Energy meters with drum-type counters

 

 

Active Energy, 4-Wire 3-Phase Current

The U389 energy meter acquires active energy in 4-wire 3-phase systems. Import energy is transmitted to the logging system via a pulse output (S0) and can be read directly from a 7-digit drum-type counter mechanism. Current transformers connected with reversed polarity and direct connection are recognized and displayed as errors.

Electronic active energy meters

The energy meters may be universally used for the acquisition and billing of electrical energy in trade, household, industry and building management applications. Momentary circuit loads can be evaluated at any time using the additional instantaneous power display. Variants for direct connection (U1281, U1289) are designed for currents up to 65 A without the installation of additional current transformers. The variants for transformer connection (U1381, U1387, U1389) may be connected both to x/1 A and x/5 A current transformers.
