1. General
SPM520 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 single phase, such as current, voltage, active power, reactive power, apparent power, frequency, power factor and active & reactive energies.
It has 3 red LED 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 SPM520 is equipped RS485 interface to connect master device, such as PLC, data center computers.
2. Function
* With 3 high Red LED display, which may be well visible in any somber space;
* Measuring 9 parameters on single phase: IL, UL, Fr, P, Q, S, PF, import & export kWh, inductive & capacitive kvarh
* With RS485 interface to connect master device, slave address & baud rate may be programmable;
* Programmable CT, PT ratio and wiring mode, it may be used on different AC networks;
* With plug-in connectors, easy to wiring;
* With StandardeL PC software, the user may easily read and SPM520 data and program its parameters by computer.
