working principleWhen the mains input is normal, UPS stabilizes the mains and supplies it to the load. At this time, UPS is an AC voltage stabilizer, and it also charges the battery inside the machine; when the mains power is interrupted (accidental power outage), UPS immediately uses the DC power of the battery to continue to supply 220V AC power to the load through the inverter switching conversion method, so that the load maintains normal operation and protects the load software and hardware from damage. UPS equipment usually provides protection against overvoltage or undervoltage
Battery
The battery is a device used by UPS to store electrical energy. It is composed of several batteries connected in series, and its capacity determines the time it maintains discharge (power supply). Its main functions are: 1 When the mains power is normal, convert electrical energy into chemical energy and store it inside the battery. 2 When the mains power fails, convert chemical energy into electrical energy and provide it to the inverter or load.
Battery Install
The most commonly used lead-acid battery for UPS batteries is the lead-acid maintenance-free battery. The electrolyte is mainly composed of lead and sulfuric acid. It does not require water or acid to be added during use, has good sealing performance, and is cost-effective as a UPS battery.
