Note:
1: No suffix is standard isolation (1.5KVDC) e.g., EC3-15S05P
*add suffix “3” for 3KVDC isolation, e.g., EC3-12S05P3, EC3-15S12P3
Package style: no suffix = package 1, T = package 2, R = package 3
e.g., EC3T-12S05P, EC3R-24S12P3
2: No “P” suffix = no short circuit protection, e.g., EC3-05S05
*add suffix “P” for short circuit protection, e.g., EC3T-05S05P, EC3R-05S12P3
Temperature Derating Graph
3: Character after “-“ is Input Voltage: 12=12Vdc, 15=15Vdc, 24=24Vdc
e.g., EC3R-12S05P, EC3-15S12P3, EC3T-24S15P.
