Specifications:
This controller uses novel bi-directional high-power SCR. It can be very convenient adjust the current up to 25A, and solve the over current problem of the heating wire resistance is too small in the case of cooling causing good.
The output voltage is adjusted anywhere between 50V-220V for use with electrical appliances. It can use to such as electric stove, water heater tune thermal, lighting dimmer, small motor speed, electric iron thermostat, and achieve dimming, thermostats, pressure regulator effect.
100% brand new and high quality.
Input supply voltage: 110V ~ 250V AC
The output voltage:50V-250V
The maximum output power: 2000W
The maximum output current :25A The voltage regulating range:50V-250V AC

Before you attempting to wire the controller, make sure all power is disconnected.
1. Cut any one of the battle line or zero line of the lamp or electrical appliances, and connect wires refer to the “wiring diagram” (NO.7 picture)
2. Turn on the power, and adjust the potentiometer.
