Ripple & Noise are measured at 20MHz of bandwidth with ceramic 0.1uF & chemi-con KY 47uF parallel capacitor. A 30cm twisted pair of no.18 AWG copper wire is connected to a 47uF and 0.1uF capacitor of proper polarity and voltage rating. The oscilloscope probe ground led should connect right to the ground ring of the probe and be as short as possible. The oscilloscope bandwidth should be at 20MHz and connected to AC ground. 2. Hold-up Time measured at 90% Vout. 3. Please check the derating curve for more details. 4. Main Vout >3% Load, 12V (Aux) / 0.3A., 12V (Aux) need 0.1A Minimum Load, Auxiliary voltage output ground 10.2~13.3V 5. Strongly recommend to conduct this test with DC Voltage. If customer wishes to test with AC Voltage, please disconnect all Y-Capacitors from Digital Power power supply. 6. Current Share Board (Optional): (a.)The output voltage difference of each parallel single element should be less than 0.2V. (b.)Output power at parallel operation = rated power per unit x number of unit x 90% (c.)Connect in parallel no more than 2 units. Please contact Digital Power for advice if more than HDM500 HDM500 2 is needed. (d.)Minimum Load Should be 15%. 7. CAUTION: Double pole, neutral fusing.
