Three-phase energy meter with removable front LCD display unit. The same unit canbeusedeitherasa DIN-rail mountingorpanel mountingenergymeter. This general purpose three- phase energy meter is suit- able for both active and reactive energy metering for cost allocation but also for main electrical parameter measurement and retrans- mission (transducer func- tion).
