NOTE
1. Ripple & Noise are measured at 20MHz of bandwidth with 0.1uF & 47uF parallel capacitor.
2. Hold-up Time measured at 90% Vout.
3. Main Vout must be >50% Load, 12V (Aux) / 0.5A.
4. Please check the derating curve for more details.
5. Strongly recommend to conduct this test with DC Voltage. If customer wishes to test with AC Voltage,
please disconnect all Y-Capacitors within Arch power supply.
