High Light EI240 low frequency transformer ，Custom low frequency transformer ，Large 3 phase power transformer
Large Custom EI240 Low Frequency Transformer
Stable, durable transformer platform for industrial controls and automation systems
Product Overview
The EI240 is a large low-frequency laminated-core transformer platform designed for industrial control power, voltage conversion, galvanic isolation, auxiliary distribution, automation equipment, machinery, emergency-power systems, energy storage, and charging equipment.
Important Note: The values below are common international buyer inquiry references and starting points for engineering discussion. They are not fixed or guaranteed ratings. Final specifications are confirmed through the approved specification, drawing, and sample-validation process.

Frequently Asked Questions
Does EI240 define a fixed kVA rating?
No. Capacity depends on phase arrangement, stack size, lamination material, flux density, frequency, winding design, impedance, cooling, insulation, ambient temperature, and temperature rise.
Is the transformer single phase or three phase?
The image shows multiple coil sections and terminals, but the phase configuration cannot be confirmed from the image alone. Both configurations are available.
What information is required for quotation?
Provide phase count, input/output line voltage, vector group, neutral requirements, kVA, frequency, taps, impedance, load type, power factor, harmonics, duty cycle, temperature rise, insulation, cooling, dimensions, terminals, and test requirements.
Can voltages be customized?
Yes. Input voltage, output voltage, taps, neutral arrangement, multiple secondaries, and winding connections can all be customized.
Can it operate at both 50Hz and 60Hz?
A dual-frequency design may be developed, but it must be designed and validated for the lower frequency.
What is the MOQ?
Minimum order quantity is 100 pieces, subject to material availability, tooling, complexity, and qualification requirements.
Final Note: The EI240 model or lamination platform does not by itself define fixed phase arrangement, power, voltage, current, frequency, impedance, insulation, or thermal ratings. Final performance is confirmed only through the approved drawing, wiring diagram, electrical specification, material system, test plan, and customer sample-validation process.
