DIGITAL POWER CPCI-AC-6U-500 (900-7002-99) – 500 W CompactPCI AC Power Supply for 6U Systems

The DIGITAL POWER CPCI-AC-6U-500 (P/N 900-7002-99) is a 6U CompactPCI hot‑swap power supply designed for mission‑critical industrial, telecom, and transportation platforms. From my experience, it’s the type of PSU you choose when you need stable multi‑rail outputs, predictable behavior under load, and straightforward field service—pull the failed unit, insert a replacement, and the chassis is back online within minutes.

You might notice that it follows the typical cPCI power architecture: universal AC input with active PFC, standard +5 V and +3.3 V logic rails, ±12 V auxiliary rails, plus a standby line. That means it drops into most PICMG‑compliant 6U cPCI chassis without surprises, including mixed‑load systems with dense CPU blades and I/O cards.

Order Placement Process and Guarantees

• Warranty: 365 days coverage from delivery.
• Lead Time: 1 week for in‑stock items; no more than one month at the latest.
• Payment Terms: 50% advance payment; full balance prior to delivery.
• Shipping Options: Express via FedEx, UPS, or DHL.

One thing I appreciate is the predictable lead time—teams planning a maintenance window typically don’t want to gamble on availability. If you’re coordinating a multi‑slot refresh, we can batch units to match your schedule.

Key Features

• 6U CompactPCI, front‑pluggable hot‑swap: Designed for quick replacement without shutting down the entire chassis.
• 500 W continuous output: Stable power for dense CPU blades and I/O cards in performance‑heavy systems.
• Universal AC input with active PFC: Typically 90–264 VAC, 47–63 Hz; suitable for global deployments.
• Multi‑rail outputs: +5 V, +3.3 V, ±12 V and +5 VSB to cover logic, drives, and auxiliary needs.
• PICMG power interface compatibility: Fits standard 6U cPCI backplanes for straightforward integration.
• Status and control signals: DC OK/FAIL, Inhibit/Enable, Remote Sense on logic rails; I²C/SMBus monitoring on many builds.
• Integrated cooling: Internal fan with guided airflow for reliable thermal performance in sealed racks.
• Comprehensive protection: OVP, OCP, SCP and thermal protections to safeguard both PSU and backplane.

Application Fields

This model suits platforms where uptime and lifecycle stability matter:

• Telecom and networking nodes (6U cPCI base stations, aggregation routers)
• Industrial automation controllers and data acquisition racks
• Defense and aerospace ground systems using cPCI blades
• Transportation systems (rail signaling, wayside monitoring) with controlled cabinets
• Test & measurement chassis with mixed digital/analog payloads

A customer in rail infrastructure told us their maintenance team swapped a failed PSU during a 20‑minute window without pulling other cards—hot‑swap saved a full shift of downtime.

Advantages & Value

• Reliability first: Conservative thermal design and standard protections usually mean fewer nuisance trips in real deployments.
• Compatibility with cPCI ecosystems: Fits PICMG‑aligned backplanes and common 6U chassis—less re‑engineering, quicker installs.
• Cost control: 500 W capacity covers most 6U builds without over‑specifying a higher‑wattage unit.
• Serviceability: Hot‑swap module design reduces MTTR; spares strategy is straightforward.
• Technical support: We assist with backplane checks, load budgeting, and airflow planning to minimize commissioning risk.

Installation & Maintenance

• Cabinet & chassis: Install in a 6U CompactPCI chassis with proper card guides and a PICMG‑compliant backplane. Ensure adequate front‑to‑rear ventilation.
• AC wiring: Use a properly rated AC feed; earth/ground must be reliable. For systems with front IEC inlet, use an approved IEC 60320 C13/C14 cordset.
• Load budgeting: Balance +5 V and +3.3 V draws; observe combined rail limits. Leave headroom for inrush and transient loads.
• Hot‑swap handling: Engage the ejector handles fully; wait for DC OK before loading the chassis. From my experience, this avoids intermittent resets on sensitive CPU blades.
• Routine maintenance: Quarterly dust cleaning on intake/exhaust, verify fan spin and alarm signals, and log output voltages under load.
• Firmware/monitoring: Where I²C/SMBus is available, periodically read status logs (temperature, fan, fault history) for predictive maintenance.
• Safety: De‑energize the AC feed before any non hot‑swap service. Observe ESD precautions around backplane connectors.

Quality & Certifications

• Manufactured to meet CE and RoHS requirements
• Safety evaluated to IEC/EN/UL 60950‑1 or IEC/EN/UL 62368‑1 (varies by production date)
• EMC designed for industrial environments; conforms to typical cPCI chassis emissions/immune setups
• 365‑day warranty with replacement support

Supporting Components & Compatibility

For smoother deployments, we can pair the CPCI-AC-6U-500 with:

• 6U CompactPCI chassis and PICMG 2.11‑compliant backplanes (single or redundant PSU bays)
• Approved IEC C13/C14 power cords and filtered power entry modules
• Blanking panels and airflow baffles to maintain thermal balance when operating with a single PSU
• Field spare fan kits and ejector handle hardware, where applicable
