General Information

Core Description

The IC693PWR330 is a high capacity GE Fanuc power supply module rated for 30 watts output. Fully compatible with the Series 90-30 backplane, this unit features flexible multi-voltage input ranges and works seamlessly with heavy-load configurations to deliver the maximum 30W capacity entirely to the +5V rail for stable industrial system operation.

Specific Application

• Providing full 30-watt capacity to the +5V backplane rail in specialized Series 90-30 applications requiring high-current microprocessor and communication modules.
• Supplying power to external circuitry and field devices via the isolated +24 VDC output loop for 24 VDC input modules.
• Driving output circuit loads for Series 90-30 Output Relay modules using the dedicated +24 VDC relay power subsystem.

Ordering Information

System Compatibility

Backplane Integration: Slots directly into the dedicated power supply slot of standard GE Fanuc Series 90-30 PLC baseplates.

Input Infrastructure: Interfaces with universal networks delivering 85 to 264 VAC or 100 to 300 VDC power sources.

Module Control: Fully compatible with Series 90-30 Input, Output, and Relay modules requiring standard internal or isolated external voltage rails.

Alternative Models & Functional Differences

IC693PWR321 (Standard Power Supply): The standard supply has a smaller +5V current delivery capacity compared to the high-capacity model. The IC693PWR330 expands on this by allowing the entire 30-watt system budget to be funneled directly through the +5V output if needed.

DC-Input Only Supply Models: Unlike the IC693PWR330, which accepts both AC and DC sources on its main terminals without regard to polarity, dedicated DC-only versions are strictly polarity-sensitive and cannot accept AC utility inputs.

Installation & Troubleshooting FAQ

Q1: Are the DC power source connections on the main terminal strip polarity-sensitive?

A: No. When connecting a nominal 125 VDC source to the top two terminals of the terminal connector, the lines are completely non-polarity-sensitive on this AC/DC input power supply.

Q2: What happens to the programmable logic controller if the isolated 24 VDC supply output faces an overload or short-circuit?

A: If the Isolated 24 VDC supply loop is subjected to an electrical overload or a short-circuit condition, the Programmable Logic Controller will immediately stop operation.

Q3: How can the built-in overvoltage protection devices be disabled for a high-potential (Hi-pot) test?

A: The overvoltage protection devices are wired internally to pin 4 and tied to the pin 3 frame ground via a factory jumper strap. To safely perform a Hi-pot test without damage, you must completely remove this terminal strip jumper strap before testing.

Q4: What is the maximum combined output capacity allowed across all three voltage rails?

A: While the +5 VDC rail can supply 30 watts, the +24 VDC Isolated rail can supply 20 watts, and the +24 VDC Relay rail can supply 15 watts independently, the combined simultaneous load of all three outputs together must never exceed 30 watts total.

Q5: What is the rated minimum holdup time provided by this power supply during a line power interruption?

A: This unit provides a minimum holdup time of 20 milliseconds, ensuring the system can ride through minor utility voltage drops or brief line disruptions without dropping the controller offline.
