Introduction

Nord NORDAC PRO SK550P  AC Variable Speed Drive (VSD / VFD) for 0.25 kW 230V three-phase motors. Converts a fixed frequency 200-240 Vac single-phase supply to a 200-240 Vac three-phase variable frequency output to control the speed of a standard AC induction motor or permanent magnet synchronous motor.

The Nord SK530P is a well featured industrial inverter drive for a wide range of industrial applications including continuous process lines for the plastics and paper industries.
