Chroma 66205 Digital Power Meter

Overview

The Chroma 66205 is a second-generation single-channel digital power meter from the 66200 series, engineered for highly accurate power measurements meeting IEC 62301 and EN50564 standards. It features state-of-the-art DSP technology with 16-bit converters and sampling rates up to 250 kHz, supporting voltage ranges to 600V and current measurement up to 30A.

The 66205 delivers exceptional performance for R&D, production, and quality control applications requiring precise power analysis. Its Smart Range function automatically optimizes measurement accuracy during power integration, while comprehensive harmonic measurement capabilities (up to 100 orders) ensure compliance with international standards and precise analysis of switching power supplies and modern electronic devices.
