On-line UPS Master HP FC UL

three-phaseindustrialdata center

Three-phase voltage and frequency conversion for testing or operation of systems with European standards HIGHLIGHTS • High efficiency • IGBT-based rectifier technology • Output voltage:400 V - 50Hz • Galvanic isolation • High overload capacity The high levels of quality, reliability and energy savings offered by the Master HP range of UPS have been extended to include frequency converter 480 V - 60 Hz input /400 V - 50 Hz output certified as UL, with power ratings from 80 to 200 KVA. The typical application of such Frequency Converters is the power supply of the loads at 400 V , 50 Hz as for example imported from other countries. The FC units can work with or without battery. With its double conversion on-line technology based entirely on IGBT and digital signal processors (DSP), the Master HP FC UL range ensures maximum critical load protection, with VFI SS 111 classification (Voltage and Frequency Independent) in accordance with IEC EN 62040-3. This range is designed using a new configuration that includes an IGBT sinusoidal input rectifier. Unique in its design, double conversion technology with galvanic isolated output guarantees a quality power supply that is completely protected from all electrical anomalies at the input.
