Key specifications
Output voltage: 9V DC
Output current: 0.333A
Power rating: 3W
Input voltage range: 85-305V AC
Mounting type: PCB mount (SMD)
Design: Encapsulated
How to use
The IRM-03-9S is designed for professional integration onto a printed circuit board. Ensure that the PCB layout accounts for the physical dimensions of the module and provides adequate clearance for heat dissipation. Solder the pins securely to the corresponding pads on your board, ensuring correct polarity alignment. Once installed, connect the AC input lines to the designated input pins and verify the 9V DC output using a multimeter before connecting the load.
What to consider before purchase
Verify that your total load power does not exceed 3W.
Ensure your PCB design supports the SMD mounting footprint.
Check that the operating temperature of your device remains within the manufacturer's specified limits.
Confirm that the input voltage in your region falls within the 85-305V AC range.
Usage recommendations: To ensure maximum longevity and performance, operate the module within its rated power limits and provide sufficient airflow around the component to prevent overheating during continuous operation.
