Frequently Asked Questions
Can I use the IRM-03-9S to power a small 9V industrial sensor or control circuit?
Yes, it is a constant-voltage 9V supply rated for 3W and 333mA. That makes it a fit for low-power 9V industrial, embedded, or automation circuits that stay within 3W.
Is the IRM-03-9S suitable for embedded 9V electronics inside compact equipment?
It is designed for compact builds, with a 37.0 × 24.0 × 16.0 mm body and miniature encapsulated SMD style construction. Electrically, it provides 9V at up to 333mA, so it fits small embedded loads rather than higher-draw 9V devices.
Can this power supply be used in a low-power automation interface board that needs 9V DC?
It can be used where the board requires a regulated 9V constant-voltage source and the total load is within 3W. The 85-305VAC input also supports use across a wide AC input range in control equipment.
What is the difference between the IRM-03-9S and other IRM-03 models?
Within the IRM-03 group, the options are IRM-03-3.3 at 3W, 3.3V, 900mA; IRM-03-5 at 3W, 5V, 600mA; IRM-03-9 at 3W, 9V, 333mA; IRM-03-12 at 3W, 12V, 250mA; IRM-03-15 at 3W, 15V, 200mA; and IRM-03-24 at 3W, 24V, 125mA. The IRM-03-9S matches the 3W, 9V, 333mA electrical rating, with the S version identified as SMD style.
Is the IRM-03-9S suitable for outdoor or harsh-temperature use?
Its operating temperature range is -30°C to +85°C, so it covers a wide temperature span for equipment design. No IP rating is listed, so it should be treated as a component for protected indoor enclosures or for outdoor use only inside an enclosure that provides environmental protection.
