The Center Opening VVVF (Variable Voltage Variable Frequency) Door Operator is an advanced electromechanical system designed for modern elevator applications. Utilizing VVVF control technology, it ensures smooth, efficient, and quiet operation of center-opening elevator doors, enhancing passenger safety and ride comfort.
The VVVF controller adjusts voltage and frequency dynamically, optimizing motor performance for both opening and closing motions1.
Supports precise speed control with output frequencies ranging from 0.45Hz to 50Hz, allowing adjustable door movement speeds for different operational phases (acceleration, deceleration)14.
Panel Control: Manual operation via onboard buttons for maintenance and diagnostics1.
Terminal Control: Automated operation via external signals from the elevator control system, with configurable input commands (e.g., open/close, slow-close, safety sensor inputs)13.
Integrated safety signals, including door fully open/closed feedback and obstacle detection (e.g., via light curtains or safety edges)38.
Complies with elevator safety standards, featuring fail-safe mechanisms like automatic reversal upon obstruction detection58.
Rated for IP40 protection, suitable for installation in elevator hoistways or car tops1.
Operates in temperatures from -10°C to +40°C and humidity up to 90% RH (non-condensing)1.
Pre-configured wiring for encoders (e.g., 100 PPR incremental encoders) and motors simplifies setup36.
Diagnostic LEDs and 7-segment displays provide real-time status (e.g., door position, fault codes)
