Uninterruptible power supply UPS advantages
Figure 1 is a typical UPS block diagram. Of course, UPS's uninterrupted power supply time is not infinite, this time is subject to the battery itself to store the size of energy. If the AC power outage occurs, then the UPS battery power in the valuable time, you need to do is to quickly restore the AC, such as the use of standby AC circuit, enable the oil generator, it is not, we can only save the emergency, save the fruits of labor, wait AC power to normal and then continue.
s the UPS power supply only in the battery when the power outage or the mains voltage is below the input range?
This statement is not precise enough. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter zero switching method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS is the abbreviation of "Uninterruptible Power System", which can ensure that the computer system will continue to work for a period of time after the power outage so that the user can save the file so that the user will not cause the power outage Affect work or loss of data.
Petrochemical industry, two UPS dual-machine hot backup power supply for the instrument, this part of the load how to calculate the need to account for the total capacity of the load?
UPS for the instrument power supply need to join the load!
Such as the problem - how much battery can be configured to meet the two hours 1. What is the formula can be calculated? 2. What is its DC voltage? How much battery should it be?
Mountain 20K two hours need to be equipped with 32 100AH battery. China's more well-known battery brands are Panasonic, Yuasa, Ai Peisi, Hills and so on!
Equipment room equipment as follows IBM X3650 M2 server one Rated voltage 100-127 / 200-240v Rated current of 7.8 / 3.8A IBM X3650 server one Rated voltage 100-127 / 200-240V Rated current 10A / 5A Ordinary switch a model parameter is unknown DVR A model parameter is unknown Mainly to ensure that the server can be power supply, the external power supply can be guaranteed to disconnect more than half a day can hope that the list of models, and the number of battery I am not very understanding of this, I hope to be able to explain in detail.
The choice of UPS power supply room is based on the equipment required by the engine room, metaphor is equipped with monitoring, servers, switches and the like are capacitive load, buy UPS power supply when you choose a high frequency machine on it. If it is a printing press, automation equipment. Automatic access control system and so on belong to the inductive load, need to match the power frequency UPS power supply. Select the appropriate UPS according to the size of the load when selecting UPS. The load is generally 60-70% of the UPS capacity is appropriate. Backup time is based on the needs of customers with configuration!
Uninterruptible power supply is the three major brands
According to the latest ranking of CCID: EMERSON, EATON, APC-MGE for the first three, but the big Iraq is about to exceed the old Ai. Fourth, five is: KELONG, DELTA
You, UPS power supply in the air off after the power can be used for how long, it controls what
Air use control system UPS is generally used to power the DCS system (the general DCS manufacturers will also have the system power supply requirements), so that the operator in the interruption of electricity, you can still operate to deal with emergencies. As for the backup time, to see Party A's requirements and budget, the design institute generally given the requirements will not be less than 30 minutes. But some design, will be in place to control the disk is also included in the UPS power supply areas, the corresponding, UPS capacity will increase. Consider the UPS model specifications, one is its backup time, the other is its allowable output current. Of course, the UPS must be an on-line UPS.
Half load is not that half of the load, full load is full load? I am a novice, I hope the old chefs do not joke.
Simple understanding, if the UPS rated output is 300W, full load refers to the UPS rated 300W, connected to the UPS above the load input power is 300W, half load is connected to your UPS above the load is 150W
