ZAC28U-120A Three-phase Zero-crossing Power Regulator


ZAC28U-120A  SSR Three-phase Zero Switch

ZAC28U Series Three-phase Zero Switch


ZAC28U three-phase zero-crossing power regulator is also called three-phase solid state relay module. It is simple to operate, easy to maintain, small and light. The three solid-state relays can be replaced, avoiding the disadvantages of the dangerous concentration of the integrated module. European style safety dustproof structure makes the appearance generous. Red and blue LED lights lets the working status clear at a glance. The blade heat sink is 30% more efficient than a conventional heat sink. The built-in RC capacitor (RC circuit) can improve the inverter’s interference ability in the industrial field and reduce the impact of the open current on the solid state relay. Other functions include: over temperature alarm and output of the radiator, automatic fan start, and can control the industrial resistive load.
