Din rail three phase energy meter DZS300

Din rail three phase energy meter DZS300

It is used for energy measurements in three-phase electrical power network, which allows connection of additional relay contactors and DIN rail support. Also it support intelligent multi-tenant multi tarrif energy metering & billing system with Rs485 interface, also distribution and energy management solutions.


  • Measuring all parameters: three phase voltage, current, line voltage, frequency, active power, reactive power, apparent power, power factor, active energy, reactive energy, bidirectional energy metering
  • Direct connected, suitable for various wiring modes under high or low pressure environment
  • Analysis of current/voltage harmonic (231ties )
  • Multi tariff (optional), available for querying past 12 months' energy
  • 1* RS485, Modbus RTU / DL645 adaptive protocol
  • 1* energy pulse output
  • LCD display
