"Three-phase large current generator" is also known as AC high current generator and large current test device. The three-phase large current generator is suitable for current load test and heating test of frequency 50HZ switches, current transformers and other electrical equipment. It mainly uses It can verify the thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, circuit breaker, protection screen and conduct test and calibration of current relay and switches, time, overcurrent, speed break, transmission and other tests and calibrations check. Pay attention to the following points when purchasing:
1. Input voltage: AC 380/220V 50Hz Three-phase four-wire
2. Power: 12KVA 1*3 3 phases 12KVA group
3. Output current: AC0~2000A stepless adjustable, panel With digital display ammeter
4. Output voltage: an 0-220V bn 0-660V cn 0-1140v
5. Output waveform: The output current is a standard sine wave with small burrs, which is better than the index standard of the power system requirements, and the ripple coefficient is less than 0.3 %. Standard sine wave.
6. Measuring accuracy: (using 0.2S grade material) is actually around 0.3; all currents can be smooth, stable and adjustable, with an accuracy higher than 0.5. The current voltmeter is displayed as a true effective value, with high accuracy and high stability.

7. Output current mode: true effective value is continuously adjustable;
8. Current stability: 0.2%
9. Structural form: Integrated
10. Protection settings: overcurrent, overvoltage
