VGM
ZONZEN
Product Description
VGM series Solid State Relays are Dual AC relays,Triac or SCR Output. The Triac version of the zero switching relay is an inexpensive solution for resistive loads. The zero switching relay switches on when the AC sine voltage just crosses zero,and switches off when the current crosses zero. The SCR Output is Dual SCR Power Hybrid technology provides highly efficient thermal management for greatly increased cyclic life.
Benefits
Weak power part and strong power part are isolated by transformer.
Wide adjustment range, no mechanical wear and tear, long service life.
Solid package, small size, easy installation, shockproof, anti-corrosion, stable and reliable work.
Applications
Mainly used in DC power supply lighting, electric car, electromagnet and other equipment for dimming, speed control and power control.
