JNTECH dV/dt Filter for 11kW–18.5kW Solar Pump Inverters/VFDs

JNTECH dV/dt Filter for 11kW–18.5kW Solar Pump Inverters/VFDs

The JNTECH dV/dt Filter for 11kW–18.5kW Solar Pump Inverters/VFDs is designed to provide additional protection for three-phase water pump motors, especially in installations with a long cable distance between the solar pump inverter and the motor.

Installed on the output side of the JNTECH solar pump inverter/VFD, the dV/dt filter helps reduce rapid voltage rise (dV/dt), high-frequency voltage spikes and electrical stress caused by PWM inverter output. This helps protect motor winding insulation and submersible pump motors in demanding solar pumping applications.
