Product Q&A

Q:What specifications are needed for a custom transformer?

Please provide input/output voltage and current, rated power (VA/W), frequency (50Hz/60Hz), construction type (EI/Toroidal), installation method, and insulation grade.

Q:Should I choose a Toroidal or EI transformer?

Toroidal offers higher efficiency and less interference but is costlier. EI transformers are more cost-effective, lighter, and easier to maintain for general industrial use.

Q:Do transformers have a shielding layer?

Yes, a copper foil shielding layer can be added between coils to suppress high-frequency interference and enhance EMI resistance, essential for audio and measuring instruments.

Q:How do you ensure transformer quality and lifespan?

We use high-grade silicon steel and pure copper, apply vacuum impregnation for moisture resistance, and conduct 100% factory tests including Hi-Pot and load tests.

Q:What is the price and MOQ?

Price and MOQ depend on specifications. Standard specs may have an MOQ of 100pcs, while full customization may require 500-1000pcs due to mold and sampling costs.
