SINGLE PHASE ISOLATION TRANSFORMER, 0.4 KVA, 400 HZ

This is a high-frequency, single-phase transformer designed for precision applications ranging from 1 kHz to 20 kHz. Rated at 2 kVA, it features robust copper windings with dual-coil construction on a 4 mil E + E silicon core, ensuring high efficiency and minimal core losses at high frequencies. The transformer is built with an open core and coil design, providing superior thermal management and reduced leakage inductance.

The primary side accepts 120 VAC sine wave input via braid connections measuring 1.25” x 10 MIL, while the secondary side delivers a high-voltage output of 10,610 VAC through #18 AWG high-voltage flexible leads. This transformer is ideal for applications requiring reliable performance at high frequencies, including test equipment, induction heating, and specialized high-voltage circuits.
