P12441: Thermoelectric Stove for Haiti 1 Fan Converter Test Procedure 1. Test Name: Fan Converter Test Author: Andrew and Xiaolong Battery provides different level of voltages when it’s at different battery level. A fan converter is used to convert various input voltages to 12V with current output of 100mA to run the fan correctly. 2. Required Equipment 1 2 3 4 Equipment Description Power supply Multimeter Fan (KD1204PFB2) Fan Converter Quantity 1 2 1 1 Settings 5V – 7V varied input voltages Current (A) and Voltage (V) Table 1: Required equipment and its settings. 3. Test Procedure Step 1: Connect the power supply to the input pins of the Fan converter, and the mulitmeter in series with the output pins of the Fan converter Step 2: Slowly increase the power supply voltage from 5V to 7V Step 3: Measure the output voltage and current of the Fan converter 4. Test Results Step # 2 4 6 Description Measure the output voltage and current of the fan converter with an input of 5V. Measure the output voltage and current of the fan converter with an input of 6V. Measure the output voltage and current of the fan converter with an input of 7V. Spec Measurement Vout: 12V +/- 10% Iout:.075A +/- 10% Vout:12.5V Iout:.082A Vout: 12V +/- 10% Iout:.075A +/- 10% Vout:11.75V Iout:.074A Vout: 12V +/- 10% Iout:.075A +/- 10% Vout:11.76V Iout:.074A Table 2: The results of the test procedure. 5. Pass/Fail Did the unit pass or fail the test? Defend your decision. PASS FAIL Pass Table 3: PASS/FAIL
