FAQ:1. Are you factory? Yes, we have more than 17 years production experience.2. All goods are tested before shipment?Yes of course, all goods are tested with different testing machines for different electrical parameter.3. Small Order Quantity is available?Yes of course we can. In our history, the smallest order is 5 pcs. For your reference, small quantity means higher prices.4. Protection of goods is ok for rough handling during transformer from China to your warehouse?Yes, we have done sound protection measurements for protection.5. How to be in compliance with UL insulation system?We use all the materials which is in compliance with UL certification.6. VDE certification is available?We can do that once you do need it.7. Small Size Toroidal transformer (inside is about 10mm) is available?Yes, we have reliable ability to hand wind such small size transformer. But the time of shipment is normal.
