Certificate number: 0120 / SG S0216
 

Przeznaczenie
LE-03MQ CT is a static (electronic) calibrated electricity meter for single-phase or three-phase alternating current in a semi-indirect system. It is used for the indication and registration of the collected electricity and the parameters of the power supply network with the possibility of remote reading of indications via the wired network of the RS-485 standard. The meter cooperates with current transformers (CT) with 1 A or 5 A secondary current. The meter is configured via the configuration menu accessible from the front panel and through the communication port in accordance with the Modbus RTU programming functions.
