1, UPS uninterruptible power supply does not require manual operation can be automatically switched to the power supply mode, in the case of power and no power to go to a different path, which is conducive to the reduction of energy waste. Reduce energy waste.
2, UPS power supply system in the power grid blackout only began to run, so it will not interfere with the normal grid power supply, very safe.
3, in the installation, only need to connect the backup power supply into the circuit, it has a specific port to connect, can be for different equipment, connected to different interfaces.
4, UPS uninterruptible power supply will not take up too much space, it is easy to find the installation location. When the equipment running space is small, you can choose a similar computer mainframe size products.
5, UPS uninterruptible power supply main advantage lies mainly in the uninterruptible power supply capacity, when the utility power is normal, UPS AC rectified into DC, and then DC reverse into a stable and unadulterated AC power supply to the load. Conversely, the DC can be reversed into a stable and unadulterated AC power, and continue to give the load use.
Disadvantages of UPS
1, when the electrical equipment on the power supply interval time requirements of harsh, it is not suitable for the use of uninterruptible backup power. This is because the UPS power supply method has a longer response time, so the more sensitive equipment for charging and discharging can not use this type of power.
2, UPS uninterruptible power supply input range is narrow, the output power supply quality is poor, and thus the comprehensive availability of poor. If the power of the equipment is large, the need for more power, the use of standby power is also inappropriate.
Uninterruptible power supply can power how long
UPS uninterruptible power supply time is not unlimited, this time is subject to the size of the battery's own stored energy, the size of the load, the ambient temperature, the battery discharge cut-off voltage and other factors. In general, small home computer UPS uninterruptible power supply time can be maintained for about 20 minutes, large kilowatt level UPS can be set up according to the requirements of the battery pack, power supply time up to more than 1 hour, and some can even power 10 hours.
UPS uninterruptible power supply in the end can be used for how long, to be combined with the actual situation to calculate. Normally, UPS manufacturers will adjust the power and emergency time on the basis of consumer requirements, so as to ensure that the load can start safely and smoothly, while the backup time is more guaranteed. If an AC blackout occurs, then the UPS battery power supply in the valuable time, the user needs to do is to hurry to restore the AC power, such as enabling the backup AC power circuit, enabling the oil generator to generate power, can not be done, it can only be an emergency depository, save the fruits of labor, waiting for the AC power to return to normal and then continue.
