SAPF series harmonic filtering electric device
Description
SAPF series active harmonic filter is applicable for places requiring dynamic reactive compensation or harmonic control, especially suitable for occasions with mill, spot welder, crane, elevator and traffic.
Standard Adopted
• GB/T14549-93 • GB7251.1-2005
Performance Highlight
• Wide harmonic filtering range: 2nd~50th harmonic can be filtered
• High efficiency: harmonic filtering rate: more than 95%
• Quick response: Fast dynamic response speed. Response time is below 10 ms
• Free from resonance due to automatic resonance elimination
• Free from overload due to automatic current-limit output
• Concurrent Var compensation: Filtering and Var compensation available for choice
• Complete protection includes over voltage, under voltage, over current, over heat, under voltage of control supply and so on.
