Product Introduction

The IC695PSD140B is physically installed in a PACSystems RX3i IC695 Universal Backplane and supplies the DC rails required by the rack. Unlike the basic PSD040, this multi-purpose version is intended for load-sharing and redundant power configurations, allowing a Universal Backplane to use one unit alone or multiple PSD140 supplies according to the approved system architecture.

Revision B is worth retaining as a separately controlled asset. GE’s release history states that IC695PSD140B, released in May 2010, corrected an issue in earlier versions that could cause intermittent failure to power up in the 16-slot IC695CHS016 Universal Backplane. Later revisions introduced other design, manufacturing, and certification changes, so a warehouse record that says only “IC695PSD140” loses useful engineering information.

Core Technical Specifications

The current Emerson product record confirms the 24 VDC nominal input, 18–30 VDC operating range, 40 W total output capacity, one-slot RX3i installation, redundancy/load-sharing capability, LED diagnostics, and environmental limits.

The power budget deserves careful review. Although the supply is rated 40 W, the published output figures are not intended to be simply summed as independent full-load capacities; actual permitted output depends on the applicable temperature derating and system configuration. GE’s technical documentation also specifies a 60 W maximum input at full load.

🚨 Global Compliance & Industry Certifications

The current Emerson product record lists the IC695PSD140 family with these approval categories:

• UL
• CE
• ATEX
• CCC
• KC
• Marine approvals: ABS, BV, DNVGL

Later product revisions also received updated certification labeling. Emerson’s release history records IECEx and ECAS (UAE) certification additions in the 2023 release. That is important for audit work because these later certification changes do not automatically establish that an older Revision B carries the same approvals or markings.

For hazardous-area deployments, the installation restrictions are explicit. Emerson documentation warns that substitutions can impair suitability for Class I, Division 2 or Zone 2, and equipment must not be connected or disconnected in a hazardous location unless power is removed or the area is confirmed nonhazardous.

Verify specific lot certifications with OEM. The physical certification marks, hardware revision, certificate scope, and project installation requirements should be checked before this Revision B unit is released for a regulated application.

🚨 Long-Term Storage & Asset Preservation Guide

Keep the supply in ESD-safe protective packaging while it remains in stock. The front terminal area, switch mechanism, and electronics should not be exposed repeatedly to warehouse dust or uncontrolled handling.

Avoid condensation during long-term storage. Although the documented storage temperature range extends from -40°C to +85°C, a stable, dry environment is preferable for multi-year preservation. Rapid movement between cold storage and warm humid air can create internal condensation even when the nominal temperature falls within the published range.

Preserve Revision B identification. Keep the original product label and revision marking with the asset record. This particular revision has a defined historical correction for startup behavior in the 16-slot IC695CHS016, so mixing Revision B stock with later revisions without recording the difference weakens configuration control.

For shelf audits, inspect the terminal screws, grounding point, connector surfaces, and front-panel switch without unnecessarily opening the electronic assembly.

Physical Installation Prerequisites

The IC695PSD140B must be installed in a PACSystems RX3i IC695 Universal Backplane. Emerson specifies that the supply occupies one slot and can be used alone or combined with additional PSD140 units for load sharing and redundancy.

• Backplane compatibility: Confirm the chassis is an IC695 Universal Backplane. The PSD140 family is not interchangeable with every RX3i power-supply family in redundancy mode.
• Redundancy rule: Do not combine PSD140 with IC695PSD040 or IC695PSA040 in redundant or increased-capacity configurations; the GE/Emerson documentation explicitly warns that equipment damage can result.
• Input power: Provide a correctly wired 18–30 VDC source with adequate upstream capacity for the 60 W maximum input rating and approximately 4 A / 100 ms inrush.
• Polarity: When multiple power supplies share an external DC source, maintain identical polarity connections at each unit.
• Grounding: Follow the RX3i chassis grounding arrangement and connect the designated frame-ground terminal as required by the installation documentation.
• Cooling: This is a natural-convection industrial power supply. Keep the chassis ventilation path unobstructed and account for the thermal derating curve when operating near the upper ambient limit.
• Clearance: Do not apply a generic 50 mm rule without checking the chassis installation drawing. Service access, wire routing, and adjacent equipment determine the required working space.
• Hot replacement: In redundant configurations, the approved architecture may permit an individual supply to be removed while the remaining supplies maintain the required load. In a single-supply arrangement, remove system power before replacement unless the applicable engineering procedure specifically authorizes another method.
• Hazardous locations: For certified hazardous-area installations, power must be removed before wiring or module replacement unless the area is verified nonhazardous and the applicable certification instructions permit the activity.

Buyer’s FAQ

What HS tariff code should be used for ?

A commercial listing assigns 8504409510 to , placing it within a power-supply classification.

That code should be treated as a reference rather than a universal customs determination. The final 6-, 8-, or 10-digit tariff number can vary by importing country. Have the customs broker confirm the applicable national tariff classification before filing the shipment entry.

Does Country of Origin need to be documented for this revision?

Yes. A commercial listing identifies the United States as the country of manufacture for .

For formal customs use, support the COO with manufacturer records or an appropriate origin declaration. Keep the origin information consistent across the commercial invoice, packing list, and any Certificate of Origin used for the transaction.

Should I purchase shipping insurance for a 0.5 kg power supply?

Weight does not determine the insurance decision; replacement value and operational criticality do. A small industrial power supply can stop an entire RX3i rack if it is the only installed supply. Before dispatch, photograph the Revision B label, serial/date code, terminal area, front switch, and packaging, then retain those records with the freight documentation.

Does include the latest firmware?

A power supply such as is not normally treated like a CPU module with a user-managed application firmware package. Its important identity is the hardware revision and release history. Revision B itself was introduced in May 2010 to address an earlier power-up issue associated with the 16-slot IC695CHS016 backplane. Later hardware revisions introduced other changes, including certification and manufacturing updates.

For a controlled replacement, specify rather than accepting a generic IC695PSD140 unless engineering has explicitly approved a later revision.

Asset-Control Summary

GE is a Revision B PACSystems RX3i multi-purpose 24 VDC, 40 W power supply. Its principal asset-control characteristics are a single-slot RX3i Universal Backplane installation, 18–30 VDC input, 40 W total output capacity, and support for load-sharing and redundancy.

For legacy inventory, keep Revision B segregated and explicitly identified. GE’s May 2010 revision addressed a specific power-up issue, while later revisions introduced additional electrical, manufacturing, RoHS, and certification changes. Treat the revision as a controlled engineering attribute, not merely a warehouse suffix.
