Energy consumption meter 3-phase LE-03MQ CT F&F
Description LE-03MQ CT
Three-phase LE-03MQ CT, semi-direct, bi-directional, four-quadrant measurement of electricity and network parameters, MID directive compliant, Modbus RTU communication interface.
Compatibility
Directive 2004/22/EC
Certificate number: 0120/SG S0216
Purpose
LE-03MQ CT is a static (electronic), calibrated electricity meter for single-phase or three-phase alternating current in a semi-direct system. It is used for indication and registration of consumed electricity and parameters of the supply network with the possibility of remote reading of indications through a wired network of RS-485 standard. The meter works with current transformers (CT) with secondary current of 1 A or 5 A. The meter is configured through the configuration menu accessible from the front panel and through the communication port in accordance with Modbus RTU software functions.
