Product Overview

KV Electronics Power and Isolation Transformers are built with high-quality EI/UI laminated silicon steel cores, designed specifically for robust low-frequency power conversion and mains isolation. Engineered for 220–240V AC applications, these transformers feature reinforced isolation layers using premium Mylar, PET, or Nomex materials to ensure superior dielectric strength and safety compliance.

Advanced winding techniques, including bifilar and parallel configurations, are utilized to optimize efficiency and minimize losses. The laminated core construction delivers low magnetizing current and excellent voltage regulation across the full load range.
