Specifications are subject to change without notice WM22-DINDS1003 1 Product description Three-phase power analyzer with built-in configuration key-pad; Particularly indicated for the analysis of main, secondary and energy metering electri- cal variables. Housing for DIN-rail or wall- mounting, IP40 (front) pro- tection degree. Completely sealable housing. In case of dir ect connection up to 90A, the measuring input terminals are suitable for cables with a cross-sec- tion area from 6 to 35 mm The special design of the instrument’s housing allows to add at any time the inter - face modules, even when the instrument is alr eady installed. The following modules are available: - for all versions: pulses out - put; - only for the versions with auxiliary power supply: analogue output, RS485 port or alarm output.
