30A/200V High-Efficiency Smart Power 3-Phase Motor Drive

New Products | August 17, 2017

Data Device Corporation (DDC) introduces a new high power 3-Phase Bridge drive designed to precisely deliver current to windings of 3-Phase Brush and Brushless DC Motors, with a high-efficiency MOSFET drive stage. 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 rugged, compact 3-phase motor drive hybrid (PWR-82335) utilizes a high-efficiency MOSFET drive stage with 200 VDC rating, to deliver a high-speed switching frequency of up to 50kHz and a high current capability of up to 30A to the motor. Featuring an extended -55°C to +125°C temperature range, with available military processing options, the PWR-82335 is ideal for harsh, space constrained defense and aerospace environments.

Benefits:

Ideal for harsh defense and aerospace environments, being able to endure extreme:
- Shock and Vibration
- Temperature (-55°C to +125°C)
Provides constant output performance for switching frequencies from DC to 50 kHz
Powerful MOFSET drive stage enables:
- High speed switching frequency up to 50 kHz
- High current, up to 30A
- High efficiency, up to an 8x improvement over earlier generation PWR-82331 motor drive
Pin compatible direct replacement for PWR-82331 hybrid motor drive

“Packaged in a small, ruggedized case, with a high-efficiency MOSFET drive stage, this high-reliability motor drive is an excellent choice for harsh, space constrained defense and aerospace environments requiring optimized performance” stated Michael Agic, DDC Product Line Manager, Motor Controllers.
