5. Operation
Frequency Conversion
The UPS system automatically selects 50 Hz or 60 Hz operation based on utility power conditions
at start-up and regulates output power within ± 0.05 Hz of the selected frequency. The UPS system
also has an advanced setting that allows continuous frequency conversion from 50 Hz to 60 Hz or
from 60 Hz to 50 Hz. The advanced frequency conversion setting is accessible through PowerAlert
software or the optional WEBCARDLX internal accessory card. When continuous frequency
conversion is enabled, the maximum output capacity of the UPS system is derated by 30%.
5.3 Power Strategy Selection Options
Tripp Lite SmartOnline 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. The default
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 (Default from factory)
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.
Max Efficiency Power Strategy
Enables the UPS to run continuously in ECONOMY MODE any time 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.
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
Similar to Max Quality Power Strategy, except the UPS will actively regulate output frequency within
+/-0.05Hz of the 50 or 60Hz 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. Auto-bypass mode is available during UPS failure modes when AC
input is within the bypass range.
Frequency Conversion to 60Hz & Frequency Conversion to 50Hz Power Strategies
Similar to Max Quality power strategy, except the UPS will actively regulate output within +/-0.05Hz
of the 50Hz (Freq. Conv. to 50Hz setting) or 60Hz (Freq. Conv. to 60Hz setting). Auto-bypass is not
available in FREQUENCY CONVERSION mode. Typical applications include converting 50 to 60Hz
(or 60 to 50Hz) for sensitive electronic devices.
Note: Maximum power supported in Frequency Regulation/Conversion modes is derated by 30%.
