Portable relay protection tester, microampere power relay protection tester manufacturer
1. With 4-phase voltage and 3-phase current output, it can easily perform various combination outputs for various types of protection tests. Each phase voltage can output 120V, and the current of three can output 120A. The fourth phase voltage Ux is a multifunctional voltage item, which can be set to four types of 3U0 or detect synchronous voltage, or output under any voltage value
