Overview
The Fluke 1770 Series is a family of three-phase power quality analyzers (1773, 1775, 1777) built for power quality logging, troubleshooting and analysis in a future-proof IEC 61000-4-30 Class A Edition 3 package. It is engineered to meet the requirements of EN 50160 and IEEE 519 so studies stay compliant as standards evolve.
The instrument can be powered directly from the measurement circuit, removing the need for a separate outlet during long logging runs, and offers automatic measurements, a straightforward setup and a simplified reporting platform. The 1775 adds 1 MHz sampling and the 1777 raises this to 20 MHz for fast-transient capture up to ±8 kV.
Key Benefits
Class A Edition 3 compliance keeps studies defensible; 20 MHz sampling and 8 kV transient capture (1777) catch events simpler meters miss; circuit-powered operation enables long unattended logging.
Applications
AI data-center and colocation power quality audits; industrial and utility power quality studies; EN 50160 / IEEE 519 conformance; equipment troubleshooting; HVAC and motor-drive diagnostics.
