Product Description

1. Features
The fully-encapsulated printed circuit board is able to be directly welded and assembled, making it easy to use with a perfect outline.
It is compact in structure, solid, vibration-proof, moisture-proof, flame-resistant, and has high dielectric strength.
It has low idle current, high power factor, and good over input voltage capacity.
Compared with the T Series, it has higher reliability and better adaptability to the environment.
It has a built-in temperature protector, making it safer to use.
