    1. Stability
    Because UPS power supply plays a role of safeguard, its own stability is more important. Therefore, the quality of the product is the first principle for users to select an uninterruptible power supply.

On the other hand, it ensures that users can have a clean power supply and protect the user's equipment.

    3. Type of UPS power supply
    It is necessary to determine the online, online interactive, standby type, sine wave, square wave and other type of UPS according to the load requirement for output stability, switching time and output wave form.

    4. Service ability
    Users’ network characteristics and electric power environment are different. Their demand for power protection also changes greatly. Users may encounter various problems when using an UPS power supply and users want to buy products and services that are fully suitable for actual needs.

    5. Accessory function
    It is recommended to adopt UPS thermal backup system in order to improve the reliability of the system, which can have series connection or parallel connection with warm backup. The uninterruptible power supply with small capacity (1 ~2KVA) can also select redundancy switch. The remote monitoring panel can be used to monitor and control the UPS work at the far end.
