1. fully enclosed printed circuit board directly welded installation, beautiful appearance; 2;

2. small installation height, compact structure, solid, anti-vibration, moisture-proof, flame retardant, high electrical strength;

3. easy to use, the same transformer can get different input and output combinations by changing the connection;

4. high efficiency, small magnetic leakage, good output characteristics, strong EMC capability;

5. built-in temperature protector, safer to use (M90, M110, M160 without temperature protection).
