DC/DC Crane Controls - Type 4970

DC-to-DC Controller


  • IGBT based DC PVM Inverter designed to operate from 200 to 600 V bus supplies.

  • Reduced brake wear-break sets near zero speed.

  • Smooth DC output current reduces motor commutator wear.

  • Uses existing classic 4 conductor control for ease in retrofitting existing contactor control applications.

  • Full motor torque produced from stall to base speed, plus light load ultra speed capability.

  • Retains classic power limit switch functionality and DB contactor resistor circuitry providing traditional dynamic lowering safety features.

  • Speed control is 3-5 speed, infinitely variable and the analog voltage or current setups are standard.

  • Radio control or serial communications to a PLC can be added anytime.

  • Four quadrant regenerative drive.

  • 55 degrees C ambient rating.
