Energy saving for fan and pump applications


Dedicated functions for fan and pump.

Bumpless transfer: switches operation smoothly between Local Mode and Remote Mode.

Fire control mode: forcibly makes the motor keep operating at the preset speed in an emergency condition.

Sleep mode: automatically stops operating at lower operating condition than the minimum limit.

Improvement of energy saving effects.

The VF-PS1 has the advanced energy-saving mode, which maximizes efficiency of the motors and increases fan and pump efficiency even at low speed. *The efficiency of induction motors is normally down at low speed.

Simple set-up with Easy Key.

The Easy Key provides quick access to up to 32 frequently-used parameters (Easy Mode).

High frequency noise reduction, harmonic reduction.

The built-in EMC filters and DC reactors reduct drastically high-frequency noise and harmonics, and improve power factor.
