Embodiment 1
[0018] Once the 220V power input socket is connected to the 220V AC mains, no matter whether the host is turned on or not, the ATX power supply will always have a set of +5VSB standby voltage output 5V (maximum current 800mA), which is used for the power monitoring unit of the PC motherboard, network communication interface, and system clock. Chips, etc. are used to prepare for the ATX power supply to start. When the PC is not started, PW-0K is the control signal output by the ATX power supply for the motherboard to detect whether the power supply is ready, and it is zero-level in the standby state. When the PC starts up, if the motherboard works normally, the PW-0K controlled startup delays 100-500ms and outputs a 5V high level, and the computer starts up and works normally. When the computer is turned off, the PW-0K output is zero level.
[0019] refer to figure 1 and figure 2 , when the host computer is turned off, the PW-0K port outputs zero level, the transistor...
Embodiment 2
[0021] Because the print heads of some printers currently in use need about 10 seconds to reset, a circuit with a delay of 15-20 seconds is designed to support the power supply of the controlled 220V power socket to delay power failure for 15-20 seconds.
[0022] see figure 2 , when the host computer is turned off, the PW-0K port outputs zero level, the transistors T2 and T1 are cut off, the relay J has no current passing through, its double contacts are disconnected, and the controlled 220V power socket has no power. When the host computer is started and the main board is detected to work normally, the PW-0K port outputs a 5V high level, and through the diode D2, on the one hand, the capacitor C2 is charged, and on the other hand, the voltage is provided to the triode T2 and the n base, and the triode T2 and T1 are turned on. The relay J works with electricity, the contacts are closed, the controlled 220V power socket outputs 220V AC, and the external equipment connec...
Embodiment 3
[0024] Some computer ATX power supplies, if they have a plug socket in addition to the 220V power input socket, then just cut off the original power wiring of the plug socket and connect it to the relay J contact of the energy-saving control circuit.
[0025] see image 3 , the installation position of the controlled 220V power socket is marked in the figure. It's just that when using it, the adapter line should be a plug that matches the plug socket. If the computer has only one monitor and no other peripherals, you can directly plug the power plug of the monitor into a controlled 220V power outlet. If there are other external devices, you can insert the power plug of a multi-power socket board into the controlled 220V power socket, and then insert the peripheral power plugs into the multi-power socket board one by one.
