Motor Speed Controller for 220 VAC to 180 VDC motor applications Key benefits Precise speed control: Allows smooth adjustment of DC motor speed for stable operation in mechanized systems. Protection built in: Includes overcurrent and shortcircuit protection to reduce risk of damage during faults. If the protective element melts, it with the same specification. Easy panel installation: Compact ABS housing and panel screw mounting make it simple to fit into control panels or equipment enclosures. Direction control: Supports forward and reverse motor rotation by changing connections to the M+ and M output terminals. Main features and specifications Item type: Motor Speed Controller Material: ABS housing for durability and electrical insulation Input: 220 VAC Output: 180 VDC Appearance size: Approx. 100 x 60 x 114 mm Opening hole size: Approx. 81 x 53 mm Installation method: Panel screw mounting Terminals: Rear AC terminals for mains input; M+ and M for DC motor output; P1 and P2 for emergency stop Protection: Overcurrent and shortcircuit protection built into the controller Function: Direct start DC voltage output, suitable for use with motors, miniature gear reducers, speed sensors and other mechatronic assemblies Control notes: The front panel action switch controls motor start and stop only. It does not switch the main power supply. Important usage instructions Before powering the unit, set the external speed control knob to zero to avoid instantaneous current that could damage the controller. AC terminals on the rear are for AC input voltage. Connect your DC motor to M+ and M for output power. To change rotation direction, swap the motor leads between M+ and M. P1 and P2 form an emergency stop terminal. Shorting P1 to P2 will stop the motor immediately. If the builtin protective element melts after an overcurrent or shortcircuit event, it with one of the same specifications. Performance and compatibility Designed for DC motor systems requiring regulated DC output from a 220 VAC mains source. Well suited for small to medium mechatronic assemblies that include motors, gear reducers, and speed sensors. Offers a wide speed range and reliable mechanical performance for industrial and hobby applications that need controlled motor speed and direction. Typical use scenarios Conveyor drive control in light manufacturing or assembly lines, where adjustable speed and emergency stop capability are required. Rotary actuators or gearbox driven mechanisms in test rigs or automation prototypes that need smooth start and stop with direction control. Small machine tools or workshop equipment that use DC motors and require panelmounted speed adjustment and overload protection. Packing list 1 x Motor Speed Controller This controller provides a compact, panelmount solution for converting 220 VAC to regulated 180 VDC motor output with builtin protection and emergency stop functionality. Follow the usage instructions and wiring notes to ensure correct and safe operation.
