The Alternating Current Single-phase Asynchronous Motor Electronic Speed Controller is a high-quality motor speed controller designed for durability. It features a small size, high accuracy, and a long service life. With its stepless speed regulation, it can be easily used in conjunction with domestically produced single-phase asynchronous motors to achieve feedback constant speed and precise speed control. The speed controller has a power rating of 400W, providing stable performance. It offers a wide speed range of 90-1700r/min at 60Hz. The slip rotation knob design allows for easy adjustment of the working speed. There is also a convenient one-button on/off switch for the motor. It is important to disconnect the power supply when the motor is not in use for an extended period of time. This speed controller is suitable for various applications such as packaging, printing, food, electronics, instrumentation, equipment, and clothing industry production lines. It can be used as a speed control drive device to regulate the speed of motors. The controller operates on a power supply of 220VAC, 50/60Hz and has a temperature range of -10 to 50 degrees Celsius. The Alternating Current Single-phase Asynchronous Motor Electronic Speed Controller comes with a compact size of 113 * 100 * 60mm and weighs 252g. The package includes 1 Speed Controller and has dimensions of 120 * 105 * 83mm with a weight of 284g.
