Mean Well IRM-03-15S Switching Power Supply 3W 15V 200mA - Encapsul...
Overview
IRM-03-15S is the 15V output model of this series: rated current 200mA, rated power 3W, typical efficiency 78%. Type S: SMD style.
IRM-03 is a 3W miniature (37*24*15mm) AC-DC module-type power supply, ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipments. This product allows a universal input voltage range of 85~305Vac. The phenolic case and potted with silicone enhance the heat dissipation and meet the anti-vibration demand up to 5G; moreover, it provides the fundamental resistance to dust and moisture. With the high efficiency up to 80% and the extremely low no-load power consumption below 0.075W, IRM-03 series fulfills the worldwide regulation for the low power consumption requirement for electronics. The entire series is a Class Ⅱ design (no FG pin), incorporating the built-in EMI filtering components, enabling the compliance with BS EN/ EN55032 Class B; the supreme EMC features keep the end electronic units from electromagnetic interference. In addition to module-type model, IRM-03 series also offers the SMD style model.

FAQ
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?
Within the IRM-03 series, the 15V output comes in two versions: IRM-03-15 (PCB mounting style, 37 x 24 x 15 mm) and IRM-03-15S (SMD style, 37 x 24 x 16 mm), both rated 3W and 200mA. The series also covers 3.3V, 5V, 9V, 12V and 24V outputs, all at 3W. The IRM-03-15S is the 3W SMD style option in that 15V lineup.
