Global uninterruptible power supply (UPS) development status in 2018UPS products first appeared in the late 1960s and have been developed for 40 years so far. UPS products were applied to the industrial market in the early days. They are automated industrial system equipment, remote execution system equipment, high-voltage circuit breaker switching, and relay protection. , Automatic devices, signal devices and other equipment and devices of AC and DC uninterruptible power supply equipment. As a

At present, there are many brands of UPS uninterruptible power supplies in the market , the product quality is uneven, and the competition is chaotic. How to choose suitable UPS products, end users need to improve their understanding of UPS uninterruptible power supplies. Experts said that when choosing UPS uninterruptible power supplies, we can start with four major standards and choose products that meet their requirements to truly ensure uninterrupted operation of daily business.One of the st

I. Safety Instructions1. Even if the UPS is not connected to the mains, its power output socket still has a voltage of 220V.2. In order to reduce the risk of electric shock caused by poor grounding of the load equipment, when installing the computer interface signal cable, the AC input power should be disconnected, and the power can only be connected after all signal connectors are connected.3. Connect the UPS to the AC input power supply with a ground wire. It must be equipped with a proper bra

According to the working principle of UPS uninterruptible power supply , there are backup UPS , online UPS and online interactive UPS.Back-up UPS uninterruptible power supply. The English is Back UPS or Off-line UPS. The UPS battery is in the main machine, which is also called standard machine / standard machine. Because the battery is in the UPS main unit, the backup UPS uninterruptible power supply has a shorter load time, usually a few minutes. When the mains power fails, it usually takes a f

Foreword:The UPS system is usually used in the computer room of the intelligent system . So what exactly does the UPS system mean and how to choose it?text:First, the meaning of UPS uninterruptible power supplyMeaning: UPS is an uninterruptible power supply. It is a system device that connects the battery to the host and converts DC power to mains power through module circuits such as the host inverter. It is mainly used to provide a single computer, computer network system or other power electr

1) Voltage stability --- The mains voltage is easily affected by the quality of the power transmission line. The user voltage near the substation is higher by about 130 ~ 120V, and the user voltage farther from the substation is lower by about 100 ~ 90V. If the voltage is too high or too low, the life of the user equipment will be shortened, and the equipment will be burned in severe cases. The use of online UPS can provide a stable voltage power supply, and the voltage change is less than 2V, w
