Normal Mode, ECO Mode, And CVCF (Constant Voltage Constant Frequency) Mode Explanations June 07 2018, 0 Comments
Battery Backup Power, Inc. digital signal processing UPS / battery backup systems (BBP-AR series) have three operating modes. These systems are listed under "Active Backup Power" systems and have part numbers starting with BBP-AR.
1. Normal Mode (Default) - This mode keeps the inverter in a low power state and synchronized with utility (input) power so there is no delay in transferring to backup power when utility power is lost. The inverter will not take over or correct the voltage or frequency until either or both fall outside the pre-specified usable range. This mode is sufficient for most electronics and even high end computers as power is never lost when bridged between utility power and batteries. Some power, although minimal is consumed continuously to keep the inverter in its low power state.
2. ECO Mode - This mode enables the system function like a normal consumer grade UPS / battery backup. Like normal mode, the inverter will not take over or correct the voltage or frequency until either or both fall outside the pre-specified usable range. The acceptable range is wider and there is up to a 4 millisecond delay before the inverter takes over after utility power is lost. This mode is sufficient for consumer computers (won't be impacted by the short delay) and other electronics that aren't sensitive to millisecond loses of power or minor voltage/frequency fluctuations. Very little power is consumed in this mode and it is 5-7% more efficient than normal mode.
3. CVCF (Constant Voltage Constant Frequency) Mode - This mode enables the full power conditioning and real-time backup power functions of the system. No matter what the input voltage and frequency are from the utility, the output will be regulated to a steady 120 volts 60 Hz (208, 220, 230, and 240 volts are available on some models). This mode is compatible with even the most sensitive electronics like mass spectrometers, home medical equipment, and forensic analyzers. Depending on the quality of the input power, about 10% of the power consumed by the system is lost to ensure the constant output voltage and frequency are maintained.
