The UPSs that are designed with parallel architecture can operate redundantly and provide power to the loads in various ways.

1. Parallel-Capacity (N) where the total power requirement is covered by N identical UPSs paralleled to each other.

2. Parallel-Redundant (N + X). This architecture of parallel connection offers increased reliability and protection in many critical applications. The UPSs that support this architecture are connected in parallel and share the total power of the application with this mode ensuring that in case of failure of one UPS, the remaining ones can seamlessly provide the required power.

The Prime Plus of Tescom Hellas is a UPS paradigm that supports parallel operation.
