Liebert Trinergy – Circular Redundancy  Optimum energy management

when operating with partial loads provides energy cost savings in any installation where frequent variations of load occur  Here’s how it works

– Special logic detects the number

of modules needed to supply the load while maintaining the redundancy The modules not needed work in a special standby mode that ensures the reliability of the system A special algorithm checks that each module operates in standby mode for the same amount of time

• Same ageing of modules
