·The Basic Functions of UPS
1. When grid voltage is normal, electricity supply is supply to the use of load after the voltage regulator of the UPS. UPS with good performance itself is a good communication regulator. At the same time, it can charge the battery inside the machine to store back-up energy;
2. When grid voltage is abnormal (undervoltage, overvoltage, power-down, interference, etc.) UPS inverter to the DC battery pack can be converted into AC power to maintain the load power supply;
3. UPS can have automatic conversion between the battery-powered electricity and grid-powered electricity, to ensure uninterrupted power supply to the load. General computer equipment can allow a very small power interruption (switching time less than 10ms), but the sophisticated computer equipment and communications equipment does not allow any interruption of electricity (switching time of 0ms), so you need to be sure the exactly switching time of the UPS.
