How to choose UPS uninterruptible power supply for CMM

First of all, determine the power of the equipment, generally speaking, the power of the ordinary PC or industry is about 200w, the MAC is 300w, the server is between 300w and 600w, and the power value of other equipment can refer to the instruction manual of the equipment.

The power factor of the backup, online interactive is between 0.5 and 0.7, and the power factor of the online type is generally 0.8. To match the UPS with the device, use the actual output power of the UPS as the basis.

According to the choice of use environment can be divided into industrial UPS and commercial UPS. Industrial UPS ADAPTS to harsh environments, and commercial UPS has higher requirements for the environment.

UPS is usually divided into power frequency and high frequency two. The power frequency UPS is composed of thyristor rectifier, IGBT inverter, bypass and power frequency boost isolation transformer. The frequency of the rectifier and transformer is 50Hz.

A high frequency UPS usually consists of an IGBT high frequency rectifier, a battery converter, an inverter and a bypass. The switching frequency of IGBT rectifiers is usually in a few K to tens of KHz, or even up to hundreds of KHz, compared with the 50 hz power frequency, which is called high frequency UPS.

With the development of power electronic technology and high frequency power devices. UPS products in the small and medium power segment have gradually developed to high-frequency and high-frequency UPS, which are characterized by large power density, small size and light weight. However, in the process of high-frequency UPS power supply, there is a transition of dual power supplies. High-frequency topology UPS exposes some inherent shortcomings during use, which affects the safe use and operation of UPS.
