2. Output Power & Channel Parameters
Rated output power is 350W with a maximum peak power of 500W, providing sufficient load redundancy to meet the full-load power supply demand of fully configured RX7i racks with multiple synchronous operating modules. Multiple independent voltage-stabilized output channels: +5VDC (max 60A) for main control and logic loop power supply; +12VDC (max 12A) for signal and drive loop power supply; -12VDC (max 4A) for precision analog loop power supply. Each channel features high voltage stabilization accuracy, excellent load linearity and fast dynamic load response with no mutual interference. It maintains low ripple, zero voltage drift and zero output distortion throughout operation, ensuring stable operation of main control and precision I/O modules.
3. Efficiency & Heat Dissipation Parameters
Adopting active PFC power factor correction technology, the maximum power supply conversion efficiency reaches 90% with low power consumption and controllable heat generation, effectively reducing cabinet thermal load. As a high-power model, IC698PSA350E requires 70CFM standard forced air cooling under rated working conditions of 0℃~60℃ for long-term full-load stable operation; without forced air cooling, load derating must be performed strictly according to the temperature derating curve to avoid overheating frequency reduction, power attenuation and protective shutdown. Built-in airflow monitoring sensors monitor heat dissipation duct status in real time and trigger automatic abnormal airflow alarm and protection.
4. Protection & Diagnosis Parameters
Integrated full-dimensional hardware self-locking protection mechanisms cover input over/undervoltage, output overcurrent, output short circuit, overheating and airflow loss. It quickly cuts off abnormal output and latches fault status upon failure to prevent fault propagation and damage to rear-end high-value main control and I/O modules. The onboard power self-check circuit monitors input voltage, output load, module temperature and heat dissipation status in real time, and fault codes can be read via system configuration software for accurate fault positioning. It delivers excellent industrial-grade EMC electromagnetic compatibility, anti-vibration and temperature resistance performance for harsh industrial sites.
5. Environmental Operating Parameters

It features perfect fault tolerance and convenient maintenance, minimizing risks of system shutdown, equipment damage and production interruption caused by power faults.
5. Supports Redundant Hot Backup & Commissioning-Free In-Situ Replacement
Natively supports dual-power redundant hot backup networking for RX7i systems, with dual modules backing up each other and balancing loads. Single power failure will not affect the continuous operation of the entire system, greatly improving the reliability of industrial control systems. The hardware dimensions, backplane interfaces, electrical parameters and diagnostic protocols fully comply with RX7i system standards. Outdated modules with insufficient power, failed heat dissipation, attenuated load capacity and frequent faults can be directly replaced in situ without system configuration modification or shutdown commissioning. Full-load operation is available after power-on self-test, drastically reducing technical renovation and maintenance downtime costs.
IV. Working Principle
GE IC698PSA350E is a dedicated high-power rack power supply module for GE PACSystems RX7i large-scale industrial control systems. After being embedded in the system standard rack backplane and electrically connected, it automatically completes hardware self-test, loop initialization, voltage calibration, airflow detection and fault clearing upon power-on, and enters the normal working state of high-power voltage-stabilized power supply.
The front-end wide-range AC/DC input power first passes through the module's multi-stage EMI filtering and rectification loop for clutter filtering, harmonic suppression and voltage normalization. The active PFC power correction unit optimizes power supply efficiency and corrects power factor. After voltage reduction and shaping via the high-frequency switching voltage stabilization architecture, it is divided into three independent pure voltage-stabilized power supplies of +5VDC, +12VDC and -12VDC, which supply continuous and stable working power to rack-mounted CPUs, I/O modules, communication expansion units and functional modules through the backplane bus.
The module monitors input voltage, output load, module temperature and duct airflow status in real time throughout operation, and identifies various power supply and heat dissipation abnormalities via multi-hardware fault tolerance mechanisms. It maintains efficient and stable voltage-stabilized output to adapt to dynamic system load changes under normal conditions; instantly latches faults, cuts off abnormal output and uploads fault information under faulty conditions to protect rear-end core industrial control equipment. It supports dual-module redundant hot backup coordination with seamless switching upon single-module failure, continuously ensuring uninterrupted, high-safety and high-stability closed-loop operation of the entire RX7i industrial control system.
