CompactPCI (cPCI) Series: Comprehensive Module Range and Technical Overview

The CompactPCI (cPCI) standard, defined by the PICMG 2.0 specification, is a high-availability industrial computing architecture deployed across critical infrastructure sectors including chemical processing plants, nuclear power stations, petroleum refineries, railway signaling systems, and defense electronics. The CPCI-350 and CPCI-354-1203 power supply modules represent the backbone of cPCI chassis power distribution, delivering regulated DC outputs to backplane-mounted processor, I/O, and communication modules in 3U and 6U form factors. These units conform to the IEEE 1101.10 mechanical standard and the PICMG 2.11 power interface specification, ensuring interoperability across multi-vendor cPCI ecosystems. Their deployment in redundant N+1 power configurations makes them a long-term maintenance-critical component in installations with operational lifespans exceeding 15–20 years.

The Evolution of CompactPCI Architecture

CompactPCI emerged in 1994 as an industrial adaptation of the PCI bus standard, replacing VMEbus in many telecom and process-control applications. The original PICMG 2.0 (32-bit, 33 MHz) specification supported up to 8 slots per segment. Subsequent revisions introduced 64-bit/66 MHz operation (PICMG 2.0 R3.0), hot-swap capability (PICMG 2.1), and system management interfaces (PICMG 2.6). The power supply specification evolved in parallel: early cPCI PSUs delivered a single +5 V / +3.3 V rail; later designs such as the CPCI-350 series added +12 V and −12 V auxiliary rails to support modern processor boards and high-speed serial transceivers. The CPCI-354-1203 variant introduced a 120 W continuous output rating with active power factor correction (PFC), addressing harmonic distortion requirements in CE-marked installations. As the platform matured into the 2010s, PCI Express-based derivatives (CompactPCI Serial / PICMG CPCI-S.0) began displacing parallel-bus cPCI in new designs, while the installed base of legacy parallel cPCI systems—including those powered by the CPCI-350 family—remained in service, creating sustained demand for compatible replacement power supplies and spare modules.

Sourcing Hard-to-Find & Obsolete CompactPCI Parts

The parallel CompactPCI platform entered end-of-life status with most original equipment manufacturers between 2015 and 2022. Chassis integrators and plant maintenance teams operating legacy cPCI systems face a common challenge: OEM discontinuation of power supply modules such as the CPCI-350 and CPCI-354-1203 while the host system remains in active service with no approved migration path. DriveKNMS maintains a dedicated inventory of new-old-stock (NOS), refurbished, and functionally equivalent replacement units for the CompactPCI power supply range. Our sourcing network spans authorized distributor overstock, decommissioned system teardowns, and manufacturer-certified repair channels across Europe and Asia. For end-users requiring long-term supply agreements (LTA) covering 3–10 year maintenance windows, DriveKNMS provides contractual stock reservation and condition-graded inventory with full traceability documentation. All units are shipped with a certificate of conformance and, where applicable, original manufacturer test reports.

Quality Control for the CompactPCI Range

CompactPCI power supply modules present specific test challenges due to their backplane-coupled output architecture and hot-swap inrush current management circuits. DriveKNMS applies the following verification protocol to all CPCI-350 and CPCI-354-1203 units prior to dispatch:

• Backplane load simulation: Each PSU is tested under a programmable electronic load replicating a fully populated 8-slot cPCI chassis at 80%, 100%, and 110% rated output.
• Hot-swap inrush test: Inrush current is measured and verified against PICMG 2.1 R2.0 limits using a calibrated current probe and oscilloscope capture.
• Rail regulation accuracy: All DC output rails (+5 V, +3.3 V, +12 V, −12 V) are verified to within ±1% of nominal under static and dynamic load conditions.
• Ripple and noise measurement: Output ripple is measured per JESD51 methodology; units exceeding 50 mV peak-to-peak on the +5 V rail are rejected.
• Thermal burn-in: Units are operated at full rated load for a minimum of 4 hours at 50 °C ambient to screen for early-life failures.
• Isolation and hi-pot test: Input-to-output isolation is verified at 1500 VAC for 1 minute per IEC 60950-1 requirements.
