Tips: Types of UPS

  • Passive backup ups power supply. It refers to the inverter connected in parallel between the mains and the load is simply used as a backup power source. This kind of UPS power supply, when the mains is normal, the load is completely and directly municipal power supply, the inverter does not do any power conversion, the battery is powered by an independent charger. When the mains is abnormal, the load is completely supplied by the inverter.
  • Online interactive ups power supply. It refers to the inverter connected in parallel between the mains and the load, play the role of backup power supply, while the inverter as a charger to charge the battery. The reversible operation of the inverter interacts with the mains, so it is called interactive. This kind of ups power supply, when the mains is normal, the load by the improved mains power supply, and the inverter as a charger to charge the battery, at this time the inverter plays the role of AC/DC converter; When the mains fails, the load is completely powered by the inverter. At this time, the inverter acts as a DC/AC converter. The online interactive ups has the advantages of simple structure, convenient implementation, easy parallel connection, easy maintenance and repair, high efficiency, low operating cost, and high reliability of the whole machine. The performance meets some load requirements, especially suitable for the distributed power supply system of some computer equipment in the network.
  • Double transform ups power supply. Double transform ups is the main product of ups power supply. It has the advantages of good performance, high voltage stability and frequency stability, strong function, hot backup connection and parallel redundancy connection. Its deficiency is that when the capacity is less than 10kVA below, the efficiency of the whole machine is not high, generally about 85%.

Perfect combination of pure sine wave and ups
I am most satisfied that this 3500W inverter is a ups inverter. Perfect combination of pure sine wave and ups. I use the 3500W pure sine wave ups inverter about twice a month. So far, there have been no problems with the inverter.
