RioRand 7-70V PWM DC Motor Speed Controller 30A - Low Heat Aluminum Housing for Brushed DC Motors, DIY Projects & Small Electric Devices (Extra Fuse Included) Green

• 7-70V Wide Voltage & 30A High Current – For brushed DC motors only (not brushless/AC power). Supports 1%-100% duty cycle (12kHz PWM) & 500W max output. Power limits: 12V≤250W, 24V≤350W, 48V≤450W, 60V≤400W. Reserve 5-10V margin (do not overload).
• Low Heat & Durable Design – Equipped with high-voltage MOSFET, 3x 100V capacitors & aluminum housing. Low heat generation, easy component replacement, no vibration/noise – reliable for long-term use. Extra fuse included for backup.
• Accurate Voltage Measurement Tip – Output voltage must be measured with a loaded motor (no-load readings = input voltage, which is normal). Suitable for DIY robotics, small tools, fans, mini pumps & hobby projects.
• Easy Wiring & Safe Operation – Input DC polarity must match (reverse = damage); motor output no polarity (swap wires for direction). On-board run/stop/brake switch + detachable 15cm potentiometer wire.
• Trusted Performance & Upgraded Design – Smooth speed transitions, overload current protection & stable operation. Modified to address common use issues –Suitable for hobbyists & DIY enthusiasts.

Brand:RioRand Product Name :DC Brush Motor Speed Controller DC Controller is required in the following situations: 1. Need a wider speed range. 2. Need fast dynamic response process. 3. Automatic smooth transition is required during acceleration and deceleration. 4. High torque is required when low speed operation is required. 5. Good excavator characteristics are needed, which can automatically limit the overload current to the set current 6.And it is a DC Motor Speed Controller,Not a Voltage Controller
