GE IC693PWR330G: High-Output Power Supply for Series 90-30 PLC

Core Function of This Power Supply Module

The GE IC693PWR330G converts AC line power into stable DC voltages for the PLC system. This power supply module powers the CPU, I/O modules, and other racks. It provides overvoltage and short-circuit protection for all connected components. Consequently, the unit ensures reliable operation of the entire control system.

Physical Dimensions and Module Construction

This power supply module measures 140 mm in total length. Its width reaches 115 mm for a standard Series 90-30 form factor. The module depth stands at 115 mm including the front connector and heat sink. You will find 245 discrete components on this heavy-duty PCB. These include switching transistors, transformers, filter capacitors, and regulation circuits. The GE IC693PWR330G weighs approximately 680 grams for secure mounting.

Input Voltage and Power Ratings

The GE IC693PWR330G accepts 85 to 264 V AC input voltage. This wide range covers 120 V and 230 V nominal supplies worldwide. The module also accepts 100 to 300 V DC input for battery-backed systems. The input frequency range spans from 47 to 63 Hz for global compatibility. The unit draws a maximum input current of 2.5 A at 115 V AC.

Output Specifications and Capacity

This power supply module delivers three isolated DC output voltages. The main 5 V DC output provides up to 30 A for logic circuits. The 24 V DC relay output supplies up to 3 A for I/O devices. An isolated 24 V DC user output provides up to 1 A for field sensors. The 5 V DC output includes remote sense lines for voltage drop compensation. Total combined output power reaches 150 W continuously.

Output Connectors and Distribution

The GE IC693PWR330G uses a 5-pin terminal block for AC input wiring. A 20-pin ribbon cable header distributes +5 V DC to the backplane. Two 4-pin headers provide the 24 V DC relay and user outputs. The module also includes a 2-pin connector for the remote sense lines. All output connectors feature keyed housings to prevent incorrect connections.

Protection Features and Diagnostics

This power supply module includes comprehensive protection circuits. Overvoltage protection activates if any output exceeds safe levels. Short-circuit protection limits current during output faults. Overtemperature protection shuts down the module if internal temperature rises too high. A green LED indicates the presence of 5 V DC output. A red LED signals any fault condition requiring attention.

Energy Storage and Hold-Up Time

The GE IC693PWR330G incorporates four 1,000 µF bulk capacitors on the 5 V output. These capacitors store energy to bridge brief input power interruptions. The hold-up time reaches 30 milliseconds at full rated load. Total stored energy reaches approximately 0.4 joules at nominal voltage. This storage prevents CPU resets during momentary voltage sags.

Installation and Wiring Notes

You must install this power supply in the leftmost slot of the main rack. Always connect the ground terminal to the system earth before applying power. Then, verify that the input voltage selector matches your line voltage. The module automatically recovers from fault conditions once you remove the cause. Regular inspection of the cooling vents prevents overheating from dust accumulation.
