    Tips: How to prolong the power-on time of UPS power supply?

    There are two ways to prolong the power-on time of UPS system.

    1. External connection of high-capacity battery group to UPS

    The corresponding capacity battery backup shall be connected according to the power-on time required. But it should be noted that this kind of method will increase the charging period of the battery pack, floor area and maintenance cost.

    2. Choose high-capacity UPS system

    This method can not only reduce the cost of maintenance. If the load equipment is expanded, the high capacity UPS system can still operate immediately.
