The Jasper specification lists the AC PCI354-1022 output rails as 5.0 V/40 A, 3.3 V/40 A, +12 V/9 A, and -12 V/1 A, with total loading limited to 350 W. The unit supports 90–264 VAC input and is designed for hot-swap and N+1 redundant operation.
The -38 configuration uses a 38-pin connector. Jasper’s documentation distinguishes this from the standard 47-pin configuration and specifies different connector and guide-rail offsets for the 38-pin version.
Product Introduction
The Jasper Electronics PCI354-1022-38 is a 350 W multi-output power supply designed for 6U CompactPCI and industrial computer platforms. It converts AC input into the multiple DC rails required by processor boards, peripheral cards, backplanes, and other CompactPCI hardware. Its output set includes +5 V, +3.3 V, +12 V, and -12 V.
This is a power subsystem component, not a PCI data-processing board. That distinction matters during procurement because several secondary listings incorrectly associate the part number with industrial controllers or I/O hardware. The Jasper documentation clearly identifies the PCI354 family as a 350 W power-supply series.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
When an older CompactPCI computer starts rebooting, dropping cards, or failing to initialize, the processor board is not automatically the culprit. A degraded power supply can produce marginal +5 V or +3.3 V rails that cause several apparently unrelated cards to fault simultaneously.
Typical Applications
- 6U CompactPCI industrial computers
- Legacy industrial control computers
- Industrial data-acquisition platforms
- Telecom and instrumentation chassis
- Embedded computing systems requiring multiple PCI supply rails
- N+1 redundant CompactPCI power architectures
Technical Pitfalls
- Do not confuse PCI354 with a PCI controller card.
The is a power-supply family. The 1022 configuration provides the +5 V, +3.3 V, +12 V, and -12 V rails required by the host system. - The “-38” suffix matters.
The part uses the 38-pin I/O connector option. A 47-pin variant should not be assumed to be mechanically interchangeable. Jasper documents separate connector configurations and physical offsets. - Check the backplane connector before installation.
Jasper specifies a particular mating connector for the 38-pin version. Connector sequencing is part of the power-interface design, so a physically similar connector is not necessarily an acceptable substitute. - Cooling is part of the power rating.
Full-load operation requires forward airflow. Jasper specifies approximately 120 CFM minimum for the AC 38-pin configuration. A replacement installed in a poorly ventilated chassis may not deliver its rated 350 W continuously. - N+1 operation requires load sharing to be configured correctly.
The supply supports single-wire current sharing on the +5 V, +3.3 V, and +12 V outputs. Do not assume that simply installing two supplies creates a properly engineered redundant power system. - Verify all rails under load.
A supply can appear functional with no load while exhibiting excessive droop or ripple when the processor and peripheral cards are active. For a replacement, measure the principal rails at the system operating load rather than checking only the presence of AC input. - Check the PF, remote enable, and inhibit signals.
The 38-pin interface provides control and monitoring functions including remote enable, remote inhibit, power-fail indication, remote sense, and current-sharing signals. These should be compared with the chassis wiring before commissioning.

Procurement Note
For a replacement, specify the complete PCI354-1022-38 designation rather than simply ordering a “ power supply.” The critical identifiers are the electrical configuration, AC input, 350 W rating, and 38-pin connector arrangement.
Before installation, compare the original unit’s connector position, guide-rail offset, latch arrangement, backplane mating connector, and chassis airflow. Also verify the host system’s actual rail loading. A 350 W rating by itself does not establish interchangeability with another CompactPCI power supply.
The part is also reported as discontinued by the manufacturer in current secondary procurement records, so for legacy equipment it is worth preserving a tested spare and documenting the installed configuration before the existing PSU fails.
