In general, metal film resistors use epoxy paint (ignition and ignition upon overloading), but metal film resistors used in the present invention do not ignite when overcurrent, overvoltage and overloading are caused by using Silicon Dioxide Resin , It can be safely used at high temperatures.

The overheat prevention sensor 360 may be provided to shut off the power applied to the heat generating means 350 when the heat generating means 350 rises above a predetermined temperature to prevent a safety accident. It is not preferable.

The controller 100 measures the voltage supplied to the soot reduction unit 200 and supplies power to the soot reduction unit 200 to operate the soot reduction unit 200 when the voltage is equal to or higher than the set voltage.

When the voltage is supplied to the gate input terminal of the FET1 switching device 130, Power source is supplied to the soot reduction unit 200 through the P / J2 output power source line 186 while the potential difference between the power source SOURCE and the drain DRAIN changes to 0 volt.

The LED2 power lamp 151 is turned on immediately when the P / J1 input power line 180 is connected.

At this time, the LED 3 microcomputer operation lamp 152 is also turned on at the same time.

The microprocessor IC2 120 continuously checks the input voltage and, after a few seconds, the LED1 output voltage display device 150 indicates the voltage.
