VANGUARD CPCI-350Q-P-38 PSMU-350-3 – AC Power Supply Module | CompactPCI Platform
Engineering Background
The VANGUARD CPCI-350Q-P-38 (PSMU-350-3) is an AC input power supply module engineered for CompactPCI (CPCI) chassis environments. Designed to meet the rigorous demands of industrial automation, telecommunications infrastructure, and defense-grade embedded computing, this unit delivers stable, regulated DC outputs from a standard AC mains input. VANGUARD’s PSMU series is recognized for its high mean time between failures (MTBF) and compliance with PICMG 2.11 power interface standards.
Product Positioning
Targeting procurement engineers and system integrators who require a drop-in replacement or new-build power solution for 3U/6U CompactPCI backplanes, the CPCI-350Q-P-38 bridges legacy system longevity with modern efficiency requirements. It is stocked and verified by Konmask.com as a genuine, tested unit suitable for mission-critical deployments.

System Architecture & Signal Flow
The CPCI-350Q-P-38 accepts universal AC mains input through an IEC inlet with integrated EMI filtering. The power factor correction (PFC) stage boosts the rectified DC bus to a regulated intermediate voltage. A high-frequency DC-DC converter stage then generates the PICMG-compliant output rails (+3.3 V, +5 V, +12 V, −12 V). Output rails are distributed to the CompactPCI backplane via the PSMU connector, powering all installed peripheral and processor boards. An onboard management controller monitors rail voltages, temperatures, and fan status, asserting fault signals to the system host via the CPCI management bus.

Technical FAQ
Q: Is the CPCI-350Q-P-38 compatible with both 3U and 6U CompactPCI chassis?
A: The PSMU-350-3 is designed for the CPCI power slot as defined by PICMG 2.11. Compatibility depends on your specific chassis manufacturer’s power slot implementation. Please share your chassis model for confirmation.
Q: Can this unit operate on 48 VDC input instead of AC?
A: No. The CPCI-350Q-P-38 is an AC input module. For DC input requirements, contact Konmask.com for alternative VANGUARD PSMU variants.
Q: What is the lead time for volume orders (>10 units)?
A: Volume orders are subject to stock availability. Submit an RFQ to support@konmask.com for a committed delivery schedule.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC is available upon request for all orders. VANGUARD factory CoC or Konmask inspection CoC can be provided depending on procurement requirements.
