Bel Fuse 3PH Three-Phase Transformers
Bel Fuse 3PH Three-Phase Transformers are mechanically rigid transformer units, adaptable to multiple industrial, commercial, manufacturing, and medical requirements. The transformers feature a design configuration for three-phase DELTA input and WYE output, which provide greater current balance and a supply line neutral point. Bel Fuse 3PH Three-Phase Transformers offer a value-added electrostatic shield (ESS) between input/output windings, preventing undesirable signal feed-through. The 3PH series has a 4kVAC dielectric withstanding rating with a low leakage current capability, making it well suited for power conversion. The 3PH three-phase transformers are RoHS/REACH compliant and ideal for medical, industrial, lighting, electric vehicle (EV) charging, and green energy applications.
