Mean Well IRM-01-12S Switching Power Supply 1W 12V 83mA - Encapsulated
Overview
IRM-01-12S is the 12V output model of this series: rated current 83mA, rated power 1W, typical efficiency 74%.
IRM-01 is a 1W miniature (33.7*22.2*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 the fully-potted 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 77% and the extremely low no-load power consumption below 0.075W, IRM-01 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 EN55032 Class B; the supreme EMC features keep the end electronic units from electromagnetic interference. In addition to module-type model, IRM-01 series also offers the SMD style model.

FAQ
Can I use the IRM-01-12S on a compact embedded control board?
Yes, if the board needs constant 12V DC and the total load stays within 1W and 0.08A. Its SMD style and 33.7 × 22.2 × 16.0 mm dimensions make it more appropriate for compact low-power board-level electronics than for larger 12V assemblies.
Is the IRM-01-12S a fit for low-power automation sensing or status modules?
It fits low-power 12V automation or sensing modules that remain under the 0.08A output limit. This model is intended for constant voltage board supply duties rather than higher-current field devices.
Can this SMD model support a small 12V embedded communications or interface circuit?
It can, provided the circuit requires 12V DC constant voltage and does not exceed 1W output. That makes it suitable for light embedded interface, monitoring, or supervisory functions on densely packed electronics.
What is the difference between IRM-01-12S and the other 1W IRM options?
The 1W IRM-01 family is offered in 3.3V 300A, 5V 200A, 9V 111A, 12V 0.08A, 15V 0.07A, and 24V 0.04A versions, with both standard and S variants. This IRM-01-12S keeps the 12V, 1W, 0.08A rating but uses SMD style and a 33.7 × 22.2 × 16.0 mm package, while IRM-01-12 uses PCB mounting style and 33.7 × 22.2 × 15.0 mm dimensions.
Can the IRM-01-12S be used in outdoor equipment or cold and hot enclosures?
Its operating temperature range is -30°C to +85°C, so the temperature specification covers both low and high ambient conditions. No IP rating is listed, so exposure to water, dust, or outdoor conditions is not defined in the provided specs.
