1. Product Overview: FEC30 Series Power Modules

️· Description: These are DC-DC power modules.
️· Compliance: Designed to meet EN55022 Class A with external capacitors. EN61000-4-4 and EN61000-4-5 require an external input filter.
️· Derating: Performance derating curves are included for the 48V models.
️· Heatsink: An optional heatsink (P/N: 7G-0011C-F) is available.

2. Input Voltage Ranges and Models

The FEC30 series comes in three input voltage ranges:

️· 12xxx: 12V input
️· 24xxx: 24V input
️· 48xxx: 48V input
