Product Description
Pulse Transformers IT series with double secondary winding
The Pulse Transformers IT series with double secondary winding offer galvanic separation between drive and power circuits, providing voltage resistance up to 4 kV and ignition currents up to 1 A. With turns ratios up to 3:1:1, these transformers are ideal for various switching applications, power supplies, and high-speed data transmission. Key advantages include robust galvanic isolation, high voltage withstand capability, and very low partial discharge effects, all housed in a vacuum-potted construction for enhanced reliability. Custom-specific versions are available upon request.
