UPS uninterruptible power supply how to work a few instructions

UPS uninterruptible power supply has become the current data center of the important equipment, understanding UPS work Mode UPS is a basis for daily maintenance. The following according to the different electrical environment, said UPS uninterruptible Power supply Work mode problem.

First, the normal operation of the mode of work
Under normal circumstances, UPS uninterruptible power supply system principle is when the mains electricity normal when the AC input power conversion to direct current, and then charge the battery, in case of power interruption use; it should be emphasized that the uninterruptible power supply system is not a power outage will work, such as encountering voltage is too low or too high, instantaneous surge, etc. When the power quality is sufficient to affect the normal operation of the equipment, the UPS system is in working condition, providing a stable and clean power supply for the load equipment.

Ii. working mode of bypass operation
When the mains power is normal, when the UPS is overloaded, the Bypass command (manual or automatic), the inverter is overheated or the machine is faulty, UPS usually turns the inverter output to the bypass output, which is the direct power supply from the mains. Due to the bypass, the UPS output frequency phase needs to be the same as the mains frequency phase, so the use of lock-phase synchronization technology to ensure that UPS power output and mains synchronization. Bypass switch bidirectional SCR parallel operation mode, solve the bypass switching time problem, really do 0 time switching, control circuit complex, generally used in high-power ups power supply. If the device is overloaded, the load must be artificially reduced or the bypass breaker will automatically cut off the output.

Third, the mode of operation of the backup battery
Once the mains is abnormal, the UPS will convert the DC power stored in the battery into alternating current, the inverter input is changed by the battery pack to supply, the inverter continues to provide power, the supply load continues to use, to achieve continuous power supply function. As the capacity of the battery is limited, so UPS power supply will not be like the mains power supply continuously, so no matter how much capacity of the UPS system, in its full load state, its power supply time is bound to be limited, to extend the discharge time, must buy long-delay UPS power supply.

Iv. working mode of Bypass maintenance
When the UPS emergency power supply for maintenance, by manually setting the bypass to ensure the normal power supply of the load equipment, when the repair operation is completed, restart the UPS power, the UPS power to normal operation at this time.

The above four aspects are in fact from the mains normal and mains abnormal or normal maintenance time to explain ups uninterruptible power work mode , it is because ups work mode of the unique, super power, so it has an irreplaceable role in the application of electricity.
