1. General
SPT660 power analyzer is designed special for electrical detection system in the field of electric, of mining, of infrastructure, of intelligent buildings etc.. It may measure all the parameters on the electrical networks, sucha as currents, voltages, active powers, reactive powers, apparent powers, frequency, power factors and 4 quadrant energies.
It has a big and high visible LCD display and it may be installed in any insdustrial space. It also has 4 front keys and users may easily change display page and set network parameters by them. Every SPT660 is equipped RS485 interface to connect master device, such as PLC, data center computers.
SPT660 has good cost performance, as an intelligent unit and a digital electrical data collection unit, it has been widely used in many intelligent systems, such SCADA, energy management systems.
