1. General

SPD871 DIN rail Bidirectional Energy Analyzer is designed special for energy managment system (EMS). By its DIN rail installation, it is very suitable to be used with breakers, contactors. Besides electrical energies, it may measure import and export kWh values.

It doesn't need CT, you may connect it to up to 100Amp directly. It has a 7 digits LCD display. By its front key and users may easily change display data. Every SDT871 has a RS485 interface and a impulse output, to transfer its measuring data to other master devices, such as PLC, data center computers.

SDT871 has good cost performance, as an intelligent unit and a digital electrical data collection unit, it has been widely used in many intelligent systems.
