ECS3-1B
Three-phase Digital Energy meters - BASIC Connection through CT .../1 A till 2000/1 A
Installation must be carried out and inspected by a specialist or under his supervision. When working on the instrument, switch off the mains voltage!
• This family of devices provides a set of energy meters aimed to be connected via external current transformer suitable for every need. All the meters are equipped with an easy to read
LCD on which displays all the three phases active energy counters, with a red light LED which blink in proportion to the measured active energy and with a optocoupler that allows the
storage of energy on two different tariffs. Depending on the model a insulated M-Bus communication interface or a insulated Modbus communication interface are built in two solid state
relay which generate pulses proportional to the measured energy. Both M-Bus and Modbus communication interfaces offers a set of 59 measures.
