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.
