The Dura-Bilt5i MV series of medium-voltage AC-fed drives delivers reliable 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.
The versatile Dura-Bilt5i MV drive can be used in a wide variety of non-regenerative applications, including:
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.
The DB5i is compatible with new or existing induction or synchronous motors from 200 to 10,000 HP, and from 2300 to 4160 volts.
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.
The Dura-Bilt5i MV product has a series designation appropriate for the outgoing motor voltage:
