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.

The 10A voltage and current meter itself has a built-in shunt, and the 50A / 100A voltage and current meter needs to be purchased separately (the above options can be checked for purchase).

The power supply voltage of the meter must be 4--30V. If it exceeds 30V, DU stand-alone power supply is required. Please connect according to the figure. The four points of the shunt cannot be changed .

Digital display meter and shunt are used together, 10A can not be used with 50A. 100A shunt.
