Midwest Motion Products Co. released the MMP20A-24V-RSP motor speed control module. The modular design includes a solid state PWM switch device that provides bi-directional, open loop, DC motor speed control.
According to the company’s press release, the control delivers 20 amps continuous current at 24 VDC with a 20–36V range. Measuring 4.5" x 3.1" x 1", the control can achieve the current required to power most brushed DC motors by delivering 240 watts of continuous output power. The latest design enhancement ensures up to 40 A of peak (momentary) current for a peak output power capacity of 480 watts.
The design is enabled to meet the IP-65 standard rating for resistance to harsh environments. The outer casing is brushed aluminum, and two 1/4" diameter thru-holes are provided for easy mounting to any flat (heat sinking) surface. Sets of four “quick connect” terminals are provided for connecting to power.
The control is designed for operation in applications including pumps, gearmotors, automotive and transportation industries, conveyors, food processing and others.
