High Power Low Noise E250 Three Phase Transformer Stable Efficient For Machinery
Stable and efficient three-phase laminated power transformer designed for industrial machinery applications.
Product Overview
The E250 Custom Transformer is a three-phase laminated power transformer designed for voltage conversion, electrical isolation, auxiliary power, and industrial power distribution at 50 Hz or 60 Hz.
The product shown uses three separate phase windings installed on a common laminated magnetic core. Heavy steel clamping channels and a bolted open-frame structure provide mechanical support and chassis-mounting points.
Available Configurations
Three-phase isolation transformer
Three-phase step-down transformer
Three-phase step-up transformer
Three-phase control transformer
Three-phase rectifier transformer
Three-phase autotransformer
Multiple-secondary transformer
Delta-to-star transformer
Star-to-delta transformer
Customer-defined phase-shifting transformer

Frequently Asked Questions
Q1: Is E250 a fixed kVA rating?
No. E250 identifies the magnetic and mechanical platform. Actual capacity depends on core stack, conductor size, voltage, frequency, impedance, insulation class, cooling, and allowable temperature rise.
Q3: Can primary and secondary voltages be customized?
Yes. Input, output, and tap voltages can be designed according to the required electrical system.
Q4: Can the transformer be designed for both 50 Hz and 60 Hz?
Yes, if the core and windings are specifically designed for both frequencies. A transformer designed only for 60 Hz must not automatically be operated at 50 Hz.
Q5: What is the MOQ?
The MOQ shown for this E250 product is one piece. Final prototype and production quantities depend on materials, construction, and project requirements.
