ZK SK Series UL 1283 440VAC Three Phase EMC Line Filter 5A-1200A for Solar VFD and Inverters
Professional sine wave output filter designed for solar VFD and variable frequency inverter applications with UL 1283 certification and 440VAC rating.
The ZK SK Series is a high-performance three-phase EMC filter composed of capacitance, inductance, and resistance circuits. This advanced filter effectively eliminates specific frequency interference in power lines while maintaining clean power signals for optimal motor performance.
Specifically engineered for installation at the output end of frequency inverters and servo drives to:
- Solve interference issues between frequency inverters and motors
- Reduce motor noise and prevent rapid motor aging
- Protect motors from harmonic distortion and voltage spikes
- Reduces EMC interference on motors from VVVF or servo output side
- Prevents harmonic interference from inverters affecting motor performance
- Suppresses DV/DT and relieves peak voltage harm from inverters on motors
- Reduces RFI interference from long cable runs on frequency inverter output side
- Provides over-voltage protection and reduces 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
