Data Device Corp. High-efficiency three-phase motor drive

This high-power three-phase bridge drive is designed to deliver current to windings of three-phase brush and brushless dc motors. The PWR-82335 motor drive offers up to an 8X improvement in power efficiency compared with the previous-generation PWR-82331 bridge drive and is a pin-compatible direct replacement. The compact motor drive hybrid uses a high-efficiency MOSFET drive stage with a 200-Vdc rating to deliver a high-speed switching frequency of up to 50kHz and a high current capability of up to 30 A to the motor. The motor drive features an extended -55 to 125 °C temperature range and can endure shock and vibration.
