SILICON CORE, E + E, TRANSFORMER 400 VA, P/N 10139L2

The silicon core, E + E, 400 VA 3-phase 1000 Hz transformer (P/N 10139L2) delivers precise, reliable high-frequency power for industrial equipment, test systems, and specialized 3-phase applications. Specifically, its primary voltage is 170 VAC line-to-line in a Wye configuration, drawing 1.35 A, while the secondary provides 25 VAC line-to-line at 9.5 A, ensuring stable low-voltage output for sensitive circuits. In addition, copper windings minimize energy loss, and the laminated ferrite core enhances magnetic performance while reducing leakage flux. Furthermore, measuring 5” W × 5” D × 3” H, the transformer fits into tight spaces, with solder-lug primary and J-lug secondary terminations for easy integration. Therefore, it combines compact size, high efficiency, and durability to deliver dependable 1000 Hz power for professional engineers.
