ABB UUD148 AE Measurement Interface Board

Core Performance & Industrial Application

The ABB UUD148 AE (3BHE014185R0001) is a voltage and current signal sampling interface board designed for ABB PCS6000 medium voltage converter.

It collects real-time voltage and current signals from the power stack, converts high power analog signals into low level feedback signals for control unit.

It has adjustable potentiometers R254 and R354 for I-output and U-output gain calibration to match different voltage and current ratios.

It supports multiple signal ratio options: 1/5A, 100V, 200V, 100V/√3, 200V/√3, flexible for different grid side configurations.

Equipped with status LED indicator array for channel diagnosis, convenient for on-site signal loop inspection and fault troubleshooting.

It transmits sampled measurement data to the main control board to realize closed-loop vector control, grid synchronization and protection logic.

It is widely used for offshore and onshore wind farm PCS6000 medium voltage converter control system maintenance.
