Frequently Asked Questions

Q: What makes the ETD type transformer superior for high-frequency applications?

The ETD type features a circular center column and a large window area, which reduces leakage inductance and improves heat dissipation, critical for high-frequency stability.

Q: Can these transformers be used in Electric Vehicle (EV) charging systems?

Yes, our ETD series is specifically designed for EV chargers, providing the high power density and thermal efficiency required for fast-charging infrastructure.

Q: Do you offer customized winding specifications for specific frequencies?

Absolutely. We provide ODM design services where we customize the current, frequency, and size of the transformer to meet your exact circuit requirements.

Q: How does the "smooth winding" feature benefit the end product?

Smooth winding ensures a more uniform distribution of the conductor, which reduces hotspots and minimizes the risk of insulation breakdown over time.

Q: What is the typical lead time for bulk OEM orders?

Lead times vary by model (ETD29-ETD42) and volume. Please contact our sales team with your technical drawings for a precise production schedule.

Q: Which ETD model is best for Photovoltaic (PV) Inverters?

Depending on the power output, models like ETD39 and ETD42 are often preferred for PV inverters due to their superior power density and heat management.
