Three phase electromechanical electric energy meter
U389
GMC Instruments
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.
* Acquires active energy
* Pulse output (S0) for energy import
* Electrical connection with reversed polarity is indicated by means of an LED
* Direct connection or via transformer
* 7-digit drum-type counter mechanism
* Can be installed in any position
* Compact dimensions
* Rugged design
* DIN rail mounting per EN 50022
