H-TRONIC automaattinen käynnistys- ja jarrunohjaus rakennussarja 199354

This H-TRONIC automatic start and brake control kit stands out by giving you precise, adjustable acceleration and deceleration for brushed DC motors—an essential upgrade for smooth, realistic operation in model railways, automation, and robotics. Unlike simple on/off switches, it ramps motor speed gradually, preventing jerky starts and sudden stops that can derail trains or damage mechanical components.

Highlights

• Adjustable acceleration and deceleration time (approx. 0–10 seconds each) via onboard potentiometers
• PWM output for efficient, low-noise motor control
• Wide 12–24 V DC operating voltage, compatible with common power supplies
• Handles up to 3 A continuous, 5 A peak current
• Positive switching input—works with switches, relays, or control panels
• Compact PCB (70 x 50 mm) with screw terminals for easy wiring
• Soldering kit: all components included, assembly required

In daily use

Wire the module between your power source and motor, set the desired acceleration and braking times with the two trimmers, and trigger it with a simple switch or relay. The motor will smoothly ramp up to full speed and gently coast to a stop, adding realism to model train layouts or protecting mechanical systems from abrupt motion. The low idle current (approx. 10 mA) makes it suitable for battery-powered projects.
