The Enertronic S is a true on-line tower configuration UPS, consisting of up to eight parallelable power boards within a single unit. Each power board offers an output of 1.25kVA for a maximum total system output of 10kVA (single phase). Manual bypass, extended battery autonomies, RS232 and volt-free communications options complete the specification. 

Key features include:

• Input power factor >0,99
• THDI <3%
• Static and manual bypass
• Class A/B (immunity/emission)
• Extended battery autonomy
• Input frequency auto sense
• Noise level <40dBA
• Long life battery control
• RS232 and volt-free contact

The Enertronic S is of modular construction, with each power board comprising its own inbuilt rectifier, inverter, controller and static bypass switch effectively eliminating any single points of failure. The modular design of the Enertronic S also enables a very low ‘Mean Time to Repair’ (MTTR) thereby boosting system, and hence load power, availability. 

The Enertronic S can also be operated in a parallel redundant N+1 configuration by fitting one more power board (+1) than the critical load (N) requires. In such a configuration, in the event of a power board problem the UPS will continue to operate in true on-line mode until the problem power board is replaced. Furthermore, the power board can be quickly replaced without disruption to the critical load.
