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, detection output voltage or battery voltage ( if battery is used). L=output voltage +0.7 -0 V. 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: Connect 100K Thermistor(THINKING) on NTC. Adjust VR to cause the output voltage is normally voltage. The output voltage will change along with the temperature change.
