50W Single Output Switching Power Supply 

## **Function Description** 

## **1.B+,B-** 

Connect the battery : B+ connected to battery positive. B- connected to battery negative. 

## **2.L** 

Output voltage detection, detect output voltage or battery voltage ( if battery is used). Voltage of L Pin AC OK Output voltage +0.2~0.7V(depends on Vf of diode) AC Fail 0V 

**3.+V,-V** Output voltage. Can't connect the battery. 

**4.CN2** Temperature sensor can be connected to the unit to allow temperature compensation of the charging voltage. If the sensor is not used, the charger still works normally. 

Reference example: (Under rated DC output voltage) Connect 100KΩ Thermistor(THINKING) on NTC.  The output voltage will change along with the temperature change. If the output voltage is adjusted other than the rated value by internal potential meter, please consult Meanwell for suitable value of Thermistor.

About Novapart

Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
