The technical solution adopted in the utility model is: DC UPS, comprise charging device and energy storage device, the input of described charging device connects electric main, one output connects DC load, its another output connects energy storage device, and this charging device is for being converted into low-voltage DC by electric main; The output of described energy storage device connects DC load.
Described energy storage device is storage battery.
The input voltage of described charging device is AC220V, and the output voltage of described charging device and energy storage device is the DC12V for camera power supply.
The beneficial effects of the utility model:
The utility model uninterrupted power supply only consists of charging device and energy storage device, inverter and required transformer and the rectifier of DC load in traditional UPS have been omitted, therefore lacked one time electric energy transfer process, reach the effect saving production cost with electric energy loss, be also convenient to DC load and directly power; In addition, charging device connects respectively main road and bypass, and after civil power disconnects, main road is switched to the battery powered response time of bypass and shortens, and effectively protects the safety of load.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is the theory diagram of traditional uninterrupted power supply and load;
Fig. 2 is the theory diagram of the utility model uninterrupted power supply and load.
Embodiment
Shown in Fig. 2, DC UPS, comprises charging device 1 and energy storage device 2, the input of charging device 1 connects electric main, one output connects DC load 3, and its another output connects energy storage device 2, and this charging device 1 is for being converted into low-voltage DC by electric main; The output of energy storage device 2 connects DC load 3.
Wherein, energy storage device 2 of the present utility model is storage battery, and the input voltage of charging device 1 is AC220V, and the output voltage of charging device 1 and energy storage device 2 is the DC12V for camera power supply.
The operation principle of the utility model uninterrupted power supply is, when civil power, inputs when normal, and by AC220V, DC12V's charging device 1 of main road after transformation, rectification conversion powers to camera, and it is also to charge in batteries; When commercial power interruption (accident interruption), there is storage battery to provide DC12V for camera.
The utility model uninterrupted power supply only consists of charging device 1 and energy storage device 2, inverter 4 and required transformer 5 and the rectifier 6 of DC load 3 in traditional UPS have been omitted, therefore lacked one time electric energy transfer process, reach the effect saving production cost with electric energy loss, be also convenient to DC load 3 and directly power; In addition, charging device 1 connects respectively main road and bypass, and after civil power disconnects, main road is switched to the battery powered response time of bypass and shortens, and effectively protects the safety of load.
The foregoing is only preferential execution mode of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection range of the present utility model.
