Embodiment
With reference to Fig. 1, band, for the Energy Saving Control power-supply device on computing machine, 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, compound the first connected triode T1 and the second triode T2 and load-relay J thereof, PW-0K signal of computing machine TAX power supply is connected to base resistance R1 by diode D2, and a pair of normally opened contact of relay J is serially connected in respectively on the zero line N on the live wire L between power input socket 1 and controlled source socket 2 and between power input socket 1 and controlled source socket 2.Relay J is connected to delay circuit.Delay circuit consists of resistance R 2 and capacitor C 2, and resistance R 2 and capacitor C 2 series connections are between base resistance R1 and power ground.The delay time of delay circuit is 15-20s.
Below by embodiment, the specific works process of basic circuit is explained.
Once 220V power input socket access 220V electric main, no matter whether main frame starts shooting, ATX power supply will have one group+5VSB standby voltage output 5V (maximum current 800mA) all the time, for PC motherboard power supply monitoring unit, network communication interface, system clock chip etc., for ATX power initiation is prepared.When PC is not activated, PW-0K is that ATX power supply output detects the whether ready control signal of power supply for mainboard, under holding state for putting down zero point.When PC starts, as mainboard normal operation, PW-0K controlled starting postpones 100-500ms output 5V high level, computer starting normal operation.After computer shutdown, it is flat that PW-0K is output as zero point.
See figures.1.and.2, under main frame closed condition, PW-0K port output is flat zero point, triode T2, T1 by, relay J does not have electric current to pass through, its pair of contact is off-state, controlled 220V supply socket does not have electricity.When main frame starts, the normal operation of detection mainboard, PW-0K port output 5V high level, voltage is provided to triode T2 and n base stage, triode T2 and Tl 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.After computer shutdown, PW-OK port voltage is that zero point is flat, the relay J dead electricity of energy-saving control circuit, and two contacts disconnect, controlled 220V supply socket power-off, the equipment thereon of connecing is also with regard to auto-breaking.Use band of the present invention for the Energy Saving Control power-supply device on computing machine, the power switch of the display of computing machine, printer, sound system etc. just can in connection status always.In circuit, relay J is operating voltage 5V, working current 50mA, and contact connecting-disconnecting function is the double-contact Miniature direct current relay of 250V, 10A.All the other component parameters are that T1:8050, T2:9014, D1:IN1001, D2:IN1001, Cl:470uF10V, C2:1000uF5V, R2:1K, R1:100K. are due to the dispersiveness of component parameters, so when actual selection circuit parameter, adjust Rl numerical value to meet the requirement of shutdown time delay power supply.
Because the printhead of some printer using at present needs 10 seconds left and right time, Song resets, and has therefore designed the circuit that a time delay is 15-20 seconds and has supported controlled 220V supply socket power supply to delay power-off in 15-20 seconds.
Referring to Fig. 2, under main frame closed condition, PW-0K port output is flat zero point, triode T2, Tl by, relay J does not have electric current to pass through, its pair of contact is off-state, controlled 220V supply socket does not have electricity.When main frame starts, the normal operation of detection mainboard, PW-0K 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 n 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.After computer shutdown, PW-0K port voltage is that zero point is flat, due to triode T2, n electric discharge, so triode T2, n still in conducting state, so relay J has electric current to flow through, contact is adhesive still, controlled 220V supply socket energising.Adjust the numerical value of capacitor C 2, base resistance R1 and resistance R 2 and just can adjust the time of delay cut-off, delay time is generally adjusted into 15-20s.Whole energy-saving control circuit circuit board size is less, is directly fixed on the inner correct position of ATX power supply passable.
Embodiment 3:
Some computer ATX electric power, if itself is except having 220V power input socket, also with 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, figure acceptance of the bid understands controlled 220V supply socket installation site.When just using, patchcord is that the plug that mates with edge connector is just passable.If computing machine is only with a display there is no other peripheral hardwares, display power supply plug directly can be inserted to controlled 220V supply socket just passable.If also have other external units, the attaching plug of a multi-input socket plate can be inserted to controlled 220V supply socket, then external power plug is inserted to multi-input socket plate one by one just passable.
