Eastron SDM630MCT Information The Eastron SDM630MCT is a high-accuracy multifunction power meter that can be used to measure a wide range of electrical parameters, including current, voltage, power, energy, and harmonics. It is available in both single-phase and three-phase models, and can be configured for either 1p2w or 3p4w systems. The meter features a built-in display that shows real-time readings for all measured parameters, as well as a RS485 Modbus RTU port for remote monitoring and data logging. Here is an overview of the Eastron SDM630MCT: Introduced: 2018 Current rating: Up to 100 amps continuously Accuracy: Class 1 / B Measurement parameters: Current Voltage Power (active, reactive, apparent) Energy (active, reactive, apparent) Power factor THD Harmonics (up to the 50th order) Communication: RS485 Modbus RTU, dual pulsed outputs Display: Blue backlit LCD Mounting: DIN rail
