Product Description

1.Features:
 The transformers have fully-encapsulated printed circuit boards that can be directly welded and assembled, making them easy to use with a perfect outline.
 They have a compact and solid structure that is vibration-proof, moisture-proof, flame-resistant, and has high dielectric strength.
 The transformers allow for different input and output configurations by changing the connection method.
 They have low idle current, high power factor, good capacity to withstand over input voltage, and are strong in EMC.
 A built-in temperature protector makes them safer to use.
