The ABB QA/S 3.64.1 EQmatic Energy Analyzer is the 64-meter M-Bus master in the same 4 MW MDRC housing as QA/S 3.16.1. It logs, stores, and analyses electricity, gas, water, or heat meters over M-Bus and serves a HTTPS web interface for dashboards, exports, and APIs.

Choose this SKU when the installation exceeds 16 M-Bus slaves. For smaller plants see QA/S 3.16.1. ABB EQ A- and B-series meters auto-detect; other slaves are configured in the browser.

Key Features
