FAQ
- 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 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.
- Online power ups on the line power does not light how to do
- UPS has no normal operation, if there is normal operation, the indicator light does not shine, may be plug on the plug loose! If the UPS is not running, it may not be turned on or the power button is broken. Also may be UPS internal failure, if they can not solve, it is recommended to repair! The The Pearl River Delta region to buy, repair can find our company!
- Guiqiu a UPS power supply ads, to be creative?
- Power out I am not afraid, stopped I have it in the back of it put a UPS power supply picture or let a person holding a UPS to take a picture behind the back ~ ~ ~ hope to comment on a best answer ~
- What construction tools are required for UPS power supply installation
- Because the battery is a DC nature of the short circuit, the consequences are very serious.
- What are the hazards of the harmonics generated by the UPS power supply?
- Suppression of harmonic methods Method 1, the use of 6-pulse UPS + active harmonic filter, input current harmonic <5% (rated load), the input power factor of 0.95. This configuration, although the input index is very good, but the technology is still immature, there are false compensation, over compensation and other issues, leading to the main input switch error trip or damage and other phenomena; THM active harmonic filter technology defects Method 2, the use of 6-pulse UPS + 5 harmonic filter, if the UPS rectifier device for the three-phase full-controlled bridge 6-pulse rectifier, rectifier generated by the harmonics of all harmonics nearly 25-33% plus 5 harmonic Wave filter to reduce to 10% or less, the input power factor of 0.9, can be partially reduced harmonic current on the power grid hazards. This configuration, the input current harmonics are still too large, the generator capacity requirements for the ratio of 1: 2 or more, and there lead to abnormal increase in the output of the hidden dangers; Method 3, the use of phase-shifting transformer +6 pulse rectifier false 12 pulse program, its composition consists of two 6-pulse rectifier ups into: Method 4, the use of 12-pulse UPS + 11 harmonic filter, if the UPS rectifier device for the three-phase full control bridge 12 pulse rectifier, plus 11 harmonic filter reduced to 4.5% or less, can basically completely eliminate the harmonic Current content on the power grid hazards, the price is much cheaper than the active filter.
- What are the requirements for the UPS power supply installation site?
- 3.UPS ambient temperature should be kept between 0 degrees to 40 degrees. 4. If the machine is disassembled at low temperature, there may be water droplets condensation phenomenon. 5. Please put the UPS in the mains input socket, so that when the emergency pull out the mains input plug, cut off the power
- What is the room ups?
- From the use of information society, UPS is widely used in information collection, transmission, processing, storage to the application of all aspects, the importance of information applications with the increasing importance of increasing.
- The server is IBM X3610 power is 600W should choose the kind of UPS power supply is better.As long as the sudden power failure to ensure normal shutdown on the line.
- With the mountain 1K on-line enough! If the mains voltage stability, then, do not have a voltage regulator with the UPS power supply, you can buy Hills TG1000 But suggest that you use the MT1000 although slightly more expensive, after all, there is a regulator function, as a server, must provide the most effective support!
