Functional Description

IC693PWR322 is a Standard Power Supply developed by GE. It is part of the Mark I and II control systems. The GE Fanuc power supply designed for the Series 90-30 Programmable Logic Controller (PLC) systems. This power supply unit operates on a nominal input of either 24V DC or 48V DC and delivers a 30-watt output. It is specifically designed to be mounted in the standard power supply slot on any PLC baseplate. While it can maintain all outputs within specified limits with input voltages as low as 18V DC, it will not initiate startup with input voltages below 21V DC. It provides three distinct outputs: a +5V DC output, a +24V DC relay output used to power circuits on any IC693 relay output module, and a +24V DC isolated power output for input modules.

Power Calculations and Specifications

• When using the power supply, it is important to calculate the power requirements of the connected PLC modules to ensure that the supply can handle the load. 
• Determine the Total Output Load,  This is the sum of all power requirements from the connected modules. This data can be found in the PLC Installation and Hardware Manual.
• Calculate Input Power,  Multiply the total output load by a factor of 1.5 to estimate the input power required.
• Divide the calculated input power by the operating source voltage to determine the required input current. Since the input voltage can fluctuate, it is recommended to use the lowest measured or estimated input voltage to ensure you are calculating for the maximum current demand.
• The inrush current (4 Amps peak) must be considered, and it is advisable to add a 10-20 percent margin to accommodate any variations in the power supply’s behavior during startup.

Design and Functionality

• It is part of the GE Series 90-30 standard power supply family and does not come with an internal battery. Unlike AC power supplies, this unit is specifically built for a nominal input of 24V DC or 48V DC.
• It maintains its output levels even at the lowest input voltage of 18V DC, though it cannot start if the input voltage is below 21V DC. The three output voltages provided include a standard +5V DC output, a +24V DC isolated output, and a +24V DC relay output.
• The 24V DC relay output supplies power to all relay output module circuits within the Series 90-30 PLC system.

Protection and Reliability

• The module includes current-limiting functionality that helps prevent damage to the internal circuits in case of a short circuit fault. This feature ensures that the power supply shuts down automatically in the event of an overcurrent situation.
• The power supply has an inrush current rating of 4 Amps at a maximum of 100 milliseconds to safely handle the initial surge when the unit is powered on, without damaging sensitive components.
• Automatically adjusts to the input voltage without requiring manual configuration of jumpers, simplifying setup and enhancing user convenience.
• The module offers a minimum hold-up time of 14 milliseconds, ensuring that the system remains operational during brief interruptions in the power supply.
