Internal Design and Power Distribution
This power supply uses a switching converter design for high efficiency. A full-bridge rectifier converts AC to DC for both output rails. The GE IC693PWR321S employs four filtering capacitors for energy storage. These capacitors provide 20 ms of hold-up time during short power interruptions. The 5 V DC output powers the backplane and all logic modules. The 24 V DC output supplies sensor power and relay circuits separately.
Installation and Connection Guide
First, mount this power supply into the leftmost slot of your Series 90-30 rack. Next, connect your AC mains wires to the L, N, and PE terminals on the rear block. Then, wire the 5 V output to your backplane distribution points for logic power. Use the 24 V output for field devices like sensors and relays. The module includes green LEDs for output status monitoring. This unit works with all Series 90-30 racks and CPU models including 311, 331, 341, 363, and 364. Always disconnect AC power before removing the module from the rack.
