First, what is UPS uninterruptible power supply
UPS is an uninterruptible power supply. In the past, batteries (mostly lead-acid maintenance-free batteries) were used the most. Lifepo4 battery, compared with the original lead-acid battery, the volume and weight of this battery are reduced by two-thirds, and the service life is 5 times that of the lead-acid battery. The most important thing is environmental protection, and it has also been favored by consumers. The battery is connected to the host, and is a system device that converts direct current into commercial power through the host inverter and other module circuits. It is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine; when the mains is interrupted (accidental power failure) When the UPS is turned on, the UPS will immediately supply 220V AC power to the load through the method of inverter zero-switching conversion, so that the load can maintain normal operation and protect the software and hardware of the load from damage. UPS equipment usually provides protection against overvoltage or undervoltage.
Second, how to choose UPS uninterruptible power supply
First, choose UPS uninterruptible power supply according to the purpose. It is necessary to measure the power of electrical equipment and the power of UPS uninterruptible power supply to see if it can meet the needs of your work and life.
Second, choose a brand of UPS uninterruptible power supply. UPS uninterruptible power supply is a very important power failure emergency equipment. If the product quality is not good and the after-sales maintenance is not good, it is easy to cause a lot of trouble.
Three, according to the working environment to choose UPS uninterruptible power supply. According to the use environment, it can be divided into industrial-grade UPS and commercial-grade UPS. Industrial-grade UPS is suitable for places with relatively harsh environments, and commercial-grade UPS has relatively high requirements on the environment.
