1500VA 2000VA 3000VA High Power Toroidal Transformer For Solar Inverter And UPS

The T180 Toroidal Transformer is an ultra-heavy-duty magnetic component engineered for high-power energy conversion and distribution systems. Utilizing a standardized T180 seamless ring core (typically 180mm outer diameter), this series is designed to handle substantial power loads ranging from 1500VA to over 3000VA (3kVA). It serves as a reliable power foundation for mission-critical equipment, offering the extreme efficiency and silent operation required by medical-grade isolators, high-wattage industrial inverters, and premium audio amplification stages.

• High-Grade CRGO Core: Constructed with premium Cold-Rolled Grain-Oriented (CRGO) silicon steel ribbons, wound into a continuous, jointless ring to eliminate air gaps and maximize magnetic flux density.
• 100% Electrolytic Copper Winding: Features heavy-gauge, high-purity copper wire distributed uniformly over the entire circumference, ensuring minimal DC resistance (DCR) and superior thermal management.
• Reinforced Insulation System: Primary and secondary windings are separated by multi-layer reinforced insulation, capable of sustaining isolation voltages up to 4500V AC, meeting international safety standards.
• Low Vertical Profile: Despite its massive power rating, the toroidal donut shape maintains a lower profile than traditional EI-laminated transformers, facilitating compact integration into 3U/4U rack enclosures.
• Optional Thermal Management: Can be equipped with auto-reset thermal switches or embedded NTC sensors to monitor internal winding temperatures in real-time.

• Renewable Energy Systems: The core component for 2kVA-3kVA solar inverters and bidirectional energy storage converters.
• Medical Isolation Rooms: Provides the "Galvanic Isolation" required for hospital-grade power supplies to protect sensitive diagnostic equipment from grid noise.
• Industrial UPS & Power Conditioners: Ensures stable voltage regulation for entire server racks or automated factory production lines.
• High-Power PA Systems: Delivers the massive instantaneous current required by professional concert amplifiers and stadium sound systems.

• Silent Industrial Operation: The lack of loose laminations and the vacuum-impregnated resin process virtually eliminate mechanical "magnetostriction" humming, ensuring a silent environment even at full 3kVA load.
• Extreme EMI Shielding: The inherent self-shielding properties of the toroidal ring drastically reduce stray magnetic fields, preventing interference with adjacent sensitive analog or digital traces.
• Significant Weight Reduction: Toroidal technology allows for a 45% reduction in weight compared to EI-frame transformers of the same kVA rating, leading to substantial savings in logistics and structural support costs.
• Complete Mounting Hardware: Every T180 unit is supplied with a heavy-duty steel pressure plate, reinforced neoprene cushions, and a high-tensile center bolt for secure, vibration-resistant mounting.
