Double-conversion UPS Protect Plus S400

three-phaselithiumVRLA

Overview
Protect Plus S400 is a transformer-less online UPS offering compact footprint and flexible configurations. Using full IGBT double-conversion technology (VFI-SS-11), it delivers low input THDi and near-unity input power factor. The system supports ECO mode, reaching efficiencies > 99%. Protect Plus S400 is designed for critical applications requiring high power quality, efficient energy use, availability and limited installation/service space. It combines high battery-charging capability and a compact design to protect sensitive loads.
