Product Q&A

Q:What specifications are needed for a 220V to 12V transformer?

Please provide Input Voltage with fluctuation range, Output Voltage and Current, Rated Power (VA/W), Frequency (50Hz/60Hz), Construction type (Toroidal/EI/R), Installation method, and Insulation Grade.

Q:Which should I choose: Toroidal or EI transformer?

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?

Yes, a copper foil shielding layer can be added between primary and secondary coils to suppress high interference and enhance EMI resistance.

Q:How do you ensure quality and service life?

We use high-grade silicon steel and pure copper, apply VPI process, and conduct 100% testing including Hi-Pot, inter-winding, and load tests.

Q:What is the price and MOQ?

Price depends on power and complexity. MOQ is lower for standard specs (e.g., 100pcs) and higher for custom molds (e.g., 500-1000pcs). Larger quantities reduce unit price.
