Frequently Asked Questions
Can I use the IRM-02-9S in a compact embedded product that needs 9V DC from AC mains?
Yes, it provides a constant 9V output rated at 2W from an 85-305VAC input. Its SMD style and 33.7 × 22.2 × 16.0 mm body make it suitable for compact board-level power sections in embedded equipment.
Is the IRM-02-9S a good fit for low-power 9V industrial interface electronics?
It is intended for low-power 9V loads that stay within the 2W output rating. That aligns with small interface, monitoring, or auxiliary electronics rather than heavier 9V devices.
Can this model power a small 9V automation controller board?
Yes, if the controller uses a regulated 9V supply and remains within 2W output demand. The wide 85-305VAC input range is useful where the same design may be used across different AC mains environments.
Does the IRM-02-9S work for harsh indoor temperature conditions?
The specified operating range is -30°C to +85°C, which supports demanding indoor equipment environments. No IP rating is provided, so the specs do not identify it as suitable for exposed outdoor use or washdown areas.
What is the difference between the IRM-02-9S and the other 9V IRM models?
Within the 9V range, IRM-01-9 and IRM-01-9S are 1W, 9V, 111A; IRM-02-9 and IRM-02-9S are 2W, 9V, 222A; and IRM-03-9 and IRM-03-9S are 3W, 9V, 333A. The IRM-02-9S is the 2W SMD style option, while IRM-02-9 is the 2W PCB mounting style version.
