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. **==> picture [270 x 200] intentionally omitted <==** **----- Start of picture text -----**
