Phenix Group Co.,Ltd.

Full-shielded three phase voltage regulating module STY combine three phase phase-detection,phase-shift circuit,trigger circuit and three groups antiparallel unidirectional Silicon Controlled Rectifier(SCR),which is supported by our three phase synchronous transformer module(model TB-3)( synchronous transformer also supply working power to STY),can automatic control or manual control with potentiometer,don't need external any circuit and working power supply,to change silicon controlled rectifier(SCR) conduction angle.
 

In principle,three phase voltage regulating module STY is applicable for 380V,50Hz three phase network, divided into four types according to control signal E,F,G and H, types list is as belows:

	CONO-5V: E	CONO-10V: F	CON4-20mA: G	CON1-5V: H
35A	STY-380D35E	STY-380D35F	STY-380D35G	STY-380D35H
75A	STY-380D75E	STY-380D75F	STY-380D75G	STY-380D75H
