Control Techniques MP350A4 DC Drive – Reliable, Regenerative Motor Control

The Control Techniques MP350A4 DC Drive is engineered for precision and durability in demanding industrial environments. Designed for 4-quadrant operation, it provides full regenerative capability, allowing smooth acceleration, controlled braking, and efficient energy recovery. With a continuous current rating of 350 A and 380–480 V three-phase input, the MP350A4 delivers dependable performance for large DC motors and heavy-duty automation systems. Its digital control platform ensures accurate speed and torque regulation, making it a trusted replacement drive for legacy systems or a reliable choice for new installations.

Technical Highlights and Key Features

Built to handle intensive industrial applications, the MP350A4 integrates advanced control technology with robust protection features. The drive operates with 380–480 V AC input and delivers a continuous 350 A armature current, supporting motors up to approximately 145 kW (195 HP). As a 4-quadrant unit, it can provide full regenerative braking—returning excess energy to the supply line instead of dissipating it as heat—maximizing efficiency and reducing energy costs.

Operators benefit from a user-friendly digital interface that simplifies parameter setup, commissioning, and diagnostics. Integrated safety systems guard against overcurrent, overload, overheating, field loss, and short circuits, ensuring reliable long-term operation. The MP350A4 is also CE and UL certified, making it compliant for use in global industrial environments.

Industrial Applications

The versatility of the MP350A4 DC Drive makes it suitable for a wide array of industrial processes. In material handling, it provides precise control for conveyors, hoists, and lifting equipment where smooth starts and stops are critical. Manufacturing facilities rely on its robust torque regulation for roll mills, extruders, and mixers, while textile producers use it to manage spinning, winding, and dyeing machinery. The drive is equally effective in printing applications, delivering consistent motor performance for presses and unwind systems that demand exact speed and tension control.
