Speed Limiters

Precision Speed Limiter Module – Rapid Response & Robust Control

The Speed Limiter Module is a high‑performance, low‑profile device designed to enforce strict velocity limits on DC motors, gearboxes, and linear actuators in industrial, automotive, and robotics applications. Built with a micro‑controlled sliding‑window algorithm, it continuously monitors the RPM or position sensor signal and injects a proportional braking torque or voltage reduction to keep the motion within pre‑defined boundaries, ensuring operator safety and equipment longevity.

Engineered for harsh environments, the unit features a rugged 70 °C ±15 % supply range, galvanically isolated inputs, and a configurable fault latch that triggers an instant shutdown or safe‑stop sequence. With a maximum current rating of 15 A and a thermal design that keeps junction temperatures below 120 °C, it delivers reliable performance under heavy load cycles, while its compact 30 mm × 18 mm footprint fits seamlessly into tight gearboxes and control panels.

• Max In‑Volt Input: 28 V DC (±5 %)
• Max Current: 15 A continuous, 25 A peak
• Response Time: 200 µs to over‑limit detection
• Common Use Case: Preventing runaway speed in conveyors, rotating drum machinery, and test rigs where exceeding velocity thresholds could cause material ejection or component failure.
