Modular with 6 DIN width, NA003 complies with the CEI-021 standard which requires its use for all energy production plants greater than 11.08kW.
Equipped with universal 24-240VAC / DC power supply, this instrument has in memory not only the parameters of the CEI-021, but all the standards of the main countries, thus offering a unique solution for installation in any country.
NA003 performs continuous control of the mains voltage and frequency and intervenes in the event of anomalies or exceeding of the thresholds set by the reference standard.
The instrument is fully programmable locally, thanks to the front keypad (sealable), and password protected to exclude possible tampering. It is always possible to change the preset thresholds, in this case it will be indicated that you are outside the reference standards of the loaded standard.
