### 4. Functionality

The cPS‑175R/48 operates as a modular DC power supply for CompactPCI systems. It converts a 48 V DC input into regulated low‑voltage DC outputs required by CompactPCI backplanes and peripheral modules.

Operation Principle:
- The unit plugs into a 47‑pin CompactPCI power connector on the backplane (Positronic PCI47M400A1).
- It provides isolated, regulated outputs for system logic (+3.3 V, +5 V) and auxiliary rails (+12 V, −12 V).
- In redundant configurations, two or more units share load current via dedicated share lines (V1 SHARE, V2 SHARE).
- Hot‑swap capability allows insertion/removal under power without system interruption.
- Control signals (EN#, INH#, DEG#, FAL#) manage enable, inhibit, derating, and fault reporting functions.

Typical Applications:
- Industrial CompactPCI controllers and I/O systems
- Telecommunications and networking equipment (−48 V DC environments)
- Embedded computing platforms requiring high availability
- Redundant power architectures in automation or defense systems
