1. UPS power Usually, the power value of UPS is represented by VA. When selecting UPS power supply, first calculate the VA value of medical equipment and leave a certain margin to determine the power of UPS power supply.
2. The types of UPS output waveforms are usually divided into square wave backup type, sine wave online interactive type and online type. Sine waves are characterized by no harmonics, zero second transitions. Medical equipment is a high-precision instrument and has very high requirements on the quality of the power supply. In actual use, an online UPS power supply is usually selected, which can well avoid power supply interference.
3. Selection of battery capacity The capacity of the backup battery can be divided into two types: the standard machine and the extension machine. The standard machine has a built-in battery, which can generally extend the use time of the equipment for 10 to 15 minutes after a power failure, while the extension machine is generally equipped with a battery cabinet. It can usually be extended for a longer period of time. In practical applications, it is usually selected according to needs.
