Safety isolating transformer
EVKE 250/24
Characteristics
General data
Sicherheitstransformatoren der Baureihe EVKE dienen der sicheren galvanischen Trennung des Primärstromkreises vom Sekundärstromkreises und wurden nach EN (IEC) 61558-2-6 gefertigt. Durch die Begrenzung der Ausgangsspannung sind die Transformatoren für den Aufbau von SELV und PELV Stromkreisen geeignet.
Benefits
› Integrated short-circuit and overload protection
› Excellent moisture protection and low noise emission thanks to XtraDenseFill resin encapsulation
› Very high protection class
› Plastic screw connections on terminals
