Product Q&A
Q:What specifications are needed for a 220V to 12V step-down transformer?
A:
Please provide Input Voltage with fluctuation range, Output Voltage and Current, Rated Power (VA/W), Frequency (50Hz/60Hz), Construction type (Toroidal/EI/R-type), Installation method, and Insulation Grade.
Q:What is the difference between Toroidal and EI transformers?
A:
Toroidal transformers offer higher efficiency, less leakage magnetism, and smaller volume but are more expensive. EI transformers are lower cost, easier to maintain, and suitable for general industrial equipment.
Q:What is the purpose of a shielding layer in a transformer?
A:
A shielding layer (usually copper foil) between primary and secondary coils is grounded to suppress high interference, enhancing EMI resistance, which is essential for audio equipment and measuring instruments.
Q:How do you ensure transformer quality and lifespan?
A:
We use high-grade silicon steel, 100% pure copper, and Class B insulation. We apply vacuum impregnation (VPI) and conduct 100% factory tests including Hi-Pot, load, and no-load tests.
Q:What is the MOQ and how is pricing determined?
A:
MOQ depends on customization: ~100pcs for standard specs, 500-1000pcs for full custom. Price increases with power, material complexity, and process intricacy. Larger quantities lower the unit price.
