AC110V to 220V Voltage Regulator,4000W SCR Electric Dimmer Temperature Motor Speed Controller for Heat Controller on Electric Stoves, Water Heaters, Light Dimmer on Lamps,etc

guys this is a 220 volts SCR controlled voltage regulator module for light dimming motor speed controlling and thermal stamp it's available on Amazon for three hundred and forty rupees which is five dollars and fifty cents it's pros are first it's rated power is two thousand volts second it's weight is just 41 grams third the manufacturer has used in the standard quality fr4 EC meter the fr for PCBs are superior in three ways a better insulation be good strength to weight ratio and see its ability of being temperature resistant which means that the PCB won't get burned easily now the things that I don't like about this circuit are they have used just one SCR and a boasting that the circuit can handle a load of up to 2,000 watts personally I don't think that a single SE ur can handle that much amount of burn for longer times the second is the voltage regulation range which is 50 volts to
