Frequently Asked Questions
Can I use the IRM-03-15S for a low-power 15V analog or instrumentation circuit?
Yes, it provides constant-voltage 15V output rated at 3W. That makes it suitable for small 15V analog, sensing, or instrumentation circuits that stay within the 3W capacity.
Is the IRM-03-15S appropriate for compact embedded equipment that runs on 15V DC?
It can be used where the product needs a regulated 15V rail and the power draw remains within 3W. The SMD style format and 37.0 × 24.0 × 16.0 mm size support compact internal power sections.
Can this model support small automation, test, or industrial interface modules with 15V requirements?
Yes, for low-power 15V electronics, this model converts 85-305VAC input to a constant 15V output. It is better matched to auxiliary and interface functions than to higher-power 15V loads.
Would the IRM-03-15S work for a small communications or control daughterboard that needs 15V?
It can, as long as the board is designed for 15V constant-voltage input and stays within the 3W rating. Its encapsulated miniature design is intended for internal board-level use.
Can the IRM-03-15S be used in cold or hot equipment environments?
The specified operating temperature range is -30°C to +85°C, which supports a wide range of indoor equipment conditions. No IP rating is listed, so the provided specs do not identify it for exposed outdoor or wet-area use.
How does the IRM-03-15S compare with other 15V models in the series?
For 15V options, IRM-01-15 and IRM-01-15S are 1W, 15V, 0.07A; IRM-02-15 and IRM-02-15S are 2W, 15V, 133A; IRM-03-15 and IRM-03-15S are 3W, 15V, 200A; IRM-05-15 is 4.95W, 15V, 0.33A; IRM-10-15 is 10.05W, 15V, 0.67A; IRM-15-15 is 15W, 15V, 1A; IRM-20-15 is 21W, 15V, 1.4A; IRM-30-15 and IRM-30-15ST are 30W, 15V, 2A; IRM-45-15 and IRM-45-15ST are 45W, 15V, 3A; IRM-60-15 and IRM-60-15ST are 60W, 15V, 4A; and IRM-90-15 and IRM-90-15ST are 85.05W, 15V, 5.67A. The IRM-03-15S is the 3W SMD style option in that 15V lineup.
