Monitoring device for power distribution network
SML, SMM, SMN
KMB Systems
These devices are designated to measure and monitor line-to-line and phase voltages, currents, active and reactive powers, true power factor, THD for both voltage and current one- and three phase LV, HV and VHV networks and sense the temperature inside a switchboard.
Characteristics
* true root-mean-square values of voltage and current (TRMS)
* active and reactive power, four quadrant presentation in compliance with IEC375
* both true power factor (PF) and power factor of fundamental harmonics (cos fi)
* Total Harmonic Distortion and harmonics of voltage and current up to the 20. order
* built-in temperature sensor
SML 33
* single-phase, two-phase, three-phase or Aron connection
* direct & undirect voltage connection
* optional remote RS-485 communication link
* panel mounted (SML) or DIN-bar mounted (SMM) version
