This decompression delayer operation principle describes as follows:
After being powered on by power input port, be supplied to DC power supplier (DC power supplier of 12V) and alternating current 220V bridge rectifier module respectively via electric current and voltage protection module.
DC power supplier is powered to power-up time delay circuit, and this power-up time delay circuit starts.Control the second drive circuit of rear end to coil electricity, the delayed actuating of relay after power supply time delay 1S, it is often opened output contact and closes and maintain, until this power-up time delay circuit loses power supply, at once disconnects.
Control to high-voltage capacitance storage electric energy through switch triode after the rectification of bridge rectifier module.
After the DC power supplier of 12V powers on, also to power energy storage to low-voltage capacitance simultaneously, the electricity that this low-voltage capacitance stores can when the unexpected dead electricity decompression of device, continue maintenance 555 time-base circuit, counting circuit, decoding circuit, digital display module and decompression time-delay relay its first drive circuit and second drive circuit etc., the normal work in a period of time.
