How to calculate the power regulator for heaters?

Stanislav asks:
Hello, I need to connect two serial circuits of ceramic infrared heaters to one power regulator, NT-73 heaters (uborg company) power 360 + -10% W, operating voltage 73 + -10% V each. The number of heaters is 6 pieces, 3 pieces in each circuit. Need to know the power controller specifications?

The answer to the question:
Hello! Need to add power, do you want from one controller or from different ones? Do you need a power regulator? With smooth adjustment? Heaters often supply thermostat, i.e. they turn on fully and turn off when the set air temperature is reached.

If you need smooth adjustment and you are going to power everything from one regulator, then you need a power regulator (triac) for:

360 * 6 = 2160 watts.

Those. buy 3-3.5 kilowatts, the triac must be on the radiator, I warn you because power regulators are sold in stores in the form of a scarf with parts, without a radiator. In this state, they pull from the power of 500 watts.

If you want them to turn on and off completely - take a temperature controller, for example, CRT-02 from Euroavtomatika or any other, you can also connect it all through a power outlet, for example, use a smart socket from Novatek model EM-126T -1".
