Rectifier R3 Module 3HAC14549-3 ABB 380-480V AC

Technical Specifications

Product Overview

The ABB 3HAC14549-3 is a Rectifier R 3 module engineered for high-efficiency power conversion in ABB control cabinet systems and robotic controllers. Operating across an input voltage range of 380V to 480V AC (50/60 Hz) with a rated current capacity of 20 A, this high-performance unit achieves an energy efficiency exceeding 95%. Weighing 1.74 kg with physical dimensions of 21.5 x 22 x 27 cm, the 3HAC14549-3 is built with forced air cooling and complete electronic protection against overload, overvoltage, and short-circuit faults.

Key Features

• High-Efficiency Power Conversion: Converts 380–480V AC input to stable DC bus power with greater than 95% energy conversion efficiency.
• Comprehensive Fault Protection: Built-in circuitry actively guards against system overloads, input overvoltages, and direct output short circuits.
• Forced Air Thermal Management: Integrated forced air cooling maintains low internal thermal stress during continuous 20 A full-load operation.
• Global Compliance & Standards: Fully certified under CE, UL, and RoHS standards for seamless installation in worldwide control panels.

Installation Essentials

Mount rectifier into cabinet bay, terminate 380-480V AC supply lines, connect DC output bus, and verify forced air ventilation paths.
