How to enable "Green Mode" on smart-ups SMT750

[BillP]

Hello,

Where can I enable the Green Mode in the LCD menus of the SMT750? How can I know if the UPS is running in this mode?

Thank you !

Hi,

The UPS will run in Green Mode automatically when the power quality is good. The information below is from Knowledge Base document FA156594

How does the ‘green’ operating mode increase efficiency?

APC’s patent pending ‘green’ mode bypass components that perform automatic voltage regulation (AVR) when not needed. AVR is typically handled in the line interactive design by solid state transformers. These transformers, while extremely reliable, do have some energy loss to remain energized. By using these transformers only when needed results in higher efficiencies across a wide range of load conditions.

Do I sacrifice any protection by operating in ‘green’ mode?

Absolutely no power protection is sacrificed in ‘green’ mode. In this mode the UPS is providing surge and noise filtering and can react to any change in power that requires voltage regulation or inverter operation in a matter of milliseconds.

What is the typical energy savings with ‘green’ mode?

When compared to APC’s very efficient existing line interactive models, the increase in efficiency ranges from 1-4%. For an average 1500VA UPS this may save $25-30 per year in utility costs.

To verify the unit is in green mode press the escape key and then select status.
