SD300L Elevator VFD

SD300L – Elevator VFD is specially designed for vertical elevator applications. It features a unique open-loop vector control algorithm that ensures smooth, stable, and reliable elevator operation without the need for an encoder. With precise torque control and optimized ride comfort, the SD300L enhances both safety and user experience. It is an ideal solution for residential, commercial, and industrial elevator systems.

1. Smooth Start and Stop

Adopts advanced vector or VVVF control technology to ensure soft acceleration and deceleration, enhancing ride comfort.

2. High-Precision Positioning

Supports encoder feedback for closed-loop control, achieving accurate floor leveling within ±1 mm.

3. Fast Response & Strong Overload Capability

Designed for frequent start-stop cycles and variable load conditions, with short-term overload capacity up to 150–200%.

4. Comprehensive Safety Protections

Integrated brake control, fault self-diagnosis, overspeed, and stall protection ensure safe and reliable operation.

5. Energy-Saving Operation

Features intelligent sleep mode and regenerative braking to reduce energy consumption; optimized for use with permanent magnet synchronous motors (PMSM).
