IC697PWR748 GE Power Supply Procurement Guide

The GE IC697PWR748 90W power supply for Series 90-70 racks operates on a 38-60 VDC input and delivers 5 VDC at 18A, 12 VDC at 1.5A, and -12 VDC at 1A [1]. It features a 10ms ride-through time, an overvoltage limit of 6.5 to 6.9 VDC, and is designed to ensure continuous operation in harsh industrial environments [1]. For complete specifications and installation details, consult the GE GFK-0448 manual.

Core Value
The GE IC697PWR748 power supply resolves critical power instability issues in heavy industries. It ensures continuous operation in oil and gas refineries and chemical plants. Consequently, it reduces downtime and enhances system reliability. This module also supports dual rack configurations without extra cables. Therefore, it offers flexibility for expanding control systems in manufacturing facilities. Its robust design withstands harsh environments like power generation sites. Ultimately, it provides a stable 90-watt output for logic level signals. This eliminates common voltage drop problems in Series 90-70 racks.

Technical Insights
The IC697PWR748 power supply delivers a ride-through time of 10 milliseconds at 20 VDC. This parameter prevents data loss during brief input interruptions. Consequently, it maintains system integrity in continuous processes. The module provides three output voltages: 5 VDC at 26 amps, 12 VDC at 4 amps, and -12 VDC at 2 amps. This flexibility supports diverse logic levels for controllers and I/O modules. Therefore, it simplifies power distribution across the rack. The input voltage range spans 18 to 32 VDC with an inrush energy limit of 22 joules. This ensures stable startup even with fluctuating plant power. Furthermore, the overvoltage limit of 5 VDC protects sensitive components from surges. These specifications extend equipment lifespan and improve production efficiency in automated lines.

Installation and Maintenance Guide
For optimal performance, install the IC697PWR748 module on the leftmost slot of the rack. Ensure the backplane connector is clean and secure before insertion. This prevents intermittent power faults that cause system errors. When connecting a second rack, use the specified cable and keep total load under 90 watts. Additionally, verify ambient temperature stays below 60 degrees Celsius. Higher temperatures require derating to avoid overheating. Regularly inspect input wiring for loose connections or corrosion. This simple check reduces unexpected shutdowns in harsh industrial settings.
