ABB UAC383AE01 HIEE300890R0001 LD-MUB-01 Measurement Unit Board

UAC383AE01 HIEE300890R0001 LD-MUB-01 Measurement Unit Board

The UAC383AE01 measurement unit board is mounted on the EXU ( Excitation Unit ) swivel frame cabinet, between the measurement sensor and the CCB board ( Converter Control Board) with a lateral connection.

This measurement unit board is used to measure signals and output signals between the rectifier control board and the measurement interface board, it can form an electrical interface between the power stage and the electro-weak part.

The measurement unit board is controlled by CCB board, this board contains 3 analog-to-digital conversions and can read in 8 analog signals simultaneously.

One or two (brushless excitation) measurement unit boards are able to be connected to the CCB board via digital expansion channels. On the MUB boards, the addressing capability is ensured by jumper X4.
