Product Description

1.  Features
The fully-encapsulated printed circuit board can be directly welded and assembled, and has a perfect outline.
It has a low mounting height, compact structure, and is solid, vibration-proof, moisture-proof, flame-resistant, and has high insulation withstand voltages.;
It is easy to use and reconfigure, and alternative input/output voltages can be obtained by changing the connections of the primary and/or secondary.
It has a built-in temperature protector, making it safer to use.
