The NS LCD PF1 series, featuring true Online Double Conversion (VFI) technology, ensures a continuous, stable, and regulated pure sine-wave AC supply for mission-critical applications. With a unitary Power Factor (PF 1), the active power (W) fully matches the apparent power (VA), delivering superior performance and energy efficiency for demanding industrial and IT infrastructures.
SINGLE PHASE ONLINE DOUBLE CONVERSION SINEWAVE UPS 1000VA – 3000VA, NS LCD SERIES
Description
Normal Mode: Under standard utility conditions, the load is directly fed via the Inverter, while the Rectifier maintains battery charge and supplies the
necessary power to the output stage.
Battery Mode: Should a blackout, phase loss, or voltage fluctuation occur, the battery powers the Inverter with zero transfer time, ensuring uninterrupted operation for critical equipment.
Automatic Bypass: In the event of an overload, internal fault, or overtemperature, the load is instantly transferred to the emergency line (Static Bypass) and automatically reverts to the Inverter once nominal conditions are restored .
