Electromagnetic Heater Temperature Control

Electromagnetic heater has two soft-start signal line, the two signal lines are not positive and negative points, as long as the two signal lines are connected then the electromagnetic heater can work, if the two signal lines are not connected Pass on the case of disconnection, then the electromagnetic heater does not work. Electromagnetic heaters are in this way to control the temperature.

The two soft-start signal line is used to connect the thermostat on the normally open switch, in the case of no power, the thermostat inside is not connected, that is, when the electromagnetic heater is broken, So it is not working. When the power inside the thermostat inside the switch will normally open, then this time the two soft-start signal line is connected, so this time the electromagnetic heater will start working heating.

When the temperature reaches the set temperature, the thermostat inside the normally open switch will be disconnected, then the electromagnetic heater to stop working and heated, when the temperature is lower than the set temperature, the thermostat inside will be connected , So that the electromagnetic heater and then continue to work heating. So the electromagnetic heater is a constant temperature heating method.
