The IC698PSA350D belongs to the RX7i high-capacity power-supply family. GE documentation specifies the IC698PSA350 as a 350 W power supply with +5 VDC, +12 VDC, and -12 VDC outputs for the RX7i backplane.

Key Technical Specifications

The documented RX7i architecture places the power supply directly in the leftmost slot of the rack. The 350 W version provides substantially more +5 V capacity than the 100 W supply, with a rated +5 V output of up to 60 A.

The “D” suffix should be matched exactly when replacing an installed unit. Do not assume that every IC698PSA350 listing represents the same revision or physical configuration.

Product Introduction (Anti-Template)

When an RX7i rack contains a large number of VME and I/O modules, the power budget becomes a hard engineering limit rather than a theoretical specification. The GE IC698PSA350D is the high-capacity power-supply option for the PACSystems RX7i platform, delivering up to 350 W across the rack’s +5 V, +12 V, and -12 V supply rails.

Its AC input accepts 85–264 VAC, while the supply can also operate from 100–150 VDC. The +5 V rail is rated up to 60 A, which is where most of the available output capacity sits. A fan tray is required when operating at the full rated capacity.

QC, Procurement & Logistics SOP

1. Inbound Verification
   • Confirm the complete catalog number: IC698PSA350D.
   • Check the nameplate, revision marking, serial number, and input-rating information.
   • Inspect the AC input terminals and rack connector for damage.
   • Check the cooling interface and fan-tray connection.
   • Verify that the customer’s rack is a PACSystems RX7i rack.
   • Confirm the installed rack load before approving the replacement.
2. Live Rig Testing
   • Apply the appropriate AC input using a controlled test setup.
   • Verify startup behavior and output regulation.
   • Measure the +5 VDC, +12 VDC, and -12 VDC rails.
   • Check for abnormal noise, overheating, or fault indications.
   • Verify stable output under representative load where test equipment permits.
   • Record measured output values and serial number.
3. QA & Anti-Static Packaging
   • Photograph the model and rating label before shipment.
   • Protect the rack connector from mechanical impact.
   • Use ESD-safe packaging around the electronic assembly.
   • Use rigid cushioning around the power-supply housing.
   • Prevent terminal damage caused by movement inside the carton.
4. Global Logistics & Export Compliance
   • Prepare the commercial invoice, packing list, product description, origin information, and applicable HS classification.
   • Use a clear description such as GE PACSystems RX7i 350 W industrial PLC power supply.
   • Air freight is normally suitable for a single power-supply module.
   • Use reinforced packaging because the unit is considerably heavier than a typical control card.
   • Confirm the final HS classification with the destination customs broker before export declaration.

Technical Pitfalls & Integration Warnings

1. Rack Power Calculation

Do not determine compatibility simply because the replacement has the correct connector.

The RX7i rack’s total module load must remain within the power supply’s output capability. The IC698PSA350 provides up to 350 W total, with the +5 V rail rated at 60 A.

Scenario: A customer adds several high-current modules and replaces a 100 W supply with a 350 W unit. The system still behaves unpredictably because the actual load, cooling arrangement, or rack configuration was never checked.

Calculate the rack load first.

2. Fan Tray Requirement

This is easy to overlook. GE documentation states that the 350 W supply requires forced-air cooling for full-capacity operation.

Scenario: The supply is installed correctly and produces the expected voltages at startup, but the rack becomes thermally unstable under sustained load because the required fan arrangement is missing.

Do not treat the fan tray as an optional accessory when operating at the full rating.

3. Input Voltage Confusion

The supply accepts a wide AC range of 85–264 VAC, but the terminal arrangement and installation procedure still matter. It can also accept 100–150 VDC input.

Verify the actual plant supply before wiring. A wide input range does not eliminate the need for correct terminal wiring and grounding.

4. Do Not Hot-Swap the Power Supply

This is not a control card that should be pulled from an energized rack.

GE installation documentation states that power should be turned off before replacing or wiring the power supply, particularly in hazardous locations.

Honestly, shutting down the rack is far cheaper than turning a power-supply replacement into a backplane repair.

Frequently Asked Questions (FAQ)

Q1: What is the GE IC698PSA350D used for?

It is a 350 W rack power supply for the PACSystems RX7i PLC platform. It supplies the +5 VDC, +12 VDC, and -12 VDC rails required by modules installed in the RX7i rack.

Q2: What input voltage does IC698PSA350 support?

The documented input range is:

• 85–264 VAC
• 47–63 Hz
• 100–150 VDC

Nominal ratings are 120/240 VAC and 125 VDC.

Q3: How much power does it provide?

The maximum total output is 350 W:

• +5 VDC: up to 60 A
• +12 VDC: up to 12 A
• -12 VDC: up to 4 A

The actual usable rack capacity still depends on the individual module load requirements.

Q4: Can IC698PSA350D replace IC698PSA100?

They belong to the same RX7i power-supply family, but they are different capacity options. IC698PSA100 is rated at 100 W, while IC698PSA350 provides 350 W.

A higher-capacity supply should not be treated as an automatic replacement without checking the rack configuration, cooling requirements, and exact hardware revision.

Q5: Does IC698PSA350 require a fan?

Yes, forced-air cooling is required for full-capacity operation of the 350 W supply. GE’s documentation specifically references the required rack fan arrangement.

Q6: Can it be hot-swapped?

No. Follow the approved shutdown procedure before removing or wiring the power supply. GE installation documentation specifically instructs that power be turned off before replacement or wiring in relevant applications.

Q7: What is the approximate shipping weight?

A published listing gives approximately 2.1 kg gross weight for the . For freight quotation, I would budget around 2.5–3 kg packed, depending on the carton and protective material.

Q8: What should I provide when ordering a replacement?

For a proper compatibility check, provide:

• Full model:
• Nameplate photograph
• Hardware revision
• Existing RX7i rack model
• CPU model
• Number and types of installed modules
• Existing power-supply model
• Fan-tray model
• Current power-supply alarm or failure symptoms

The rack load and cooling arrangement are the two details I would verify before approving this replacement.
