Autotransformer
ESP 400/10
Characteristics
General data
Spartransformatoren der Baureihe ESP dienen zur Spannungsanpassung ohne Anforderungen an eine galvanische Trennung. Das einzigartige Vakuumimprägnierverfahren BLOCK IMPEX schützt die Transformatoren bestens gegen äußere Einflüsse bei verringerter Geräuschentwicklung. Die robuste Metallfußplatte mit Langlöchern sorgt für eine einfache und sichere Befestigung.
Benefits
› Autotransformer according to EN (IEC) 61558-2-13
› Significantly lower weight and smaller design compared to other transformer types with separate windings
