Information

Overview Manuals Technical notes Product Applications Electrical Connections & Wiring

Features:

  • External DC Voltage Measurement for H1...H5
  • Two Resistor Chains for Voltage Reduction
  • External Mounting Outside Drive Module
  • Dual DC Voltage Terminal Connections (X1 and X2)
The SDCS-UCM-1 3ADT220090R0008 specifically for ABB DCS880 thyristor power converters in frame sizes H1 through H5. In these drive sizes, the DC voltage measurement is integrated on the SDCS-PIN-H01 board, making it impossible to split the DC voltage measurement and measure externally directly at the motor. This limitation causes problems when using a DC-breaker or US-style DC-contactor, because an exact DC voltage measurement cannot be obtained when the DC-breaker or contactor is open.

The SDCS-UCM-1C 3ADT220090R0008 ABB MEASUREMENT BOARD may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

With the help of the DC measurement set SDCS-UCM-1 for H1...H5, external DC voltage measurement at the motor terminals becomes possible. The board contains two resistor chains which are connected to the DC voltage (armature circuit) of the motor. The voltage reduced by the resistor chain is connected to analog input AI3 (XAI: AI3) of the DCS880. The DC voltage is wired to connectors X1 and X2, where the positive DC voltage (C1) is connected to connector X1 and the negative DC voltage (D1) to connector X2. The connection of X1 and X2 is done according to the nominal motor voltage.

Cable Selection: Utilize twisted, shielded pair cables for instrumentation feedback lines to minimize electromagnetic interference (EMI).
Ground Routing: Connect the board’s protective earth (PE) terminal straight back to the main drive chassis ground plane.
High-Ohmic Segregation: Keep high-voltage resistor measurement paths separate from low-voltage control or communication ribbon cables.

FAQs

  • What is the SDCS-UCM-1C ?

    +
    The ABB SDCS-UCM-1C (Part ID: 3ADT220090R0008) is an essential measurement and excitation circuit board utilized in ABB DC drive systems
  • What is the primary function of the SDCS-UCM-1C board?

    +
