Industrial 133 Shielded Drive Isolation Transformer

Hevi-Duty shielded drive isolation transformer, 11 kVA, provides isolated power for industrial drive systems while protecting sensitive controllers from line disturbances. The unit’s high-voltage side is 460 V in delta configuration, and the low-voltage side delivers 230 V in a Y configuration, with model designation 133. Shielded construction helps minimize electromagnetic interference between the mains supply and drive electronics. Delta-wound primary and Y-wound secondary configurations are common for systems that interface a 460 V three-phase supply with 230 V drive circuitry, enabling reliable operation and compatibility with typical industrial power distribution. With an 11 kVA rating, the transformer offers substantial capacity for mid-size drive loads without overloading, making it suitable for installations demanding robust isolation and durability.
