Features: This PWM DC motor speed controller is suitable for DC 6-90V motor. Input protection: when input voltage is inverting, it does not work, it is good to protect the speed control board and power. Input DC 6-90v, the governor can only be used for brush motor. Dc governor, this product with digital display, display output voltage, and with power switch. This PWM DC motor speed controller comes with 20A ceramic fuse. The maximum current can reach 15A ,suggest within10A for use.The following is the corresponding power of different voltages: 6V=60W, 12V=120W, 24V=240W, 36V=360W, 48V=480, 60V=600W, 72V=720W, 90V=900W. Specifications: Suitable: DC6-90v (wide voltage) Rated current: 8A Maximum current: 15A Power range: 0.01-1000W speed range: 0-100% Frequency: 16 KHZ Weight: 470g Package Included: 1 x DC motor speed controller Note: Please note that the old and new type of the product will be sent randomly, and make sure you will not mind before ordering.
