1. "XX" Is Input Voltage: 03 = 3.3Vdc, 05 = 5Vdc, 09 = 9Vdc, 12 = 12Vdc, 15 = 15Vdc, 24 = 24Vdc, 48 = 48Vdc.
2. Over 48Vdc input voltage, using the 2nd package.
3. The input voltage increases, there will be an increase in efficiency.
4. No suffix is standard isolation (1KVDC) e.g, 14D-05S05NNL, 14D-05S05N2NL
*add suffix / 1.5KV for 1.5KVDC isolation, e.g, 14D-05S05N1.5KV, 14D-05S05N21.5KV
