20A 220V DC Motor Speed Controller Governor with Precise Speed Control and Easy Panel Installation

220 V DC Motor Governor Key benefits Precise speed control for 220 V DC brush motors, allowing smooth adjustment from low speed to near full voltage. efficiency design for minimal energy loss, with an effective rate above 95 percent. Compact and lightweight form factor for easy installation in machine panels and retrofit projects. Main features and specifications Input voltage: AC 220 V Regulating output voltage: DC 10 to 210 V Maximum output current: 20 A; recommended continuous load: within 10 A Efficiency: above 95 percent Size: length 85 x width 58 x height 38 mm Knob inner hole diameter: 6 mm Net weight: 135 g Intended function: adjustable governor for 220 V DC brush motor speed control Why this product solves common problems Replaces fixedspeed systems with adjustable control to match motor speed to load requirements, reducing mechanical wear and improving process consistency. efficiency reduces wasted power and heat generation compared to less efficient controllers. Compact dimensions and standard knob shaft size make it straightforward to integrate into existing control panels or enclosures. Important usage notes Be sure to measure the output voltage under load. Noload voltage may appear unchanged and does not reflect operating voltage under motor load. Use only with 220 V DC brush motors. This product is not suitable for other motor types. Although the unit can deliver up to 20 A, continuous operation is recommended within 10 A to ensure stable performance and longer service life. Typical applications Speed control for small conveyors and material handling equipment driven by 220 V DC brush motors. Adjustable drive for workshop machinery and laboratory test rigs that use 220 V DC brushed motors. Fan, pump, or process equipment speed adjustment where a 220 V DC brush motor is installed. Installation and operation tips Ensure the knob shaft and knob inner hole are compatible with the 6 mm diameter. Mount in a ventilated location and confirm wiring for AC 220 V input and DC output to the motor is correct before powering on. Verify motor current draw and keep continuous load below 10 A when possible to maintain recommended operating conditions. This governor provides a reliable, efficient method to control the speed of 220 V DC brush motors while fitting into compact installations and standard control layouts.
