Three-Phase Isolation Transformer – 40 kVA (Copper Windings, K-Factor 4, Dyn11)

is a robust isolation transformer designed for reliable performance in industrial and medical applications. Its copper windings and K-Factor 4 construction effectively minimize harmonic currents, while the Dyn11 vector group ensures excellent phase balance and low leakage reactance. With a continuous rating of 40 kVA and efficiency exceeding 96%, this transformer is built to operate in ambient temperatures up to 50 °C. Users can select the IP00 open-frame version for controlled environments or the IP23 enclosed version for protection against dust and moisture. Compliant with IEC 61558-1, IEC 61558-2-4, IEC 60076-1, and IEC 60601-1 standards, it provides essential galvanic isolation and adheres to strict safety regulations. 🔧 Specifications:
