The power supply the utility model proposes comprises: housing, its front end face is provided with an on & off switch and a light source that can indicating equipment work, and end face is provided with an interface by an electric wire access electrical network and a protection equipment exempts from the input insurance that power network disturbs thereafter; By after the electricity conversion on electrical network for distribution, more than one accessory power outlet and the power supply terminal of quantity; The warning light source that whether equipment works, quantity is more than one that instruction is connected with power supply terminal; Be arranged on the first circuit board for control switch key and light source in housing; For controlling the second circuit board of power supply terminal and warning light source; For power supply unit provides the electric pressure converter of required voltage; Line voltage is converted to the transformer of voltage available; Regulate the tertiary circuit plate of required voltage by controlling line voltage, and a storage battery that required electric energy is provided in the situation that having a power failure.
Compared with prior art, the utlity model has following advantage:
AVR(automatic voltage regulator in this power supply) part can regulate the voltage of its place network; the in the situation that of camera damage or short circuit; can only cut off the voltage of camera; thereby protection whole system; and, in the time having a power failure, can safeguards system work in required time or in certain hour.
Without exchanging the accessory of output plugs and 12 volts of DC output end or plug and realize power supply in the case of safety-protection system required 220 volts being installed.
Without being an adapter of the extra installation of camera, and, in the situation that certain camera goes wrong, be other camera normal power supply.
Prevent the damage causing because of electric power networks abnormal electrical power supply.
For safety-protection system provides the operating voltage of coupling.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in detail, wherein:
Fig. 1 is the front view that the utility model proposes power supply;
Fig. 2 is the rearview that the utility model proposes power supply;
Fig. 3 is the cut-away view that the utility model proposes power supply.
Embodiment
In the accompanying drawings, identical Reference numeral represents respectively identical parts.
As shown in Figure 1 to Figure 3, the power supply 1 that the utility model one embodiment proposes adopts cuboid shell.The light source 4 whether front surface of housing 2 is provided with on & off switch 3 and indicates power supply 1 working.Open or close light source 4 by trigger switch key 3.It is luminous that light source 4 adopts LED to carry out.
For power supply 1, be linked in housing 2 through interface 5 from electrical network by an electric wire.Housing 2 is provided with input insurance 6, exempts from the interference of problem due to electrical network for the protection of equipment.
Power supply 1 has two accessory power outlets 7.Two accessory power outlets 7 are for being video cassette recorder (DVR) and watch-dog power supply.Accessory power outlet 7 is positioned on the rear surface of housing 2.
The power supply terminal 8 of power supply 1 is positioned on the rear surface of housing 2 and is adjacent with accessory power outlet 7.The quantity of power supply terminal 8 can based on adopt power supply 1 system scale and change.Each power supply terminal 8 of the power supply 1 the utility model proposes has adopted electronic insurance.Therefore,, in the situation that going wrong, insurance can be cut off the supply of electric power of its line road, the first-class equipment of making a video recording.Warning light source 9 is located at the top of power supply terminal 8.In the time that power supply terminal 8 is cut off, warning light source 9 also can extinguish.Warning light source 9 indicates the equipment connecting from power supply terminal 8 to power supply terminal whether to have electricity, so more easily grasps the situation of equipment.
When the first-class equipment connection of shooting is on power supply terminal 8 time, without by any adapter, directly connect.
On power supply 1, being provided with can control switch key 3, first circuit board 10 and the second circuit board 101 of light source 4, accessory power outlet 7 and power supply terminal 8.
The electric pressure converter 11 configuring for required voltage being provided to the first-class equipment of shooting adopts a kind of SMSP(on-off mode power supply) adapter.The electric pressure converter 11 of another kind of form is AC/DC transducer.
Tertiary circuit plate 102 in the power supply the utility model proposes, can provide required voltage for the system that adopts line voltage type power supply.When power failure, normally work for the first-class assembly of shooting that makes to be connected with equipment, in tertiary circuit plate 102, be provided with a transducer.Except being provided with tertiary circuit plate 102, also can charge to storage battery 13 to electrical network in the situation that at equipment connection, storage battery, at any time in preparing the state of power supply, ensures power supply in time when power failure.
The storage battery 13 that power supply 1 adopts is dry type storage batterys of service free.
The power supply 1 the utility model proposes can be arranged on CCTV(closed-circuit television) in safety-protection system, for security protection camera, monitor and video cassette recorder provide 220 volts of required alternating voltages of work and the power supply of 12 volts of direct voltages.The power supply 1 the utility model proposes can be 1 video cassette recorder, 1 monitor and 16 security protection camera power supplies simultaneously.According to user's demand, the operating time after power-off can extend by increasing storage battery 13.Simultaneously, because power supply 1 has adopted automatic voltage regulator (AVR), can regulate the voltage of place electrical network, and, in situations such as going wrong, be short-circuited at camera, the voltage that only cuts off the camera going wrong just can ensure the normal work of whole system.
From electrical network to power supply, 1 electric current, by the rear arrival tertiary circuit of transformer 12 plate 102, directly arrives socket 7 in the time that voltage is suitable, when improper, after regulating, exports again.Therefore, accessory power outlet 7 can be continuously provides 220 volts of Alternating Current Power Supplies for video cassette recorder and monitor.Meanwhile, in the time connecting electrical network, be that storage battery 13 charges.The in the situation that of power-off, power supply can obtain electric current from storage battery 13, continues as the system power supply that power supply 1 connects.Owing to being provided with SMPS adapter or AC/DC electric pressure converter 11 in power supply, therefore, can provide 12 volts of direct currents for power supply terminal 8.Can observe the camera circuit that is connected with power supply and whether the power supply of camera has occurred problem by warning light source 9.If there is problem, can cut off circuit that power supply terminal 8 connects and the voltage of camera by insurance.After the circuit connecting until power supply 1 or the problem of camera solve, power supply terminal just can continue power supply.
Although the utility model is described according to specific example, but these examples are only exemplary, instead of restrictive, on the contrary in the case of do not depart from by following claim state and the utility model spirit of limiting, can make various adjustment, amendment and replacement.
