Original Quality DCB-II Drive Board For Otis OVF20CR 11-18.5kW Inverter GCA26800KG8 Elevator PCB Board Otis Gen2 Compatible

DCB-II Drive Board For Otis OVF20CR 11-18.5kW Inverter GCA26800KG8 Original Quality For Otis Gen2 Elevator Inverter System

Variable Frequency Drive Output: Converts three-phase industrial frequency power into adjustable voltage and frequency power to drive the asynchronous traction motor, adapting to the 0-2.5 m/s speed control requirements of the elevator, achieving smooth starting and braking, and saving energy.
Closed-Loop Control and Protection: Collects motor current/voltage/speed signals and implements speed closed-loop control through a PID algorithm; integrates overcurrent, overvoltage, undervoltage, overheating, and ground fault protection, immediately blocking the output and reporting the fault when a fault occurs.
Communication and Command Interaction: Interacts with the main control board (GECB) in real time via a serial bus to exchange operating commands, speed settings, and status feedback, supporting multi-speed operation and smooth switching to improve operating comfort.

Adaptable to special operating conditions: Compatible with the light-load/heavy-load compensation logic of the OVF20CR system, using weighing signals to achieve pre-torque output and reduce starting jolts; adapted to the space and heat dissipation requirements of machine-roomless/small-machine-room elevators.
Status monitoring and diagnosis: Real-time monitoring of inverter and motor operating parameters, storage of fault codes, support for on-site debugging and remote diagnosis, shortening maintenance cycles.
