500w Pure Sine Wave UPS Low Frequency Solar Inverter Single Phase Automatic Door

500w Pure Sine Wave UPS Low Frequency Solar Inverter Single Phase Automatic Door

Passive backup UPS power supply:

The inverter is connected in parallel between the mains and the load and is simply used as a backup power source. This UPS power supply, when the mains is normal, the load is completely and directly local power supply, the inverter does not do any power conversion, the battery is powered by an independent charger; When the mains is not normal, the load is completely supplied by the inverter.

Passive backup UPS has the advantages of simple structure and cheapest price. It is used for some non-essential load use, such as home computers. However, when the mains power is off, the relay will switch the inverter to the load. The switching time is relatively long, which generally takes a few milliseconds to interrupt, so the passive backup UPS power supply should not be used for slightly important computer equipment.

Online interactive UPS power supply:

Refers to the inverter connected in parallel between the mains and the load, plays the role of backup power supply, while the inverter as a charger to charge the battery. Through the reversible operation of the inverter, it interacts with the mains, so it is called interactive. This UPS power supply, when the mains is normal, the load is powered by the improved mains, and the inverter is used as the charger to charge the battery. At this time, the inverter plays the role of AC/DC converter; And when the mains failure, the load is completely powered by the inverter, at this time, the inverter plays the role of DC/AC converter.

The on-line interactive UPS has the advantages of simple structure, convenient implementation, easy parallel connection, easy maintenance and repair, high efficiency, low operating cost, high reliability of the whole machine, and the performance can meet some load requirements, especially suitable for some computer equipment in the network using distributed power supply system. The disadvantage of this kind of power supply is low voltage performance, especially low dynamic response speed, second anti-interference ability is not strong, the circuit will produce harmonic interference and modulation interference.
