What is UPS in Parallel And Redundant Configuration?
In network, enterprise wide and industrial installations, UPS may be connected in parallel or redundant configurations: Parallel – To obtain a kVA/kW output higher than that of any single UPS. For example 2 x 200kVA modules may be connected in parallel to achieve a 400kVA output. Redundancy – To improve the overall UPS system resilience by applying the principle of N+1. Here 2 x 200kVA modules may be connected in a redundant configuration to supply up to 200kVA. Should one module fail or be taken out of service for maintenance the remaining module is sufficiently sized to power the load(s).
