The maximum motor drive current is 30A. At 12V, the maximum power is 300W; at 24V, it is 400W; at 48V, it is 450W; and at 60V, it is 500W.\u003c\/li\u003e\n\u003cli\u003eMultiple Protections:The DC motor speed controller is equipped with a 30A automotive-grade fuse to effectively prevent short circuits at the motor interface. It adopts high-quality high-voltage MOS tubes, three 100V high-frequency low-resistance capacitors, and a precision aluminum housing, providing excellent heat dissipation, precise parameters, and ensuring long-term stable operation, offering dual protection for your motor and controller.\u003c\/li\u003e\n\u003cli\u003eDetachable Soft Wire:The PCB board integrates a RUN\/STOP\/BRAKE three-function toggle switch. Please turn on the RUN switch when in use for intuitive and convenient operation. The soft wire for adjusting the potentiometer is detachable (15cm\/5.9 inches in length), providing flexible and convenient installation.\u003c\/li\u003e\n\u003cli\u003eStable Operation:It features an optimized PWM circuit design with a wide duty cycle adjustment range, offering a speed regulation range of 0-100%. The motor operates smoothly without noise or vibration. It has a power indicator light for clear visibility of the working status. The precise welding process makes it suitable for applications requiring long-term operation.\u003c\/li\u003e\n\u003cli\u003eSafety Wiring Tips:The 7 - 70V PWM motor speed controller is specifically designed for DC brushed motors. It needs to be powered by a separate DC power supply and should not be connected to an AC power supply or used to drive brushless motors. When wiring, please note: P+\/P- connect to the positive\/negative terminals of the DC power supply, and M+\/M- connect to the motor (no need to distinguish positive and negative terminals; if the direction is incorrect, simply swap the two motor wires).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43384802148561,"sku":"BW-B0FXZQ215Y","price":21.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/71OgC8WOsDL.jpg?v=1791880166","url":"https:\/\/belmontwarehouse.com\/products\/makerele-7-70v-30a-pwm-dc-motor-speed-controller-1pc-adjustable-12v-48v","provider":"Belmont Warehouse","version":"1.0","type":"link"}
