The SDT670 DIN rail power meter is specially designed for energy management systems (EMS) and photovoltaic plants. Due to its DIN rail installation it is suitable for use with switches and contactors.
It can measure all parameters of electrical networks, such as currents, voltages, active powers, reactive powers, apparent powers, frequency, power factors and energies of the 4 quadrants. It does not require an external CT, but can be connected directly up to 100Amp.
It has a 7-digit LCD display. Through the front button, users can easily change the display data. Each SDT670 has an RS485 interface and 2 pulse outputs, for transferring measurement data to other master devices, such as PLCs and data center computers. SDT670 has good cost performance, and as an intelligent unit and digital electrical data collection unit, it has been widely used in many intelligent systems.
