This controller uses novel bi-directional high-power SCR. 

Connect it with lamp or home appliance in a series connection, then rotate the knob for dimming, speed, voltage, temperature control.

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, lighting dimmer, small motor speed, electric iron thermostat, and achieve dimming, thermostats, pressure regulator effect.

Adopts double insulation; there will be no electric leakage if short-circuit or SCR burn out.

Can prevent peak voltage and electrical surge; RC absorption and fuse enhance usage safety.

Aluminum case prevents it from easy damage; filled tin prevents it from heating when in huge current.

With protective cap and connection post; thicker and larger heat sink.

Wide application: electric furnace, water heater, lamps, small motor, electric iron etc.
