Functional Description

IC200PWR002 is an Expanded Power Supply Unit developed by GE. It plays a vital role in supplying power to various backplane devices, including Central Processing Units (CPUs), Network Interface Units (NIUs), and input/output (I/O) modules. When connected to either a CPU or an NIU, functions as the primary power source for the system, providing the necessary voltage and current to keep the components operational. Additionally, this power supply unit can be mounted on a booster carrier, allowing it to act as supplementary power, ensuring stable and continuous operation across expanded configurations.

Input Voltage and Power Requirements

• It operates on direct current (DC), with its input voltage ranging between 18 volts and 30 volts DC. The nominal input voltage is set at 24 volts DC, which is the standard operating voltage for this module. The power unit’s input power consumption is rated at 11 watts, making it an efficient component in terms of energy usage.
• However, it’s important to note that the inrush current - the surge of current required when the unit is first powered on varies depending on the input voltage. At 24 volts DC, the inrush current is rated at 20 amperes, while at 30 volts DC, it increases to 25 amperes. This high inrush current is typical for power supplies that need to handle large initial energy demands when powering up automation equipment.
• Hold-up time for this power supply is approximately 10 milliseconds. This time period refers to how long the power supply can maintain the output voltage after a power loss, allowing the system to continue operating temporarily or to initiate a safe shutdown process in case of a power failure.

Output Voltage and Current Capacity

• Provides two key output voltages: 3.3 volts DC and 5 volts DC, which are critical for supplying power to different types of backplane devices within the system. The total output current depends on the specific combination of the 3.3V and 5V outputs.
• However, it is crucial to ensure that the combined output current does not exceed 1.5 amperes. This current limit is designed to protect the power supply and connected components from overcurrent conditions, which could lead to overheating or component failure.

Protection Features

• Short Circuit Protection: This feature safeguards the power supply and the connected devices from damage caused by unexpected short circuits.
• Overload Protection: It helps prevent the power supply from being damaged due to excessive current draw by the connected devices.
• Reverse Polarity Protection: If the wiring is incorrectly configured (i.e., if the positive and negative connections are reversed), this protection feature prevents damage to the power supply and other components in the system.

Grounding and Wiring Considerations

• When wiring, proper grounding is crucial for ensuring safety and optimal performance.
• The DC- -terminal (the negative terminal) must be grounded to both the frame ground and the earth ground. This ensures that the power supply and the overall system are safely connected to the ground, reducing the risk of electrical faults or hazardous conditions. It’s also important to note that the DC- terminal is internally grounded to the frame within the power supply unit itself.
• As a result, a floating power supply configuration, where the negative terminal is not connected to ground, is not possible with this module.
