Product Q&A
Q:What specifications are needed for production?
A:
Please provide Input Voltage (e.g., AC 220V), Output Voltage/Current, Rated Power (VA/W), Frequency (50Hz/60Hz), Construction type (Toroidal/EI), Installation method, and Insulation Grade.
Q:Which should I choose: Toroidal or EI transformer?
A:
Toroidal offers higher efficiency, less leakage, and smaller size but is costlier. EI is lower cost, easier to maintain, and suitable for general industrial use.
Q:What is the minimum order quantity?
A:
The minimum order quantity is 2000 pieces.
Q:What are the payment terms?
A:
Payment terms are T/T (Telegraphic Transfer).
