YF-20 Speed Controller 7-30V DC Digital Display Driver Control Module for Stepper Motor Speed Control

General Description The YF-20 speed controller is a digital control module designed for controlling the speed of stepper motors. It connects directly to the motor without requiring an external driver, providing a simple and effective solution. This controller is made with a high-quality printed circuit board and is equipped with a digital display that shows the percentage of the actual speed relative to the maximum speed. Technical Specifications Model: YF-20 Control Voltage: 7~30V Current: Up to 2A Compatibility: Two-wire, four-wire, and 42.57 stepper motors Speed Regulation: 0.1~999 RPM (Typical maximum speed for 42.57 motors: approximately 350 RPM) Adjustable Angle: 1~9999 degrees (360 degrees in a circle) Other Information
