Protect Plus S500 250 - 600 kVA transformer-less UPS with 3-level IGBT technology

1/2

Protect Plus S500 is a monolithic transformer-less UPS that combines high AC/AC efficiency with compact footprint and flexible configurations. Its high level of performance, wide range of options and minimized operating costs, makes it the perfect solution to backup any business-critical load. Thanks to its full IGBT double conversion technology (VFI SS 111), Protect Plus S500 combines low input THDi with almost unity input power factor.

Smart Eco Mode

  • Increases efficiency by supplying the load trough the bypass line
  • The bypass input line is always monitored
  • The Inverter is synchronized with bypass
  • If a poor quality of the AC line is detected, the inverter will operate as harmonic compensation and power factor correction, while the bypass line is still connected to the load
  • Switching time < 4 ms

Intelligence Test Mode

The UPS will be capable to perform the Intelligent Test Mode (function for quick commissioning): a function that will run both in single input (rectifier and static bypass connected together) and dual input connections (rectifier input line and static bypass input line separated). When set in Intelligent Test Mode the UPS will use its own nominal current (that flows in loop through the UPS) to carry a self-test at full load, without using external dummy loads connected to the UPS. The energy consumption in Intelligent Test Mode equals to the energy consumed by the UPS itself.
