Description

The ABB 61298487 is a dedicated DSU CONTROL NDSC-01 control board engineered for the ACS 600 frequency converter series. It serves as the primary hardware processing unit for Diode Supply Units (DSU) managing six-pulse and twelve-pulse half-controlled rectifier bridges. The device directly supervises high-ohmic AC line voltage sensing, DC busbar measurements, synchronization timing, and gate pulse generation for the power semiconductors. It integrates software logic to ensure seamless execution of charging modes and normal operational tracking within continuous current configurations.

Features

Complete control board layout integrating three galvanically isolated digital inputs and three relay outputs.
Onboard high-ohmic resistor chains supporting high-voltage tracking up to actual network levels without standard external scaling.
Dedicated DDCS communication link interfaces and localized diagnostic tracking via a 7-segment hardware display.
Configurable operational parameters utilizing twin 8-way integrated DIP switches for rapid configuration adjustments.

Applications

Half-controlled rectifier bridge tracking within continuous industrial DC link assemblies.
Multi-pulse system coordination for parallel diode supply modules.
Active phase synchronization oversight and system protection routines in industrial frequency converters.

Installation Guidelines

Isolate all electrical source networks before commencing mounting or terminal connection routines.
Fasten the card assembly inside the chassis envelope using original metallic mounting supports to establish functional ground contacts.
Set the target configuration criteria matching application specifications via the 8-way integrated DIP switches before operational initialization.
Route internal wiring clear of raw high-voltage power paths to lower EMI coupling risks across the 10 ms low-pass terminal filters.

Product Documentation

Technical Datasheet (PDF) Complete specifications and technical drawings.

What is the voltage range supported by the digital inputs on the module?

The digital inputs are self-adaptive and support an operating voltage range from 24 VDC up to 230 VAC.

What happens if an earth fault is identified by the device?

If an earth fault current exceeds the software limit, the device executes a protective trip loop and lists code F05 on the 7-segment display.

Are the actual main circuit voltage signals on the board isolated?

No, the main circuit actual voltage monitoring loops for lines U1, V1, W1, Uc1, and Uc2 are not galvanically isolated.
