Variable Speed Controller PWM DC Brush Motor Governor with Alarm and Reverse Protection

Item Type: Speed Controller Input Voltage: 12-50VDC Maximum Current: 20A Speed Regulation Mode: PWM The Base Frequency has 3 Levels: The jumper shorts the left 2 pins is 2.1KHZ the 2 short pins on the right are 2.9KHZ and the 3 pins are short-circuited 11.1KHZ. The default is 2.9KHZ when shipped 2 Control Methods: Control whether the motor is controlled manually by an jumper switch or an external PWM signal is connected to the control card or PLC. External PWM input requirements are: Level 3.5-12V VPP frequency 1K-5KHZ duty cycle is 0% -93% Input Interface Specifications: The internal resistance is 330 ohms when connected to a PLC. To connect a 1.5-2.7K ohm resistor in series. Connect directly to a 5V level motion control card such as MACH3. Alarm Output Interface Specification: The Maximum Driving Current is 12MA. Super High Power Control: Maximal 20A it is recommended not to exceed 15A
