The PQ6035 Series High-Frequency Transformer represents the pinnacle of high-kilowatt power conversion technology, specifically engineered for applications that demand extreme power density, unwavering stability, and superior environmental resilience. The "PQ" (Power Quality) core geometry provides maximum magnetic cross-sectional area and winding window within a standardized footprint, making it ideal for high-power switching mode power supplies (SMPS) operating in the 1.0kW to 3.5kW range.
This specific model features a unique Full-Metal Enclosure and Encapsulated Design, sealed within a high-grade aluminum or stainless-steel housing and filled with specialized high-thermal-conductivity epoxy resin under high-vacuum environment for maximum durability in harsh industrial conditions.

The power capability of up to 3.5kW is achieved through the massive magnetic cross-sectional area of the 6035 core, preventing flux saturation during current surges. Leakage inductance control of <1% ensures energy is transferred rather than stored, enabling higher efficiency and lower electrical stress on switching semiconductors.
The dielectric strength of 4500V AC provides an impenetrable safety barrier between high-voltage input and user-accessible secondary circuits. Combined with Class H (180°C) insulation rating and vacuum varnish, the internal copper windings withstand intense thermal cycles without degradation.
The outer metal shell serves as a primary thermal interface, allowing direct mounting onto cold plates or chassis to significantly reduce operating temperatures and achieve high power density in compact footprints.
Vacuum cycles remove air pockets and moisture from winding layers, followed by pressure injection of high-grade dielectric resin that bonds core, copper windings, and housing into a solid-state monolithic block for immunity to humidity and corrosive gases.
Oversized secondary leads made of multi-strand Litz wire combat skin and proximity effects at high frequencies, keeping AC resistance low and efficiency high with professional strain relief and heat-shrink insulation.
Precision-ground cores ensure mating surface flatness within microns, minimizing fringing effects and ensuring stable primary inductance for simplified controller loop compensation.
Critical component in DC Fast Charging (DCFC) stations and high-power On-Board Chargers (OBC) for electric buses and heavy-duty trucks, supporting 800V architectures and megawatt-level charging requirements.
Provides stable power for high-wattage Solar Inverters and Battery Energy Storage Systems (BESS), operating reliably in unconditioned outdoor cabinets with extreme temperature swings and high humidity.
Supports high-capacity motor drives, plasma cutting power supplies, and high-wattage server power units with robust isolation and metallic shielding for clean power in harsh electromagnetic environments.
