DU/DT Filter
The Shakti DU/DT Filter is an output line filter designed for connection between variable frequency solar drives and electric pump motors. It limits the voltage rate of rise (dV/dt) and suppresses high-frequency voltage spikes generated by fast-switching inverter electronics, protecting motor winding insulation during long cable installations.
Overview and Features
General Data
Features:
- Reduces dV/dt voltage rise rates and terminal voltage peaks to protect motor insulation.
- Minimizes motor acoustic noise and operational temperature rise.
- Extends permitted cable lengths between drive and motor up to 500 meters.
- Supports motor currents up to 14 Amperes.
- Robust IP 54 metal enclosure for dust and splash protection in rural and industrial installations.
Applications:
- Submersible and surface solar pump installations with long borehole cable runs up to 500 meters.
- Industrial VFD installations requiring motor winding surge protection.
- Deep well solar water pumping systems.
