This is a three-phase power analyzer with a built-in configuration keypad. It is particularly suitable for analyzing main, secondary, and energy metering electrical variables. It can be mounted on a DIN-rail or wall, with an IP40 (front) protection degree and a completely sealable housing. The measuring input terminals can accommodate cables with a cross-section area from 6 to 35 mm2 for direct connections up to 90A. The instrument's housing is designed to allow the addition of interface modules at any time, even when the instrument is already installed. The available modules include: - for all versions: pulses output; - only for versions with auxiliary power supply: analog output, RS485 port, or alarm output.
This manual describes the Energy Management WM22-DIN three‑phase power analyzer, its optional output modules and the various power‑supply configurations. It includes product description, input specifications, interface module details, software functions and wiring diagrams.
The document provides instructions for programming, display page configuration, front‑panel operation and installation on DIN‑rail or wall mounting, along with technical specifications such as protection rating, sampling rate and measurement accuracy.
