Product Overview

The ABB ECHAM 086369-001 is a specialized Harmonic Attenuation Module (HAM) engineered to optimize power quality within sophisticated industrial electrical networks. Developed under the Accuray product line, this high-performance component is designed to suppress electrical noise and harmonic distortion generated by non-linear loads, such as variable frequency drives and large-scale switching power supplies. By stabilizing the sine wave of the power distribution system, the ECHAM module protects sensitive downstream electronics from thermal stress and operational interference.

Manufactured in Sweden, the 086369-001 is a critical asset for Distributed Control Systems (DCS) and power management infrastructures where "clean" power is a prerequisite for system uptime. Its lightweight, ultra-slim form factor allows for high-density mounting in standard electrical enclosures, making it an ideal choice for both modular factory upgrades and new-build infrastructure projects.

Performance and Harmonic Mitigation

The ECHAM 086369-001 focuses on the mitigation of Total Harmonic Distortion (THDi), specifically targeting the 5th order harmonics (250Hz) which are frequently responsible for overheating in motors and transformers. The module provides a substantial reduction in distortion—exceeding 70%—through a precisely tuned 0.5mH inductance core.

Built to survive the electrical transients typical of heavy industry, the module features a high surge withstand rating of 25kA. This ensures that the module remains functional and protective even during localized power disturbances or switching surges. Its wide operating temperature range and resistance to non-condensing humidity ensure consistent performance in environments ranging from climate-controlled server rooms to rugged industrial plants.
