This controller uses 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.
The output voltage is adjusted anywhere between 10V ~ 220V for use with electrical appliances.
Application examples: electric furnace, water heater, lamps, small motor, electric iron, electric stove, lighting dimmer, small motor speed, electric iron thermostat, and achieve dimming, thermostats, pressure regulator effect, etc.
SCR model: BTA41600B
Input voltage: AC 110 or 220V
Voltage regulation: AC 10~Input Voltage
Maximum power: 4000 W
Current: 25A
Under 10amps current, does not need extra cooling.
Over 10amps current, needs cooling fan.
Voltage Regulating Mode: Potentiometer (270 degree)
Efficiency: 90%
Size: 85 x 55 x 38mm, knob inner hole 6mm
Note that the load must be connected before the voltage is adjusted.
SCR is mainly used for resistive loads (electric heating incandescent lamps, etc.), most of the single-phase AC motors are also available, but they are not guaranteed. If the current is too large, the module may burn out besides burning the fuse.
