Ideal For
Not Recommended For
For this power transformer, ground the secondary winding at one point. Follow IEC 60076 terminal markings: primary terminals are typically H1/H2, secondary terminals are X1/X2. Ensure proper fusing on the secondary side. Never operate with secondary short-circuited unless designed for that duty. Verify polarity and phase relationships before energizing.
