GE Fanuc IC698PSA350 PACSystems Power Supply Module

The GE Fanuc IC698PSA350 is a high-performance power module engineered specifically for the PACSystems RX7i controller platform. This unit serves as the primary energy source for the system backplane, delivering the necessary power to activate CPU and I/O module circuitry. It installs exclusively in slot 0 of the RX7i rack and occupies a single slot width. Because it supports both AC and DC input ranges, it offers significant flexibility for various global industrial power standards.

Input Versatility and Energy Efficiency

This power supply manages a broad spectrum of input voltages to accommodate diverse operating environments. It accepts universal AC input from 85 to 264 VAC and DC input between 100 and 150 VDC. The module features an impressive 0.99 power factor for AC operations, which optimizes energy usage. While the typical power requirement sits at 440 watts, the unit can handle a maximum load of 500 watts to ensure system stability during peak demands.

Advanced Thermal Management and Safety

Operational safety is a central feature of the IC698PSA350 design. The module includes an integrated 70 CFM forced-air cooling fan to regulate internal temperatures. To prevent hardware failure, the system monitors airflow and thermal levels constantly. If cooling fails or temperatures exceed safe limits, the “OVER TEMP” LED alerts the operator immediately. Furthermore, the unit provides 1500V DC isolation for all outputs, protecting sensitive logic components from input line disturbances.

Diagnostic Monitoring and Physical Specs

Three dedicated LED indicators on the front panel provide real-time diagnostic feedback. These lights track field power status, output health, and thermal conditions. The module also features a ride-through capability of 15 milliseconds, allowing the system to maintain operation during brief power fluctuations. Depending on the hardware revision, the unit utilizes either large 1.25-inch fuses (Series A) or 20mm fuses (Series B) for overcurrent protection.
