Product Details
Product Details
The RioRand PWM DC Motor Speed Controller is specifically engineered for brushed DC motors operating within a voltage range of 7 to 70 volts. It features an adjustable duty cycle from 1% to 100%, enabling precise speed control without stalling at low speeds. The controller is constructed with high-voltage MOSFETs and integrates three 100V capacitors, ensuring safety with defined maximum thresholds: 12V ≤250W, 24V ≤350W, 48V ≤450W, 60V ≤400W, and a maximum current of 30A.
Performance Features
This device utilises a 12kHz PWM drive circuit that minimises motor whine and offers smooth acceleration across all speed settings. It is enclosed in a sturdy aluminium housing that effectively dissipates heat, making it suitable for extended use in various applications such as workshop tools, agricultural pumps, and marine trolling motors.
Installation and Usability
The controller comes with a 15cm (5.9 in) detachable potentiometer ribbon cable, enhancing flexibility for control panel setups. Additionally, it incorporates a Run/Stop/Brake rocker switch for immediate control functionality. This design is perfect for retrofitting ventilation fans, golf cart accessories, mini drill grinders, and automated robotic systems.
Wiring and Safety Features
Foolproof wiring is facilitated by clear terminal markers that help to prevent reverse-polarity damage on the DC input. The motor outputs are non-polarized, allowing easy swapping of wires for changing the rotation direction. An onboard power status LED and a replaceable inline fuse provide additional safety by protecting against unexpected current surges during loads.
Tuning and Power Management
Real-load tuning is essential for accurate performance as the no-load output voltage will match the input voltage. Speed adjustments and voltage drops should be measured while under active load. Note that setting the potentiometer to the lowest position will not fully cut off power; the main power source must be disconnected for a complete shutdown.
