Frequently Asked Questions

What is a frequency inverter used for in elevators?

A frequency inverter (or AC drive) controls the speed and torque of the elevator motor by adjusting the frequency and voltage of the power supply. This enables smooth acceleration, deceleration, and precise floor leveling.

Can STEP inverters be used for escalators?

Yes, our escalator integrated drive and controller systems are specifically designed for escalator applications, offering energy-saving modes, soft start/stop, and remote diagnostics.

Do you offer remote monitoring solutions?

Yes, STEP offers a remote elevator monitoring system that allows real-time tracking of elevator status, fault alerts, and predictive maintenance via cloud-based platforms.

Are your products compliant with international standards?

Yes, our products meet international safety and performance standards, including CE, UL, and ISO 9001 certification. We adhere to strict quality control throughout manufacturing.
