supply single phase AC220V / 50HZ 8. control panel manual control, segmented manually adjustable. (Main circuit contactor controlled, adjustable air switch segment). 9. Class F insulation AC three-phase switching cabinet switching power supply test load resistive dummy load switching power supply with the capacity to detect 10 protection class IP20 (for indoor use) 11. Fan Noise 65 db 12. Cooling Forced air cooling : next into the wind, the wind 13. 14. The work can work over temperature alarm protection, overtemperature protection, Beeper, overcurrent protection 15. The external dimensions of the host: width 500 * depth 700 * height 1260mm 16 . Ambient temperature -10 ℃ ~ + 50 ℃ 17. moves using truck-type casters, before and after 2 18. applicable Relative humidity ≤95% 19. 2.2 meters altitude ≤2500 Protection (1) over-voltage protection : Load the 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 force uninstall manually. (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.
