NX-5000IIIThree-phase alternating current generator
The NX-5000III three-phase alternating current generator (abbreviated as three-phase current booster) is a testing equipment independently developed by our company.
The NX-5000III Three-Phase AC Current Generator (abbreviated as Three-Phase Current Generator) is a testing equipment independently developed by our company. Integrating the advantages of domestic and international counterparts, it employs numerical control technology with strong interference resistance. Compared to previous generations, this model features low-power consumption, high capacity through the use of self-tapping autotransformer voltage regulators and high-permeability iron cores in its converter design, resulting in superior output power, compact size, and lightweight construction. Primarily used for thermal relay testing, motor protector calibration, contactor evaluation, circuit breaker inspection, air switch analysis, switchgear system assessment, and protective panel verification.
