TB20 Energy Meter

Das Funktions-Modul Energy Meter nimmt alle wesentlichen Messwerte aus AC 230 V-Netzen bez?glich der Strom- und Spannungsmessung auf. Die Eingangsspannungen (3 Phasen + N) k?nnen direkt an das Modul angeschlossen werden.
Neben allgemeinen Statusinformationen k?nnen bis zu 7 Messwerte im Eingangsabbild durch die Parametrierung eingeblendet werden.
Der steuerbare Stromz?hler wird bei Ausfall des Systems nichtfl?chtig gespeichert.

Configuration errors

Input currents are coupled through current transformers. The Energy Meter module is designed for a maximum secondary current of 1 A.
Other rated secondary currents, as well as the use of Rogowski coils, are available upon request.
