Features 【Stable Performance】: The dc motor speed controller is reliable, made of high-quality circuit boards, durable, stable performance, long service life, and quick start-stop response. 【Safety Protection】: The professionally manufactured inverter has multiple protection methods: Overcurrent, overvoltage, undervoltage, module failure, overheating, short circuit, input and output phase loss, abnormal adjustment of motor parameters, electronic thermal relay, etc. 【Appearance Design】: This speed governor shell is exquisite and practical, waterproof, small in size, light in weight, elegant in appearance, manufactured with standard technology, stable in performance, easy to use, and can be used outdoors. 【Convenient Wiring】: Equipped with screw terminals, and attached with power and motor pole indicator labels, it is convenient for wiring. The input voltage can be DC 10V to 60V, and the output voltage is 0-100% of the input voltage. The governor is quite convenient to set up . 【Precautions】: Make sure the positive and negative polarity is correct, otherwise the controller will be damaged. The dc motor controller inputs DC power and cannot be connected to ac power, otherwise it will burn out.
