Why Your Current Wiring Plans Are Holding Back Production
- Unclear schematics cause re‑work. 42% of OEM projects report at least one wiring error in the first prototype stage.
- High‑price components. Generic diagrams force you to over‑specify, inflating BOM by 18% on average.
- Compliance gaps. Missing CE/UL references lead to costly certification delays.
- Long lead‑times. Inadequate connection details stall assembly lines, adding up to 12 weeks per batch.
- Limited customization. Off‑the‑shelf diagrams rarely match your unique voltage‑current requirements.

Frequently Asked Questions
What information do I need to provide for a custom transformer connection diagram?
Please send the voltage, current, frequency, winding ratio, and any special grounding or safety requirements. Our engineers will deliver a PDF/STEP file within 48 h.
Can the diagrams be integrated directly into our PCB design software?
Yes. We provide both PDF and native CAD formats (Altium, Eagle, KiCad) that include layer‑specific netlists.

Do you offer volume discounts for large‑scale orders?
Discounts start at 5% for orders over 10,000 units and can reach 20% for 100,000+ units, plus free engineering support.
What are the standard payment terms?
We accept T/T, L/C, PayPal, and major credit cards. For first‑time customers, a 30 % deposit secures the design work.
How fast can you ship finished transformers after the diagram is approved?
Our high‑speed delivery network can dispatch from our 5,000 ㎡ factory within 7 business days for stocked models; custom builds ship in 14‑21 days.
