DC 10–60V PWM Speed Controller

Compact unit measuring 88 × 59 × 40 mm (3.46 × 2.32 × 1.57 in), weighing approx. 150 g. Operates on DC input only — 10 V to 60 V — with output voltage linearly adjustable from 0% to 100% of input. Uses B100K potentiometer for smooth speed tuning. Continuous current rating: 10 A; peak capability: 20 A. PWM frequency: 25 kHz. Minimum speed threshold: 5%; full range control up to 100%. Tap hole diameter: 8 mm (0.31 in). Housing is fully waterproof and mechanically robust, enabling direct mounting in open-air or damp locations. Includes screw-type terminals with embossed polarity indicators for power (+/–) and motor (M+/M–) connections. Strictly for DC supply — AC connection causes irreversible damage. Polarity reversal also leads to immediate failure. Supports common low-power DC motors: 12 V units up to 120 W (e.g., fans, small actuators), 24 V units up to 240 W (e.g., wheelchair drives, solar trackers). Not suitable for brushless (BLDC) or AC motors. Ideal for makers, maintenance teams and small-scale automation where reliability, simplicity and weather tolerance are prioritised over smart connectivity.
