With reference to Fig. 1, the computer power supply device of band Energy Saving Control comprises power input socket 1, controlled source socket 2, computing machine TAX power supply 3 and energy-saving control circuit 4.
With reference to Fig. 2, energy-saving control circuit 4 comprises base resistance R1, the compound first continuous triode T1 and the second triode T2 and load-relay J thereof, the PW-OK signal of computing machine TAX power supply is connected to base resistance R1 by diode D2, a pair of normally opened contact of relay J be serially connected in respectively that live wire L between power input socket 1 and the controlled source socket 2 goes up and power input socket 1 and controlled source socket 2 between zero line N on.
Relay J is connected to delay circuit.Delay circuit is made of resistance R 2 and capacitor C 2, and resistance R 2 and capacitor C 2 series connections are between base resistance R1 and the power ground.The delay time of delay circuit is 15-20s.
Below by embodiment the concrete course of work of basic circuit is explained.
Embodiment 1
In case the 220V power input socket inserts the 220V electric main, no matter whether main frame starts shooting, the ATX power supply will have one group+5VSB standby voltage output 5V (maximum current 800mA) all the time, for uses such as PC motherboard power supply monitoring unit, network communication interface, system clock chips, for the ATX power initiation is prepared.When PC was not activated, to be ATX power supply output detected whether ready control signal of power supply for mainboard to PW-OK, and holding state is down for putting down zero point.When PC started, as the mainboard operate as normal, the PW-OK controlled starting postponed 100-500ms output 5V high level, computer starting operate as normal.Behind computer shutdown, it is flat that PW-OK is output as zero point.
See figures.1.and.2, under the main frame closed condition, PW-OK port output is flat zero point, triode T2, T1 by, relay J does not have electric current to pass through, its pair contact is an off-state, controlled 220V supply socket does not have.When main frame starts, detect the mainboard operate as normal, PW-OK port output 5V high level, voltage is provided for triode T2 and T1 base stage, triode T2 and T1 conducting, the charged work of relay J, contact adhesive, controlled 220V supply socket output 220V alternating current connects the charged work of external unit thereon.Behind computer shutdown, the PW-OK port voltage is that zero point is flat, the relay J dead electricity of energy-saving control circuit, and two contacts disconnect, and controlled 220V supply socket outage connects also just outage automatically of equipment thereon.
Use the computer power supply device of band Energy Saving Control of the present invention, it is just passable that the power switch of the display of computing machine, printer, sound system etc. is in connection status always.
In the circuit, relay J is operating voltage 5V, and working current 50mA, contact connecting-disconnecting function are the double-contact small-sized DC relay of 250V, 10A.All the other component parameters are that T1:8050, T2:9014, D1:IN1001, D2:IN1001, C1:470uF10V, C2:1000uF5V, R2:1K, R1:100K. are because the dispersiveness of component parameters, so when the actual selection circuit parameter, adjust R1 numerical value to satisfy the requirement of shutdown time-delay power supply.
Because at present the printhead of some printer that uses needs 10 seconds left and right sides time to reset, the circuit that has therefore designed a time-delay and be 15-20 second is supported controlled 220V supply socket power supply to delay 15-20 to cut off the power supply second.
Referring to Fig. 2, under the main frame closed condition, PW-OK port output is flat zero point, triode T2, T1 by, relay J does not have electric current to pass through, its pair contact is an off-state, controlled 220V supply socket does not have.When main frame starts, detect the mainboard operate as normal, PW-OK port output 5V high level, through diode D2, capacitor C 2 chargings on the one hand, voltage is provided on the other hand triode T2 and T1 base stage, triode T2 and T1 conducting, the charged work of relay J, contact adhesive, controlled 220V supply socket output 220V alternating current connects external unit work thereon.Behind computer shutdown, the P0-OK port voltage is that zero point is flat, owing to discharge with triode T2, T1, so triode T2, T1 still are in conducting state, so relay J has electric current to flow through, the contact is adhesive still, controlled 220V supply socket energising.The numerical value of adjusting capacitor C 2, base resistance R1 and resistance R 2 just can be adjusted the time of delay cut-off, and delay time generally is adjusted into 15-20s.Whole energy-saving control circuit circuit board size is less, and it is promptly passable directly to be fixed on the inner correct position of ATX power supply.
Embodiment 3:
Some computer ATX electric power if itself except having the 220V power input socket, also have an edge connector, so as long as the original power supply wiring of this edge connector is cut off, is connected on the relay J contact of energy-saving control circuit just passable.Referring to Fig. 3, controlled 220V supply socket installation site is understood in the figure acceptance of the bid.Patchcord is for just passable with the plug of edge connector coupling when only being to use.
If computing machine only is with a display not have other peripheral hardwares, it is just passable the display power supply plug directly can be inserted controlled 220V supply socket.If also have other external units, the attaching plug of a multi-input socket plate can be inserted controlled 220V supply socket, it is just passable then the peripheral hardware attaching plug to be inserted the multi-input socket plate one by one.
