I now have to design a set of UPS capacity of about 600 cameras, 40 LCD monitors (19 inches), 14 hard disk recorders, a matrix. There are 50 pairs of optical machines. Who knows this, the trouble told me about how much need to be equipped with the UPS.
The current backup UPS, it should be 500VA / 200W reserve 10 minutes or so, according to 100W, then use a 30 minutes or so.
Can be purchased as follows:
1) When selecting a UPS, the user should take into account the individual requirements such as the size of the load, the characteristics of the load device, the importance of the load device, and the degree of impact of the adverse power on the load.
2) first of all need to understand the need for back-up, online, online interactive products such as performance considerations.
3) the most important to pay attention to equipment power, distinguish the actual power and rated power, there is the need for power to delay time to distinguish.
4) in the purchase should pay attention to equipment is not an inductive load, to test the equipment is equipped with centralized or decentralized
And other technologies to the fifth: the final consideration is also must be considered is to buy UPS to consider their own brand and after-sales service, which is the most important!
UPS is the abbreviation of English Uninterruptiable Power Supply, translated as uninterruptible power supply. From the 20th century, 60 years of rotary generators to the current development of a certain degree of intelligent all-electronic circuit, it is with the electronic technology, especially power devices and automatic control technology and the rapid development of mature. Its basic functions are:
Power interruption power supply, can not intermittently power supply;
Always provide high-quality AC power to the load, to stabilize. Steady frequency. Suppress the surge. Spike. Electric noise. Compensation voltage subsidence. Long-term low pressure and other factors interfere with.
The key of this camera is too wide, a few W to several hundred watts have.
40 LCD, if it is LED, also 2KW. If it is old, about 4KW
DVR is also a 200-300W * 14 = 4.3KW
Optical do not have to forget, too small.
Matrix ... no specific parameters.
If it is a terminal camera, each about 3-5W, probably a total of 20-30KVA is enough.
?
If it is a film camera (estimated not, or else 600 too much):
The key is that even 600 cameras every 20W, have 12KW. 20KVA if you need insurance.
If it is 200W, you need 200KVA.
And the camera is not also need to have a matching mobile shelves, if there is a motor, it is estimated how to use hundreds of KVA only safe.
If there are still lights: a camera can take 2.6KW lights, it is estimated that the astronomical figures.
Wow, you do not understand ah, you should detail the rated power of each device, add up on the line, while leaving a little margin
