Low-Power-Stromwandler bieten zahlreiche Vorteile gegenüber konventionellen Wandlern. Sie müssen z.B. während der Installation oder Servicearbeiten nicht kurzgeschlossen werden, wodurch die Wandlertrennklemmen entfallen. Dadurch sparen Sie im Schaltschrank eine Menge Platz und die Kosten für die Trennklemmen sowie deren Installation.
Diese Low-Power Stromwandler sind kompatibel mit:
· Erweiterungsmodul 800-CT8-LP in Kombination mit dem UMG 801
· Netzanalysator UMG 96-PQ-L-LP
UMG 96-PQ-L-LP-CH 90...277 V AC, 90...250 V DC
Product description
