In the mid 1990s, MCE introduced IMC (Intelligent Motion Control) for motor generators. This technological advancement incorporated two key elements of MCE’s product development strategy:

• The controller would be digital, and
• It would be characterized by unprecedented integration with the drive.

By 1995 development engineers at MCE were ready with the third element of their strategy: the introduction of a 12-Pulse elevator drive.

This new technology doubled the resolution of conventional six-pulse drives. Designed specifically for elevator applications, the integrated, digital drive cut current harmonic distortion in half while delivering an exceptional elevator ride.

System 12 benefits from literally hundreds of years of drive design expertise.

Features and Benefits

Superior Technology
The System 12 digital drive has been integrated with the IMC-SCR control to provide the very best technology available.

Designed for Elevators
The System 12 drive, designed and manufactured by MCE, is optimized specifically for elevator applications.

Single Source
One vendor for both drive and control; one telephone
number for technical support and problem resolution.

Non-Proprietary Freedom
Fully “Serviceable and Maintainable” equipment.

Lower Harmonic Distortion
System 12's Lower Total Harmonic Distortion, documented in extensive lab and field tests, provides a greater margin of protection from power corruption.

A Wealth of Drive Knowledge
