Note:
1: No suffix is standard isolation (1.5KVDC) e.g., EC4-05S05
*add suffix “3” for 3KVDC isolation
2: No “P” suffix = no short circuit protection, e.g., EC4-05S05
*add suffix “P” for short circuit protection, e.g., EC4-05S05P, EC4-05S12P3
3: Character after “-“ is Input Voltage: 12=12Vdc, 15=15Vdc, 24=24Vdc
e.g., EC4-12S05P, EC4-15S12P3, EC4-24S15P.
