DIMENSION 159*97*38mm (L*W*H) MIL-HDBK-217F (25℃) PACKING 0.5Kg; 30pcs/16Kg/1CUFT 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. Line regulation is measured from low line to high line at rated load. 5. Load regulation is measured from 0% to 100% rated load. 6. 33% Duty cycle maximum within every 15 seconds. Average output power should not exceed the rated power. 7. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

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.
