NOTE:
1. Short JP1 to connect +S and +Vo, JP2 to connect –S and –Vo with local sense.
2. Remove jumper( JP1& JP2),terminal block port +S,-S & Trim can be used to Output Remote Sensing or Output
Voltage Adjustment functional(see application note).
3. Thermal resistance is referenced to the application note.
4. Include TVS for input surge voltage protection.
5. Recommend external fuse for input reverse polarity protection (Include shunt diode inside).
