4. Product Introduction (Anti-Template)
When a main CPU trips and downtime costs thousands per minute, stable backplane power is non-negotiable. The IC698PSD300C takes a 24 VDC plant supply and delivers clean +5 V, +12 V, and –12 V rails totaling up to 300 W for the entire RX7i rack.
Unlike lower-capacity supplies, this module supports high-current CPU and I/O loads while providing overvoltage, overcurrent, and overtemperature protection. An integrated airflow sensor watches the mandatory fan tray; if cooling is lost the outputs shut down and the red over-temperature LED lights. Revision C carries ATEX Group II Category 3 qualification for certain hazardous-location applications. Install it only in Slot 0.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Origin is traced through manufacturing records. Hardware revision (C), terminal condition, and LED functionality are photographed and logged before testing.
- Live Rig Testing – Module is installed in an RX7i rack with proper fan tray, powered from a controlled 24 VDC source, and checked for correct output voltages, current capability, and LED status under load.
- QA & Anti-Static Packaging – After functional pass, terminals are inspected, the module is cleaned, and it is sealed in anti-static shielding with desiccant and humidity indicator.
- Global Logistics & Export Compliance – Classified under the correct HS code for industrial power-supply modules. Packaging is rated for air and sea freight vibration; export documentation is prepared to reduce clearance delays.
6. Technical Pitfalls & Integration Warnings
Missing Fan Tray – Running the PSD300 without the required rack fan tray causes immediate thermal shutdown once load and ambient temperature rise. The airflow sensor will trip the outputs and light the red LED.
Slot Placement Errors – The module must occupy Slot 0 (leftmost). Installing it elsewhere prevents proper backplane sequencing and can leave the rack without power.
Input Voltage Outside Range – Feeding less than 18 V or more than 30 V DC risks undervoltage dropout or overvoltage damage. Confirm plant supply regulation before energizing.
Hot Insertion / Removal – Never insert or remove the power supply under power. Hazardous voltages exist on the terminals and backplane; doing so risks personal injury and module damage.

7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified IC698PSD300C?
Stock units normally ship within 1–3 business days after payment clearance. Air freight to major industrial regions typically adds 3–8 days once customs processing is complete.
Does this power supply require a fan tray?
Yes. Full 300 W rating demands forced-air cooling. Without the fan tray the unit will thermally limit or shut down.
What are the three output rails and their current limits?
+5 VDC up to 50 A, +12 VDC up to 10 A, and –12 VDC up to 4 A, with a combined maximum of 300 W.
Where does the module mount in the rack?
Only in Slot 0, the leftmost position of the RX7i main rack.
What does the revision C designation mean?
Revision C includes qualification to the Explosive Atmospheres Directive (ATEX) for Equipment Group II, Category 3 hazardous locations. Functionality remains the same as later revisions.
Can the supply ride through short input interruptions?
Yes. Minimum ride-through time is 15 ms, allowing brief input power dips without dropping the DC outputs.
Is hot-swapping permitted?
No. Power must be removed before inserting or removing the module.
