The ZK SK Series sine wave filter is engineered for use in low-voltage filter cabinets, where it connects in series with filter capacitors to create resonant circuits that effectively absorb harmonic currents from power grids. This solution is essential for systems containing harmonic sources like rectifiers, converters, and frequency converters, which can compromise the safety of main transformers and other electrical equipment.

• Excellent interference suppression for dv/dt applications
• Over-voltage protection to reduce electromagnetic interference
• Wide operating current range from 5A to 1200A
• High-quality components ensure safety and reliability
• Reduces inverter and motor choke losses
• Multiple connection options: bolt and busbar terminals

Ideal for solar pump inverters, variable frequency drives (VFDs), and frequency inverters in industrial and renewable energy systems. Effectively improves system power factor while ensuring safe operation of electrical equipment.
