Features: - Input Voltage: 220VAC - Output Voltage: 180VDC - Working Principle: Electronic speed controller designed for direct motor start-up; integrates with motor, miniature gear reducer, and speed sensor as a mechatronic unit. - Forward/Reverse Control: Motor rotation direction (forward or reverse) is controlled by connecting to M+ or M− terminals. - Mechanical Performance: Robust construction with wide speed adjustment range. - Installation: Simple panel-mount installation using screws. How to Use: 1. Before powering on, set the external speed potentiometer to zero to prevent inrush current that may damage the controller. 2. Terminal identification: - AC input terminals: Connect to 220VAC supply. - M+/M− terminals: Connect to motor leads. - P1/P2 terminals: Emergency stop function — shorting P1 and P2 stops motor operation. 3. Built-in fuse provides overcurrent and short-circuit protection. Replace with identical specification fuse if blown. Panel-mounted switches control motor start/stop only — they do not interrupt main power supply.
