Product Overview
Our 3KVA Single Phase Voltage Transformer is a high-performance, energy-efficient power solution engineered for global industrial applications, catering to factory power systems, electrical engineers, CNC machine tools, photovoltaic (PV) systems, power transmission equipment, precision instruments, generators, and EV charging stations. Manufactured by SHLEIPUSI in Shanghai, China, this transformer delivers reliable full-capacity operation with an optimized design for low temperature rise, ultra-low energy losses, and long service life. Built with a high-permeability core and fully compliant with global environmental protection standards, it meets the rigorous power demands of the electrical and industrial sectors worldwide.
Key Features & Advantages
This 3KVA single phase voltage transformer integrates industry-leading design and premium materials for unmatched performance:
- High-Efficiency Energy-Saving Design: New high-permeability silicon steel core enables noise-free (<55dB) operation, high magnetic flux, and minimal energy loss; high-purity winding material ensures exceptional electrical conductivity, low temperature rise (<80K), and stable full-capacity output, with ≥90% working efficiency.
- Superior Safety & Insulation: High-grade insulation materials withstand 3500V dielectric strength tests, paired with a high-quality nylon frame for outstanding insulation performance. Reinforced terminals with robust insulation properties guarantee safe, durable operation in harsh industrial environments.
- User-Friendly Reliable Construction: Convenient wire connection design enables fast installation, with no additional waveform distortion to protect sensitive precision equipment. Boasting F-class insulation, ±2% output precision, and 4% short-circuit resistance, it adapts to a wide operating temperature range of -10℃ to +45℃.
