Input (three-phase)

A three-phase input is a common and powerful configuration for UPS systems, which are designed for operation with three-phase current (AC). This type of power supply is particularly used in industrial applications, large office buildings and data centers where high performance and a stable power supply are required. The three-phase input uses a voltage of 400 V and comprises three phases (P1, P2, P3), the neutral conductor (N) and the protective conductor (E).
