Description
ADLINK cPS-H325/24 | 3U CompactPCI Redundant Power Supply
Dynamic Product Introduction
Mission-critical industrial, transit, and telecommunication systems built on 3U CompactPCI architectures require uninterrupted power delivery to safeguard system uptime. When a legacy rack power supply encounters input fluctuations or component degradation, installing a verified ADLINK cPS-H325/24 power module restores absolute electrical stability to the chassis.
Engineered strictly to PICMG 2.11 standards, this 250W hot-swappable unit features an active 18–36 VDC input range and internal OR-ing diodes for seamless N+1 redundant configurations. Deploying a fresh cPS-H325/24 module ensures reliable multi-rail voltage distribution, thermal resilience, and continuous operation in demanding environments.

Global Sourcing & Live-Test SOP (Transparency Core)
Acquiring legacy or surplus industrial power supplies through secondary markets requires an exhaustive verification workflow to guarantee component longevity and clean output regulation under load.
- Inbound Verification: Incoming cPS-H325/24 batches undergo high-magnification optical inspection of the 47-pin backplane connector, electrolytic filter capacitor health, and laser traceability tags against official ADLINK production logs.
- Live Simulation: Technicians slide the power module into a dedicated 3U CompactPCI test chassis energized by a variable DC source to verify soft-start behavior and pre-charge performance.
- Diagnostics: Engineers execute full-scale load tests across all DC output rails (+5V, +3.3V, +12V, -12V), verifying ripple voltage thresholds, fault signal (FAL#) triggers, and running a 24-hour thermal soak chamber test.
- Final Prep: Hardware units receive comprehensive revision logging, protective terminal capping, and vacuum sealing inside heavy-gauge moisture-barrier ESD shielding bags.
The Field Engineer’s Pitfall Guide
❗ Inadequate Subrack Airflow: Operating the cPS-H325/24 module at full load without maintaining minimum recommended chassis airflow (typically 20 CFM forced air) will trigger thermal protection shutdowns (+70°C OTP threshold).
❗ Hot-Swap Misalignment Force: Forcing the 8HP-wide module blindly into the subrack backplane can bend the delicate 47-pin male/female power blades. Always guide the unit smoothly along the chassis tracks before engaging the front latching mechanism.
❗ Input Voltage Transient Spags: While the module accommodates an 18–36 VDC window, severe upstream surges exceeding threshold limits without proper external transient protection can damage the primary switching transistors.
Intent-Driven FAQ
Will swapping this cPS-/24 module interrupt active system operations?
If your chassis is configured with an N+1 redundant power setup utilizing multiple modules, a healthy secondary supply will maintain system uptime while you hot-swap the faulted unit.
Are these units original factory sealed or surplus stock?
Sourced inventory pools span both original factory-sealed packaging and fully certified, tested surplus hardware. Every single unit undergoes rigorous bench validation under simulated loads prior to dispatch.
Can this power supply operate in standard AC chassis architectures?
No. The cPS-/24 is purpose-built for DC-powered environments, specifically requiring an 18–36 VDC input source. For AC mains, variant models like the cPS-/AC are utilized.
What status indicators are available on the front panel?
The front faceplate features integrated LED indicators, including a [POWER] light for valid input status and a [FAULT] indicator for critical internal conditions or rail failures.
What kind of warranty accompanies a replacement power module?
All supplied units carry a comprehensive 1-year operational warranty covering internal component health, switching stability, and output rail performance.
Are you installing this cPS-/24 power supply into an active industrial or transit CompactPCI rack, or keeping it on hand as a critical system hot-spare?
