Features 1、Built-in electromagnetic interference filter keeps electromagnetic interference suppression. 2、With maximum 20W power consumption, voltage control board also supports simple installation. 3、Low frequency protection means that 60 Hz system inflection point value is 55 Hz, 50 Hz system inflection point value is 45 Hz. And inflection point value is the factory default value. 4、Automatic over-excitation shutdown is that excitation voltage exceeds 52 ± 2 VDC automatically shuts off after a delay time. 5、Via strict quality control standards, voltage regulator quality is guaranteed, you can use it with confidence.
