Submersible pumps
Submersible pumps of various powers can be powered by MIDA. It is suggested to set to 2.5 kHz the carrier frequency (PWM parameter) and sometimes it is necessary to install a filter between pump and inverter to:
- reduce the spikes on the motor windings caused by voltage reflection (dv/dt filters)
- avoid electromagnetic noise in the surrounding environment (sinusoidal filters).
It is recommended to keep separate the motor cable from other cables granting a certain distance. Nastec can provide filters and shielded cables for a proper pump installation.
