Q:Room precision air conditioning power supply where to take electricity? (Is directly take the electricity in the electricity distribution cabinet or take the UPS back-end power) or both

Depending on the importance of the application of the engine room, the cabinet power density and cooling the way: If the application of the engine room is very important, the air conditioning power supply requirements will be high, you can use the mains + UPS way power supply, otherwise you can use the main power supply; if the water cooling unit can increase the capacity of the storage tank To increase the cooling of the backup time, power supply requirements can be reduced accordingly. If the power density of the cabinet is very large, and the application is very important, it is better to use UPS power supply.

Q:What is the difference between the UPS power supply and the frequency machine?

Frequency machine is China's argument, that is, with the frequency transformer. You think, 1000 liters of water, with 1000 liters of buckets come down, water fee, but once get. So the bucket is also expensive. There are more impurities in the water. Frequency machine is a high frequency of small transformers to simulate the frequency. Like 1000 liters of water, with 1 liter of the bucket down, down 1000 times to meet the water needs. Still can not spill water, the technical difficulty is high. The bucket is small, cheap, and the water is better. Upstairs that high-frequency for the computer, a total frequency machine performance is good, this is a misunderstanding. This is because the high-frequency technology involves real-time monitoring of electricity to add what energy is more difficult, many manufacturers do well, so become impatient impact (water poured out). Frequency machine itself is a large harmonic source, damage equipment, but also electricity, no energy. So, said the frequency machine than the high-frequency machine is good, but for the domestic technical capacity of the existing point of view. Put it bluntly, that is, domestic high-frequency power technology is not mature. Small Japanese high-frequency technology no such problem, power, but also anti-harmonic.

Q:With 10KS UPS backup for an hour. How much AH battery is used. How many only. Speed back down. Load is 8KW .. DC is 240

Battery capacity ah = load capacity / 0.7 (discharge factor) / efficiency (depending on the efficiency of the UPS you buy) / battery voltage * emergency time (hours) because you did not tell me the specific load and your UPS efficiency, only Your own calculations.

Q: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.

Q: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.

Q:Listen to the market suppliers themselves, such as C3KS, actually about 2K more than one day is how the matter?

Note whether the UPS is online or backup. What is the quality of the battery? There is no communication function. Conversion efficiency refers to the ratio of the UPS input rated current to the final output value. The closer the better.

Q:Uninterruptible power supply UPS advantages

The main advantage of uninterruptible power supplies is its uninterrupted power supply capability. When the mains AC input is normal, the UPS rectifies the AC rectifier into DC power, and then converts the DC into a stable impurity-free alternating current, which is used for the post-stage load. Once the mains AC input exception, such as undervoltage or power outage or the frequency is abnormal, then the UPS will enable the backup energy - battery, UPS rectifier circuit will be shut down, the corresponding, will the battery DC into a stable Impurity of the alternating current, continue to use the post-class load. This is the UPS uninterrupted power supply origin.

Q:Uninterrupted power ups battery and electric car battery What is the difference, can replace

Dear Lvyuan Electric Car User: Hello! Can not be replaced. Thank you for your message and wish you a happy life!

Q:Small ups uninterruptible power supply, you can add an external battery?

Hello, low-power UPS you want to take a large battery, then the following consequences may occur 1. battery charge dissatisfaction, the battery is not a long time to scrapped, because the small machine does not have a separate charge version, can not meet the battery charge. 2. With small and medium size batteries, may have a long charge after the discharge time, if the voltage instability, frequent power failure, the battery will be scrapped in advance. 3. Discharge when the battery trickle discharge, the battery scrapped. In summary, it is recommended not to change other models of the battery, or for UPS. Mountain has a huge MT500 charging capacity can have a long delay, you can outside the large battery. I hope my answer can help you, look forward to your praise.

Q: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 ~
