Electromen OY 3 Phase DC Motor Controller 11V dc to 42 V dc, 40A , EN - 55022B EM-347

Electromen OY EM-347 is a high-performance 3 Phase DC Motor Controller designed for brushless DC motors operating at supply voltages ranging from 11V dc to 42 V dc and capable of handling currents up to 40A. The controller features a MOSFET power stage that delivers high efficiency and generates very low RF noise, making it ideal for environments sensitive to electromagnetic interference.

This motor controller supports 120° commutation and a true four-quadrant power stage enabling regenerative braking. This braking method allows the supply voltage to be controlled via a braking resistor or, in battery-supplied systems, to return energy back to the battery, eliminating the need for a resistor.

Control inputs include digital and analog signals (0-5V or 0-10V), allowing proportional speed and direction control tailored to the application. Two NPN outputs provide fault and overcurrent indications, while various input and output functions are configurable through parameters.

Safety features include overvoltage, undervoltage, and overtemperature protection. The controller offers both open and closed loop modes, with closed loop utilizing hall sensor feedback for accurate speed regulation. Start and stop ramp settings, as well as speed range adjustments, are available in both modes. The analog input is filtered, enabling direct PWM signal control from PLCs.

A cooling fan output switches on automatically when the controller temperature exceeds 65°C to ensure reliable operation under high loads. Parameter programming is available via three options: the EM-236 interface unit, EM-268 PC program with Menthol-Lite software, or the EM-326 Menthol-App for smartphones.

This controller is DIN rail mountable and complies with EN-55022B standards, confirming its suitability for industrial automation, electrical control gear, manufacturing processes, and other commercial applications requiring precise brushless DC motor control.
