The SDM54 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 pre-set periods of up to 60 minutes. The SDM54 supports max.100A direct loads per phase, with dual tariff management options available. The meter is designed for DIN-rail mounting, housed in a 3 DIN module case, with IP51 front protection. The meter is optionally equipped with pulse outputs, RS485 Modbus port or M-bus port. Configuration can also be done via keypad, which is password protected.
