These modules are for the acquisition and evaluation of measured values according to EN 50160 or EN 61000-2-2, EN 61000- 2-4, EN 61000-2-12. It extends the measurement to include flicker, voltage dips and interharmonics. The evaluation is stored in a separate PQ archive. In a separate archive, limit value violations and voltage events (overvoltages, undervoltages, voltage interruptions) can be archived. Units with this module become power quality analysers class S or class A according to IEC 61000-4-30.
