PARALLEL FUNCTION
Brief Introduction
1.
N represents the minimum UPS number that the total load needs, X represents
the redundant UPS number, i.e. the fault UPS number that the system can handle
simultaneously. When the X is larger, the reliability of the power system is higher.
2. Up to 4 UPS can be connected in parallel to achieve output power sharing and power
redundancy.
