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.
