Product Q&A
Q:What specifications are needed for production?
A:
Please provide Input Voltage, Output Voltage & Current, Rated Power (VA/W), Frequency (50Hz/60Hz), Construction type (Toroidal/EI/R), Installation method, and Insulation Grade.
Q:What is the difference between Toroidal and EI transformers?
A:
Toroidal offers high efficiency, low leakage, and low interference but is larger and costlier. EI is smaller, lighter, cheaper, and easier to maintain, suitable for general industrial use.
Q:What is the purpose of a shielding layer?
A:
A copper foil shielding layer between primary and secondary coils suppresses high interference, enhancing EMI resistance, essential for audio and measuring instruments.
Q:How do you ensure quality and service life?
A:
We use high-grade materials, VPI process, and conduct 100% factory tests including Hi-Pot, inter-winding, load, and no-load current tests.
Q:What is the MOQ and how is pricing determined?
A:
MOQ depends on customization (100pcs for standard, 500-1000pcs for custom). Price increases with power, material complexity, and process difficulty.
