ABB Power Supply Module for ACS800 and DCS800 Drive Systems

Product Overview

The NGPS-02C is a high-performance auxiliary power supply module manufactured by ABB, designed specifically to provide stable 24V DC control power for ABB drive systems including the ACS600, ACS800, and DCS800 series . This module functions as the critical power backbone for drive control circuits, converting incoming AC mains voltage (typically 85-264V AC) into a regulated 24V DC output that powers the RMIO control board, operator panels, auxiliary relays, and excitation circuits . As a key component of ABB’s drive architecture, the NGPS-02C ensures that control electronics receive clean, isolated power independent of the main drive power stage, enhancing system reliability and operational stability.

The NGPS-02C represents an upgrade from its predecessor, the NGPS-02, featuring improved wide-range input voltage tolerance that makes it particularly suitable for installations in regions with significant grid voltage fluctuations . This power supply module is designed for cabinet installation using DIN rail or dedicated mounting brackets, and is not hot-swappable, requiring proper power-down procedures for installation or replacement . The NGPS-02C incorporates comprehensive protection features including input overvoltage/undervoltage protection, output overcurrent limiting, short-circuit protection, and thermal shutdown, ensuring reliable operation in demanding industrial environments. With a typical power capacity of approximately 240W and output current capability of around 10A, the NGPS-02C provides ample power for most drive control systems .
