Product Q&A
Q:Which should I choose: Toroidal or EI transformer?
A:
Toroidal offers high efficiency and low interference but is larger and costlier. EI is smaller, lighter, cheaper, and easier to maintain, suitable for general industrial use.
Q:Is there a shielding layer in transformers?
A:
Yes, a copper foil shielding layer can be added between primary and secondary coils to suppress interference and enhance EMI resistance, essential for audio and measuring instruments.
Q:How do you ensure quality and service life?
A:
We use high-grade silicon steel and pure copper, apply vacuum impregnation (VPI), and conduct 100% factory tests including Hi-Pot, inter-winding, and load tests.
Q:What is the price and minimum order quantity (MOQ)?
A:
Price depends on specifications and quantity. MOQ is lower for standard specs (e.g., 100pcs) and higher for custom specs requiring mold opening (e.g., 500-1000pcs).
Q:How long does delivery take?
A:
Standard products take 10-15 working days. New customizations require an additional 5-7 days for samples. Large orders may take 15-30 days.
