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.
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
UPS (uninterruptible power supply) how to calculate the power supply, such as 100W electrical power can be how long?
UPS power supply capacity is mainly from its own capacity and the size of the load to consider. UPS is actually a power supply, put its power (of course, in the case of full) / load power = use time
What is the uninterruptible power supply
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 equipment is usually too high voltage or voltage can provide protection.
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!
Ups uninterruptible power supply back - up and on - line difference is what does anyone know?
Backup UPS is also known as non-online UPS ??Backup UPS: usually in the battery charge state, in the event of an emergency switch to the working state of the inverter, the battery provided by the DC into a stable AC output, so the backup UPS is also known as off-line UPS. Backup UPS power supply advantages are: high efficiency, low noise, the price is relatively cheap, mainly applicable to major fluctuations in electricity, the power supply quality requirements are not high occasions, more suitable for home use. However, this UPS has a switching time problem and is therefore not suitable for use where critical power supplies can not be interrupted. But in fact this switch is very short, usually between 2 to 10 milliseconds, and the computer's own switching power supply in the power failure should be able to maintain about 10 milliseconds, so the personal computer system is generally not because of this switching time problem. Backup UPS can only continue to power a few minutes to tens of minutes, mainly to let you have time to back up data, and as soon as possible the end of the work, the price is low. For computer applications that are not too critical, such as personal home users, they can be equipped with a low-power backup UPS.
General household ups, can not external socket?
Can, but note the following: 1, the external socket electrical appliances and UPS original electrical total power can not exceed 70% of ups capacity. 2, do not plug the motor a kind of inductive load, such as impact hammer, hair dryer, vacuum cleaner and so on. 3, the external socket itself is better quality, the choice of regular manufacturers of products. 4, to prevent dust, water into the socket caused by short circuit or leakage. 5, for a long time do not, should pull out the external socket, to prevent others misuse.
Ups power delay can be how long
if the longer delay is not impossible, you may need to add other charger.
Ups is what kind of equipment
UPS is the "uninterruptible power supply", is the English "Uninterruptible Power Supply" abbreviation, it can protect the computer system after the power failure to continue working for some time so that users can save the emergency, so that you will not cause work or loss due to power outages data. It is in the computer system and network applications, mainly play two roles: First, emergency use, to prevent sudden power failure and affect the normal work, to the computer damage; the second is to eliminate electricity surges, instant high voltage, instant Low voltage, wire noise and frequency offset "power pollution" to improve the quality of power for the computer system to provide high-quality power supply. From the basic application principle, UPS is a kind of energy storage device, inverter as the main component, stable power frequency output power protection equipment. Mainly by the rectifier, battery, inverter and static switch and other components.
