Ripple & Noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1 uf & 47 uf parallel capacitor.
Features: 1. Low price and high reliability 2. AC input range selected by Switch 3. Protections:Short circuit/Over load/Over voltage 4. High efficiency and Long life 5. Soft-start current can reduce the AC input impact effectively
