SDM320C-DI measures and displays the characteristics of single phase two wire (1p2w), including voltage, frequency, current, power, active and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured over preset periods of up to 60 minutes.
The meter is Max. 100A direct connected and do not need to connect with external current transformers(CT).
An RS485 communication port is available on the meter for remote data transmission.
