CPS-H32524
Product Introduction
The ADLINK cPS-H325/24 is a 250 W DC power module designed for 3U CompactPCI systems requiring hot-swap power replacement and redundant power architecture. It accepts an 18–36 VDC input and connects to the system through a PICMG 2.11-compliant 47-pin power interface.
The module uses internal OR-ing diodes to support N+1 redundancy, allowing compatible systems to maintain power through a redundant supply arrangement. Active power factor correction is also included. The 8HP form factor makes rack compatibility and connector alignment important during replacement.
Application Scenarios & Field Pitfalls
Typical applications
- Industrial CompactPCI systems: Provides DC power to compatible embedded computing and control racks.
- Railway control equipment: Suitable for supported CompactPCI architectures used in transportation systems.
- Industrial data acquisition: Supplies compatible CompactPCI CPU, I/O, and communication modules.
- Redundant computing platforms: Supports N+1 power configurations where the backplane and system power design provide the required redundancy.
Field checks before replacement
- Verify the input supply. The
/24version is specified for 18–36 VDC. Do not substitute an AC-input or different DC-input variant. - Check the mechanical format. Confirm 3U CompactPCI and 8HP compatibility with the installed chassis.
- Inspect the 47-pin connector. Verify connector condition, pin alignment, and backplane compatibility.
- Check redundancy architecture. Confirm that the system supports N+1 operation and that the parallel supply arrangement is correctly configured.
- Verify the power budget. The 250 W rating is the module’s stated output capacity; calculate actual load demand and startup current before installation.
- Test hot-swap behavior. Follow the chassis manufacturer’s replacement procedure. Do not assume every CompactPCI backplane supports live removal simply because the module is hot-swappable.

Procurement and Replacement Notes
When ordering, provide the complete marking cPS-H325/24, not just CPS-H32524. Request photographs of the rating label, connector, and revision markings.
For incoming inspection, verify the 18–36 VDC input range, 250 W output rating, connector condition, and power-up behavior under a controlled load. In redundant installations, test the module together with the remaining power supplies to confirm proper load sharing and redundancy operation.
