Could something like this be hardwired, too my 900w-1500w space heater, to reduce voltage to say 450w-750w?

[Debraj1978]

Yes. Since the control is based on triac phase control, it can be used to reduce the voltage going to your space heater. That would be a resistive load.

Hi,

This is simple Triac based phase control. Uses BT136. Works great for AC motors. and the entire BOM cost is $1.

@Debraj1978 hi ,i wonder where can i can buy such a device?

@surrounded24

I do not sell any product. I made it as my hobby :-)

I presume this one uses PWM right?
