Craftsman 17090 19.2 volt C3 Cordless 1/2 inch Impact Wrench Review Part 2
Bell flow control with power switch
At present, the fax machine, answering machine, cordless telephone terminal equipment such as telephone users every day to wait a long time in the state. In a long idle time, 220V power supply is always added to the machine, the machine's circuit are 24 hours. This not only wasted energy, can also cause temperature, component aging, the machine easy to damage, easy to produce the consequences of fires.
This paper describes a bell-day relations of power flow control, which uses the signal to start ringing telephone user terminal equipment, 220V power supply. For example, telephone answering machine equipped with this switch is closed, when a telephone ring signal when the power switch will be triggered in the ringing telephone answering machine connected to 220V power supply and begin to work; when the answering machine pick ? message? hang completed, the power switch to cut off 220V power supply, so answering machine power state without waiting.
Work flow control ring power switch circuit shown in Figure 1. Is a fax machine as an example to illustrate the working principle of this switch. Into side a, and b is the Authority to answer the phone lines, out-side a, and b then fax. When a ringing signal comes in, the ringing signal through the C3, C4, R4, after rectification by the D11 ~ D14, will produce a certain voltage on C2. C2 the voltage delivered by D15 IC of , side, IC's , terminal will turn, D16 turn, to the C5 charge, SCR conduction, connected to the socket on the fax machine connected to 220V AC, and work. When the fax machine pick up the work, through the D1 ~ D4, C1 constitutes a channel, receive a fax signal. Work in the fax, C1 have voltage, the voltage through R3, D6 supply IC of , side, to keep SCR conduction, the total outlet 220V voltage, time does not matter whether the ring signal already.
When the fax is concluded, the end of a and b is equivalent to open, then there will not be on the voltage of C1, IC is not working, SCR end, no outlet 220V voltage, fax back to the waiting state. To send a fax, you can just click the K1.
Component selection circuits are used in all the diodes 1N4007. D5 green light-emitting diodes, light work, not work off. D17 red light-emitting diode, the work does not light, wait for the state of light. Use micro-current trigger SCR SCR 2A600V. Use optocoupler IC MOC3041. Other components are marked according to the schematic on the parameters of selection.
Commissioning and use as long as installed by circuit components do not need to use debugging. Circuit D1 ~ D4, C1, R2, R3 self-holding circuit for the work, if the self-holding is not good, can be adjusted R2, R3 size. As long as signaled by Figure 2 can be connected and used.
The power switch can be installed on both the fax machine, answering machine, cordless phone's chassis is also made according to Figure 2, an independent product.
Cordless phone using the power switch, only to call when the automatic power-up work, auto power off after the call ends, and thus overcome the cordless phone 24h heat problem within the work, but also to prevent a neighbor was using sub-machine synchronization Daoda your phone.
