Product Introduction

Compact, lightly populated RX7i control racks often do not require high-wattage forced-air power supplies. GE provides stable multi-rail backplane power for systems with minimal I/O and communication hardware, eliminating fan-related failure points typical of higher-capacity alternatives.

This unit supports both AC and DC plant power feeds without jumper adjustments. Fanless construction lowers routine maintenance requirements and reduces airborne particulate ingestion inside control cabinets. The fixed slot-0 mechanical footprint allows direct drop-in replacement for existing spare changeouts during planned downtime.

Key Selling Points & Differentiators

1. GE utilizes passive convection cooling; no internal fan to wear out, making it suitable for low-maintenance auxiliary control and remote cabinet deployments.
2. Auto-ranging AC/DC input removes voltage selection jumpers, simplifying standardization across multiple facility power infrastructures.
3. Every unit undergoes full backplane load bench validation before shipment; signed test documentation available on formal request. Warranty coverage runs 12 months post delivery.
4. Optimized for low-density RX7i rack layouts, reducing unnecessary power headroom and thermal load within enclosed enclosures.
5. Not recommended for heavily populated racks. The 100 W rating cannot support full chassis loads that require IC698PSA350 high-capacity power supplies.
6. Identical front panel mounting interface matching OEM specifications; no wiring modifications required during exchange.

Quality Transparency SOP

• Incoming Verification: Serial traceability validation, anti-counterfeit visual inspection, fuse and terminal hardware cross-check.
• Live Bench Test: Dedicated RX7i test chassis, power-on self-test, partial backplane load simulation, continuous 24-hour thermal cycling, LED function verification.
• Electrical Tests: Input voltage range sweep, overcurrent trigger testing, insulation resistance via 500 V megger, ground continuity validation.
• Hardware Verification: Confirm internal protection circuits function per datasheet; no unauthorized component rework performed.
• Final QC & Packaging: Anti-static shielding, shock-dampened transit carton, signed QC Pass label. Test images and logs available on request. No zero-failure performance guarantee.

Technical Risk Avoidance Section

Rack Slot Placement Risk Risk: Installing the unit in any slot other than Slot 0 prevents backplane power routing and triggers immediate module fault states. Prevention: Reserve the leftmost chassis slot exclusively for this unit. Field note: Multiple integrators reported non-booting RX7i systems after misplacing power supplies into CPU or I/O slots during outage work.

System Load Miscalculation Risk Risk: Overloading the 100 W rating with high-power CPUs, analog I/O, or multiple communication cards causes voltage sag and spontaneous chassis resets. Prevention: Sum total DC power draw of all installed modules and maintain minimum 15% power headroom. Select IC698PSA350 for dense rack configurations.

ESD Damage Risk Risk: Unprotected handling damages internal switching semiconductors without immediate visible failure symptoms. Prevention: Use grounded wrist straps; keep the module inside anti-static packaging until rack insertion.

Cabinet Thermal Management Risk Risk: Poor cabinet ventilation can push ambient temperatures above 60 °C, triggering overtemperature shutdown even with fanless hardware. Prevention: Maintain clear airflow paths around the rack and verify cabinet exhaust ventilation.

Critical Summary: Confirm chassis load calculation before ordering. This unit cannot be installed in RX3i racks, and it must occupy Slot 0 on all RX7i VME backplanes.

FAQ

1. Q: Can GE be installed into RX3i PACSystems racks? A: No. It is built exclusively for RX7i VME64 backplanes. RX3i uses separate series power supplies with different mechanical and electrical specifications.
2. Q: Does this module support hot-swap replacement while the RX7i chassis remains energized? A: Hot swap is not supported. Removing the unit cuts all backplane power, triggering full system shutdown. Planned outages are required for exchange.
3. Q: What lead times apply for available inventory? A: In-stock units ship within 1–3 business days. Backordered allocations require 5–7 week lead times subject to global surplus availability.
4. Q: What is the key difference between and IC698PSA350? A: delivers 100 W with fanless convection cooling for lightly loaded racks. IC698PSA350 supplies 350 W and requires rack forced airflow for dense, high-current module configurations. The two units are not interchangeable based purely on form factor; load capacity must be validated.
5. Q: What failure modes fall outside warranty coverage? A: The 12-month limited warranty covers manufacturing defects. Damage from overvoltage, improper slot placement, ESD, and sustained overload operation is excluded.
6. Q: Can multiple units operate in redundant parallel configuration on a single RX7i rack? A: The standard RX7i chassis architecture supports only one power supply module per rack. Redundant power is implemented upstream at the cabinet AC/DC distribution level.
7. Q: Can I use either AC or DC plant power as the input source? A: Yes, the unit auto-senses AC or DC input within the rated range; no internal jumper adjustment is needed. Verify wire sizing matches terminal current ratings.
