Model V900 DC Type SCR

The V900 SCR provides solid state power control in a closed-loop system for most geared and gearless elevators with DC motors. Precise speed regulation better than +/- 1% is provided using quadrature encoder feedback and a closed loop drive design.

The V900 DC system is equipped with line regenerative, full-wave, four-quadrant digital drive technology. This provides significant power savings vs conventional VVDC technology, as well as improved performance, reliability and extended service life. V900 DC technology is ideal when a DC motor is retained during modernization.

Simplified Design Delivers Reliable Code Compliance

A dramatic reduction in the number of relays, discrete parts and consolidation of three PC boards into one makes the V900 system reliable and serviceable. EN 60947-5-1 force guided relays are incorporated to ensure code compliance.

Microprocessor Board

EC's forward-looking system architecture provides universal backward compatibility. Proven components and technology are always used to ensure years of field reliability.

PVF Position Velocity Feedback Option

To satisfy the most demanding ride quality requirements a digital dual-feedback Position Velocity Feedback option is available. PVF provides microcomputer based position and velocity feedback for higher speed geared and gearless elevators in closed loop applications.
