SDM530CT - Modbus/Mbus/MT

THREE PHASE FOUR WIRE MULTI-FUNCTION ENERGY METER

The model SDM530CT-MT is a CT type three phase multi-function energy meter with multi-tariff function. The unit measures and displays characteristic of three phase four wire supply, including voltage, current, frequency, power, active and reactive energy, imported and exported.

SDM530CT-MT can be configured to work with a wide range of CTs, giving the unit a wide range of operation. Built-in interfaces provides pulse and RS485 Modbus. Configuration is password protected. The Multi-tariffs funnction allows the meter to set RTC and time segments to measure kWh in different time zone.
