The PowerWalker VFI 1000-10000 CG PF1 is a professional series for commercial applications featuring unity Power Factor (PF=1.0). The wide input voltage and frequency ranges allow operation in unstable networks and provide generator support. 1-3kVA are equipped with a very strong charger with adjustable current and 6-10kVA can present very low harmonic distortions (<1%) and high efficiency (up to 94%). Multiple accessories, including battery packs and communication cards, enhance the functionality of the UPS and allow a greater backup time. The system can be monitored locally via an LCD panel or remotely via the PowerWalker ViewPower software.
