Dura-Bilt5i MV – up to 4160 Vac, 10,000 HP

The Dura-Bilt5i MV series of medium-voltage AC-fed drives delivers simple operation in a robust and compact design, providing a cost-effective solution for a broad range of applications.  The Dura-Bilt5i MV delivers value through low cost of ownership and high reliability.

Applications
The versatile Dura-Bilt5i MV drive can be used in a wide variety of non-regenerative applications, including:
  • Fans and other high inertia variable torque loads
  • High starting torque loads such as cement kilns, extruders, and mixers
  • Conveyors
  • Pipeline and process compressors
  • Pumps of all sorts
  • Motor starting with synchronizing to the utility
The Dura-Bilt5i MV is a fully digital voltage source Pulse Width Modulated (PWM) Medium-Voltage (MV) drive with a compact and compartmentalized air-cooled design to optimize equipment segregation, cooling, and maintenance.

Power Levels & Motors The DB5i is compatible with new or existing or induction or synchronous motors from 200 to 10,000 HP, and from 2300 to 4160 volts.

Packaging
  • Only front equipment access is needed, simplifying installation.
  • Innovative but proven heat-pipe cooling in larger frame sizes provides water-cooled performance with air-cooled simplicity, from 0 to 40 C, 50 C with derating.
  • An integral incoming fused disconnect can be included without increasing the footprint.
  • A cool-operating copper-wound drive isolation transformer is included within the compact enclosure. Multiple windings provide harmonic cancellation.

Power System and Motor Friendly
The drive AC to DC converter uses a 24 pulse diode rectifier, giving power-system-friendly operation that is better than IEEE 519 harmonic guidelines.

Interfaces and Controls
  • Uses the TMEIC family common control platform, including PP7 microprocessor, control I/O, and the TMEIC Toolbox
  • The Dura-Bilt5i MV's advanced user interface, Toolbox, and system features provide fast startups, easy monitoring of operation, and close match of drive to application.

Series Designations
The Dura-Bilt5i MV product has a series designation appropriate for the outgoing motor voltage:
  • 2000 Series: 2000-2400 V ac, 200-3000 HP
  • 3000 Series: 3000-3300 V ac, 300-4000 HP
  • 4000 Series: 4000-4200 V ac, 400-7000 HP
  • A dual Frame 3 drive for 4000-4200 V ac provides up to 10,000 HP
