PowerWalker VFD APFC series is a standby/offline UPS for home and office applications and it is equipped with a technique that allows using the full power of UPS, even when used with APFC power supply load. Usually it is required to oversize a UPS to ensure secure backup when connecting a power supply with active power factor correction. With the implemented technology this is no longer needed. Therefore you can choose smaller cost-effective UPS (e.g. PowerWalker VFD APFC instead of usual offline or line interactive 1000 VA model). Besides the lower purchase price, it also saves energy cost due to lower own power consumption.Equipped with 6 Schuko-Type outlets (all with surge protection, 4 with battery backup) these models can be used like a power strip. A special battery compartment enables an easy exchange of the rechargeable battery by the user.
