Signal Transformer / Bel EcoTran Isolation Transformers

Signal Transformer EcoTran Isolation Transformers utilize a split-bobbin construction for superior isolation with no exposed metallic surfaces. The Touch Safe terminal design of the EcoTran transformers eliminates potential shock hazards. This signal transformer series offers 105VA to 450VA ratings and 4kV dielectric strength. The components provide 115/230V and 50/60Hz primaries and dual secondary outputs for series or parallel connection. This transformer series also provides CE-compliant reinforced insulation and a leakage current of less than 30µA.
