Issue:
What is "Green Mode" on a Smart-UPS, Smart-UPS On-Line, Smart-UPS Ultra?

Product Line:
Smart-UPS (SMC, SMT, SMX, SMTL), Smart-UPS On-Line (SRT), Smart-UPS Ultra (SRTL)

Environment:
All models, all serial numbers

Resolution:

Green Mode utilizes relays that bypass certain internal components of the UPS during normal steady-state operation. This feeds power directly from the utility, enabling higher UPS efficiencies, greater than 97% for certain models.
Not only does this save on power utility costs but also on the cooling required in tight spaces as the unit emits less heat losses. The lower heat also leads to longer life of key components such as batteries.
If the quality of the power drops outside of configurable ranges, the UPS will immediately switch into On-Line, or On-Battery mode, and the switchover can take up to 10 ms.
Note that the UPS output will be subject to variations in input voltage or frequency within the configurable ranges while the UPS operates in Green Mode. Customers must determine if these potential variations are acceptable to the load connected to the UPS.
