Test Procedure for the CCRACGEVB Evaluation Board CAUTION: VERY HIGH VOLTAGE. MAY CAUSE SEVERE INJURY OR DEATH. Test Equipment Required: 1. Adjustable, isolated AC power source capable of providing a range of 0 to 120 Vac. 2. Two or more digital multi-meters to measure the output current and load voltage. 3. Dimmer light switch. Setup: (Figure 1) 1. Connect AC power source across VIN1 and VIN2. Polarity does not matter. 2. Connect a voltmeter across TP10(+) and TP11(-) to measure voltage across R14 in mVDC (1mV = 1mA). This will be the LED current measurement. 3. Connect a voltmeter across TP9(+) and TP10(-) to measure the LED Voltage in VDC. 4. Remove any jumpers that may be on the board. 5. Always be sure that the voltage is off before changing jumpers. Figure 1: Setup for Circuits 1, 2, and 3. 3/8/2013 1 www.onsemi.com Circuit 1: Testing CCRs 1. 2. 3. 4.
