Power Strategy Selection Options
Tripp Lite SmartOnline LCD UPS systems offer several built-in power strategy options that enable the UPS to optimize performance to meet
user needs for MAXIMUM POWER QUALITY, MAXIMUM EFFICIENCY, and FREQUENCY REGULATION or FREQUENCY CONVERSION operation.
An additional AUTO-ADAPTIVE power strategy combines the benefits of high-efficiency and maximum power quality. Each power strategy
option enables the UPS to automatically shift between specific operating modes as power and UPS status dictates. Available power strategy
options include:
• Auto-Adaptive Power Strategy enables the UPS to automatically switch between ONLINE MODE and ECONOMY MODE as dictated by
the quality and reliability of UPS input power. If the UPS does not experience a power failure in a week’s time (not including UPS self-
test) the UPS will automatically switch to ECONOMY MODE. If a power failure occurs, the UPS will maintain output in BATTERY MODE.
When power is restored, the UPS will repeat the cycle by running in ONLINE MODE until there are no power failures for one week’s time.
Auto-bypass mode is available during UPS failure modes when AC input is within the bypass range.
• Max-Efficiency Power Strategy enables the UPS to run continuously in ECONOMY MODE anytime incoming AC power is within the
configured bypass low/high voltage range. If UPS input voltage is outside the configured bypass range, the UPS will automatically switch
to ONLINE MODE until AC input voltage is restored within the configured bypass voltage range. This is similar to Auto-Adaptive Power
Strategy, except transfer to ECONOMY MODE is immediate as voltage levels recover. There is no one-week time period of power failure
free operation required in order for the UPS to return to ECONOMY MODE operation. Auto-bypass mode is available during UPS failure
modes when AC input is within the bypass range.
• Max-Quality Power Strategy enables the UPS to run continuously in ONLINE MODE the entire time incoming AC power is within the
range for online mode operation. The UPS will remain operating continuously in Online Double-Conversion mode, providing the highest
quality output power with zero transfer time. Auto-bypass mode is available during UPS failure modes when AC input is within the bypass
range.
• Frequency Regulation Power Strategy is similar to Max-Quality Power Strategy, except the UPS will actively regulate output frequency
within +/- 0.5 Hz of the 50 or 60 Hz nominal frequency measured on startup. The UPS will remain operating continuously in Online
Double-Conversion mode, providing the highest quality output power with zero transfer time.
Note: Auto bypass during a fault is available. Bypass is not available when the UPS is in Off Mode.
• Frequency Conversion to 60 Hz & Frequency Conversion to 50 Hz Power Strategies are similar to Max-Quality power strategy,
except the UPS will actively regulate output within +/- 0.5 Hz of the 50 Hz (Freq. Conv. to 50 Hz setting) or 60 Hz (Freq. Conv. to 60 Hz
setting). Auto-bypass is not available in FREQUENCY CONVERSION mode. Typical applications include converting 50 to 60 Hz (or 60 to
50 Hz) for sensitive electronic devices.
Note: Maximum power supported in Frequency Conversion mode is derated by 30%. Auto bypass during a fault is not available.
UPS Operating Modes
Tripp Lite SmartOnline UPS systems are able to automatically switch between operating modes under conditions specified in the configured
Power Strategy. The UPS continuously indicates status using front panel LEDs and the interactive LCD viewing screen.
• Battery Mode is the UPS system’s automatic response to power failures and voltage variations outside of the online voltage range. In
BATTERY MODE, the UPS maintains sine wave AC output power from battery reserves. Once power is restored, the UPS will return to the
protected operating mode as dictated by the configured power-strategy and input power conditions.
• Online Mode (also known as ONLINE, DOUBLE CONVERSION MODE) offers the highest level of UPS equipment protection. In ONLINE
MODE, the UPS actively regenerates power from AC to DC, then from DC to AC to provide continuously regulated AC output within 2% of
the selected nominal output voltage with zero transfer time as the UPS switches between ONLINE and BATTERY modes.
• Economy Mode offers power saving operation with the highest level of UPS operating efficiency. In ECONOMY MODE, the UPS saves
energy by turning off the online, double-conversion process whenever input power is within the ECONOMY MODE voltage range. If line
voltage or frequency falls outside of the ECONOMY MODE, the UPS will respond by automatically switching to ONLINE MODE until line
voltage recovers.
• Frequency Regulation Mode gives the UPS the ability to correct frequency variations present on UPS input power. See Power Strategy
Selection Options section for details.
• Frequency Conversion to 60 Hz and Frequency Conversion to 50 Hz Modes give the UPS the ability to convert frequency from
50 Hz to 60 Hz (or 60 Hz to 50 Hz). The output frequency is fixed at 60 Hz or 50 Hz, based on the selected frequency setting. The UPS
will accept input frequency from 40-70 Hz and convert, as needed. See Power Strategy Selection Options section for details.
Note: Maximum power supported in Frequency Conversion mode is derated by 30%.
• Bypass Mode offers filtered and unregulated power to connected equipment.
