1. General

      SDT670 DINrail power analyzer is designed special for energy managment system(EMS). By its DIN rail installation, it is very suitable to be usedwith breakers, contactors. Besides electrical energies, it maymeasure all the parameters on the electrical networks, such ascurrents, voltages, active powers, reactive powers, apparentpowers, frequency, power factors and 4 quadrantenergies. 
       It doesn''t needexternal CT, but we may connect it to up to 100Amp directly. It hasa 7 digits LCD display. By its front key and users may easilychange display data. Every SDT670 has a RS485 interface and 2impulse outputs, to transfer its measuring data to other masterdevices, such as PLC, data center computers. 
SDT670 has good cost performance, as an intelligent unit anda digital electrical data collection unit, it has been widely usedin many intelligent systems.
