The 590P Series DC Drive is designed for use in a suitable enclosure, with associated control equipment. The unit accepts standard
three-phase ac supply voltages in the range 110V to 660V, depending upon the model, and is suitable for the powering of DC shunt
field and permanent magnet motors, providing controlled dc output voltage and current for armature and field.

The coding circuitry adjusts automatically to accept supply frequencies between 45-65Hz and possesses high immunity to
supply-borne interference. The armature controllers are phase rotation insensitive.
