SDM54 Modbus/Mbus/2T

THREE PHASE MULTI-FUNCTION POWER ANALYZER

The SDM54-M is a 3 Module RS485 Modbus Din Rail Three Phase MID Energy Meter with backlit LCD display. It measures and displays the characteristics of single phase two wires (1p2w) and three phase four wires(3p4w) supplies, including voltage, frequency, current, power, power factor, active and reactive energy, imported or exported. Energy is measured in terms of kWh and kVArh. Maximum demand on power and current can be measured over preset periods of up to 60 minutes, mini in size (54mm width) , popular withthree phase EV charging, PV solar system, particularly Zero Export system.

The unit has been approved to meet the requirements of EU Directive 2014/32/EU.
