SY354 Power Meter

Features:

Real-time measurement for below power parameters:

*Voltage: split-phase phase voltage, line voltage and average voltage

*Current: split-phase current and average current

*Power: split-phase and total active power, reactive power, apparent power

Power factor: split-phase and total power factor

* Frequency: system frequency

* Active energy: active energy loss (EPI), released active energy (EPE)

* Reactive energy: reactive energy loss (EQL), released reactive energy (EQC)

* Power quality: voltage and current 3-phase unbalance, total harmonic distortion, 3rd~31th

odd harmonic component

* Access to 277/480V voltage directly, voltage transformer could be considered if higher voltage

* The primary side value of ×/1A or ×/5A CT can be programmed
