cPCI 3U DC 250W
The cPCI 3U DC 250W is a CompactPCI (cPCI) power supply module for DC-input operation, delivering up to 250 W in a 3U form factor with 8HP width, including hot-swap, redundancy support & current share bus, fully compliant with PICMG power supply standards
- Hot-swap capable, redundancy and current share support
- Wide DC input (18–36 VDC)
- Four output rails with significant current on +5 V and +3.3 V
- Minimum load requirement on +5 V (2 A)
- Efficiency ~74–77 % typical
Product Information
The cPCI 3U DC 250W module provides a compact, robust DC power supply solution for CompactPCI systems in demanding industrial, telecom or defence applications. With a wide input voltage range of 18-36 VDC, it is suitable for many DC-bus environments. Its strong output rails, hot-swap and redundancy capabilities, combined with a bi-colour status LED, make it ideal for high-availability systems requiring modular power components.
