MVF20 Series

Features & Benefits

• System voltage: 3.3–11 kV ±10%
• Motor shaft power range: 250–10,900 kW
• Requires no rear or side entry to perform repairs or maintenance, making it suitable for installation against walls
• Motor cable entry is possible from the top or bottom

Specification

• Control power: Single-phase 220 VAC; 5 kVA
• System efficiency: >98.5% (at rated; excluding transformer)
• Power factor: >0.96 (at rated)
• Input current/output voltage harmonics: <5% (at rated), meeting IEEE519-1992 and GB/T 14549-93 standards
• IGBT-based cascaded connection is used to achieve different working voltages; the waveform of multi-level output voltage approximates a sine wave
