DNH Industries offers a complete line of solid state motor starters from 30 HP to 6750 HP in low and medium voltage configurations.

Designed for efficiency and the handling of heavy load switching, these motor controllers meet the demands of the most critical  applications.

Digi-Fire motor starters replace wye-delta, auto-transformer and resistor or reactor starters. They provide smooth stepless acceleration and deceleration with no sudden power surges caused by contactors stepping up the voltage to the motor. You get a more reliable controller that puts much less stress on the motor and this will result in economic savings through reductions in system repairs and motor replacements.
