When the mains input is normal, UPS will be the mains power supply to the load after use, this time the UPS is an AC power regulator, while it also charge to the battery; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter switching method to the load to continue to supply 220V AC, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS equipment is usually too high voltage or voltage can provide protection.
UPS (Uninterruptible Power System), that is, uninterruptible power supply, is the battery (mostly lead-acid maintenance-free battery) connected with the host, through the host inverter and other modules to convert DC power into the main system equipment The Mainly used for a single computer, computer network systems or other power electronic equipment such as solenoid valves, pressure transmitters, etc. to provide a stable, uninterrupted power supply.
UPS and DC power supply is an important power supply protection equipment, the traditional maintenance management include: ① daily inspection appearance, regular replacement of batteries, filter capacitors, fans and other wearing parts, overhaul to do battery activation; ② transformation or use of alternative equipment , Use advanced tools to test battery performance. This kind of management way enterprise input cost is high, the maintenance personnel workload is big, it is not easy to grasp the equipment operation state and the key data in real time, the equipment accident prevention ability is low. Implementation of online maintenance management to avoid the shortcomings of the traditional way, get good benefits.
