When temperature sensing signal judges the temperature anomaly of electric power output equipment 5, i.e., stopped by IOA1 pin controlling switches circuit 24 defeated
Go out the connecting interfaces of predetermined voltage VCC to second 12, make to stop power supply to electrical equipment 3, and make reminding module 13 produce a representative
The abnormal prompt signal of temperature anomaly state, for example, make the light emitting diode of reminding module 13 persistently flash, to remind user
Note.
Specifically, as shown in figure 5, on-off circuit 24 has the third transistor switch Q2 of an emitter grounding, a gate
Collector with third transistor switch Q2 electrically connect, drain receive predetermined voltage VCC and source electrode and the second connecting interface 12+hold
4th transistor switch MA2 of son electrical connection, one is electrically connected to the IOA1 pins and third transistor switch Q2 of control unit 20
Base stage between resistance R11, and one be connected electrically in resistance R12 between the drain of the 4th transistor switch MA2 and gate.
Whereby, when control unit 20 judges that the temperature of electric power output equipment 3 is normal according to the temperature sensing signal, its warp
The base stage that one high levle signal switchs Q2 to third transistor is exported by IOA1 pins so that third transistor switchs Q2 and the 4th
