A heating wire regulator for an electronic mat is provided to prevent fire accidents by disconnecting an excessive current from the electronic matrix and detecting a disconnection of the heating wire. Power supplies(10,10') supply power to a heating wire controller. Rectifying units(20,20') convert an AC voltage to a DC voltage. Switching controllers(30,30') control the power which is supplied to a heating wire of an electronic mat. An EMI(ElectroMagnetic Interference) filter shields an EMI. Temperature setting units(50,50') set a temperature for the electronic mat. A detector detects an excessive current, an overheat, and a disconnection of the heating wire. Operation lamps(70,70') display an operation state of the heating wire controller. A heating wire connector is connected to the heating wire which is made of a heat radiating material. Central processors(90,90') control the signals from the detector and transmit the controlled signal to the operation lamp. A voltage supply controls the voltage which is supplied to the central processor. |
