Product Description
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
Application Specifications
The following values represent common project-discussion ranges used by international buyers when evaluating an E250 three-phase laminated power transformer.
| Industry | Typical Application | Primary Voltage | Secondary Voltage | Capacity Range |
|---|---|---|---|---|
| Industrial Control Cabinets | Main isolation, control power, PLC supply, contactor circuits | 380-480 VAC | 24-400 VAC | 1-30 kVA |
| Industrial Machinery | CNC machines, pumps, compressors, packaging lines | 380-480 VAC | 200-415 VAC | 2-30 kVA |
| Motor Drives and VFD Systems | Input isolation, drive supply, harmonic mitigation | 380-600 VAC | 200-480 VAC | 3-50 kVA |
| UPS and Data Center | Input isolation, bypass supply, voltage conversion | 380-480 VAC | 208-415 VAC | 3-50 kVA |
| Solar and Energy Storage | Inverter input/output isolation, PCS auxiliary distribution | 380-600 VAC | 208-415 VAC | 3-50 kVA |
| EV Charging Equipment | Input isolation, voltage conversion, charger cabinet supply | 380-480 VAC | 208-480 VAC | 3-50 kVA |
All values above are typical buyer inquiry references. Final ratings must be confirmed through the approved customer specification drawing and sample-validation process.

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.
Q2: What information is required for quotation?
Primary voltage, secondary voltage, rated kVA, frequency, vector group, voltage taps, impedance, load type, duty cycle, insulation class, temperature-rise limit, terminals, mounting dimensions, and applicable standard.
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.
