EM24 3-Phase Energy Analyser
Three-phase energy analyzer for DIN-rail mounting with configuration joystick, frontal selector and LCD display. Direct connection up to 65A or via current and voltage transformers. It can be equipped with 2 digital outputs (pulse transmission or alarm function). In alternative the Modbus RTU or Dupline communication port and 3 digital inputs, the M-Bus communication, or the Modbus TCP/IP Ethernet ports are available. The wireless M-Bus version is the perfect solution when cabling is not possible.
Benefits
• Time saving set-up, by frontal joystick and selector.
• Error-proof installation, by self-power supply and phase sequence detection.
• Easy variable scrolling, by means of the front joystick.
• Wide interfacing capability, choosing among 2 pulse outputs, the RS485, the M-Bus, Dupline or the Ethernet communication port.
• Extended energy measurements, using total/partial or total/multi-tariff metering.
• Flexible installation, by means of the direct connection up to 65 A or the connection of 5 A current transformers.
• Extended alarm control on any available variable by means of up to two digital outputs.
• Accurate measurement. It is compliant with the international accuracy standard IEC/EN62053-21, and the IEC/EN61557-12 performance requirements (active power and active energy).
• Legal metrology, guaranteed by the MID approval
• Wireless communication, wireless M-Bus version allows remote data collection when cabling is not possible due to cost or installation requirements.
• Easy commissioning of wireless communication thanks to the test function of the joystick and to transmission counter for diagnostics.
