A True Online UPS provides the ultimate power protection with clean and stable electrical power for critical target loads. Using the Double Conversion topology the Online UPS isolates equipment from the commercial input power source. This process stabilizes line voltage conditions, frequency regulation and provides uninterruptible power during a power failure event.
Double Conversion Process
- Incoming AC power from a commercial power source or onsite power generation, is fed to the Online UPS’ internal rectifier. The rectifier converts the electrical power from AC to DC power and voltage is regulated.
- The DC power charges the UPS’s backup battery and feeds power to the inverter for conversion back to AC power.
- The resulting “double converted” electrical power is pure sine wave output providing near perfect output power to the load.
- In the event of total power loss, the UPS’ internal backup batteries will continue to supply power to the DC AC inverter. There is no transfer time as the transition to battery backup power is instantaneous.
