Description
The Telkoor CPCI-AC-6U-500 (part number 900-7002-99) is a high-density, high-efficiency 6U CompactPCI (cPCI) Power Supply Unit manufactured by Telkoor Power Supplies.
Designed for high-reliability telecommunications, industrial automation, defense, and embedded computing systems, this hot-swappable module converts standard AC mains input into four tightly regulated DC outputs across the standard CompactPCI Positronic backplane interface.

Core Features & Operating Capabilities
- PICMG 2.11 Compliance: Built according to official CompactPCI power interface specifications, ensuring full interoperability with standard 6U cPCI backplanes and enclosures.
- Active Power Factor Correction (PFC): Integrated active PFC (>0.98 power factor) complies with EN61000-3-2 standards for clean mains power draw.
- N+1 Redundancy & Active Current Sharing: Features internal OR-ing diodes on positive output rails and active current sharing, enabling N+1 redundant parallel power architecture across multiple supply modules.
- Hot-Swap & Blind-Mate Connectors: Fitted with staggered pins on the P47 Positronic connector to support live insertion and extraction without resetting the system chassis.
- Comprehensive Circuit Protection: Onboard protection mechanisms include Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP).
- Front Panel Indicators: Green status LEDs provide visual verification of AC Input OK and DC Output OK rail health.
