The role of a UPS power source

---

The functions of UPS power supply can be divided into: power outage protection, voltage stabilization, surge protection, high and low voltage protection, harmonic distortion protection, stable frequency, instantaneous protection, suppress transverse and common mode noise suppression.

◪Power outage protection
In case of a sudden power failure or power failure, the UPS power supply will convert the energy stored in the UPS battery into the ac power required by the load and continue to power the load, thus avoiding the loss caused by power failure.

◪Voltage stabilization
In the transmission process, the mains voltage will be affected by some external factors, so the voltage may be high or low.The power supply of UPS can adjust and improve the supply voltage for users, which can effectively prevent the low quality and short service life of equipment caused by too high or too low voltage.

◪Surge protection
The UPS power supply system is generally designed with cutting-edge discharge, which is mainly used to absorb the surge wave, so as to prevent it from affecting the service efficiency and service life of the equipment.

◪High and low voltage protection
When the mains voltage is high or low, the voltage regulator (AVR) in the UPS power supply will control the mains voltage to a safe range for use.When the high or low voltage exceeds the available range, the UPS power supply control circuit controls the UPS battery to power the load.

◪Harmonic distortion protection
When the power is transmitted to the use end, the voltage waveform distortion occurs, and the fundamental wave current produces harmonics.The power supply of UPS can provide high quality current for the equipment, and effectively improve the operation efficiency and service life of the equipment.

◪Stable frequency
Power supply is subject to sudden changes in user's power consumption, which may cause the power frequency to be variable. At this time, the current transferred by UPS power supply can provide a stable frequency to ensure the normal operation of the equipment.

◪Instantaneous protection
Sometimes voltage surge and sag or instantaneous pressure drop will occur in mains, which will affect the precision of the equipment, and seriously damage the precision equipment and make users suffer losses.

◪Suppress transverse and common mode noise
Transverse mode noise is generated between fire line and neutral line.
Common mode noise is generated between fire line, neutral line and ground line.
