The TELKOR CPCI-AC-6U-400 is a high-reliability, 400-watt AC-input power supply module designed for 6U CompactPCI (CPCI) systems operating in demanding industrial, defense, and aerospace environments. Compliant with the PICMG 2.11 standard for CPCI power specifications, this 4HP-wide (0.8″ / 20.32 mm) module delivers stable, isolated DC outputs (+3.3V, +5V, +12V, –12V) directly to the CPCI backplane, supporting high-performance embedded computing blades such as single-board computers, FPGA processing cards, and I/O controllers.
Engineered for mission-critical applications, the CPCI-AC-6U-400 accepts a universal AC input range (90–264 VAC, 47–63 Hz), enabling global deployment without manual voltage selection. It features active power factor correction (PFC), overvoltage/overcurrent/short-circuit protection, and intelligent sequencing to ensure safe system startup. With conduction-cooled options available and robust mechanical construction meeting MIL-STD-810 shock/vibration requirements, the TELKOR CPCI-AC-6U-400 is widely deployed in radar signal processors, electronic warfare (EW) systems, mobile command centers, and automated test equipment (ATE).

Main Features and Advantages
✅ Universal AC Input & High Efficiency
The CPCI-AC-6U-400 operates from any standard mains supply worldwide (90–264 VAC), eliminating region-specific power configurations. Its active PFC and >85% efficiency reduce harmonic distortion and heat generation—critical for densely packed CPCI chassis.
✅ Full PICMG 2.11 Compliance
Designed strictly to the CompactPCI power specification, it ensures seamless interoperability with backplanes from Kontron, Elma, Schroff, and others. The module provides correct sequencing of +5V standby, main outputs, and Power Good signals per standard timing diagrams.
✅ Ruggedized for Harsh Environments
Built with conformal coating, reinforced connectors, and robust internal potting (in conduction-cooled versions), the CPCI-AC-6U-400 withstands extreme temperature swings, high humidity, and severe mechanical stress—ideal for airborne, shipboard, or field-deployed systems.
✅ Intelligent Protection & Monitoring
Integrated protections include overvoltage (OVP), overcurrent (OCP), short-circuit (SCP), and overtemperature (OTP). A front-panel LED indicates operational status, while the “Power Good” signal enables system-level fault management.
✅ Hot-Swap Ready for High Availability
Supports live insertion/removal in redundant or N+1 power architectures, minimizing downtime during maintenance—a key requirement in telecom and defense CPCI systems requiring 24/7 operation.

Installation and Maintenance
? Pre-Installation Checklist:
Verify CPCI chassis supports 4HP power slots and meets PICMG 2.11 backplane pinout.
Ensure adequate airflow (≥200 LFM) if using air-cooled version; for conduction-cooled, confirm chassis thermal interface plate contact.
Connect AC input via IEC or terminal block per local safety codes; use shielded power cable grounded at chassis.
Enable hot-swap only if system backplane supports it—otherwise, power down before insertion.
?️ Maintenance Tips:
Periodically inspect air filters (if used) and clean heatsinks to prevent thermal throttling.
Monitor output voltages annually using a calibrated multimeter at test points (if accessible).
In high-vibration environments, check mounting screws and connector retention every 6 months.
Store spares in dry, ESD-safe packaging at room temperature; avoid condensation during cold-to-warm transitions.
