Frequently Asked Questions
Can I use the IRM-01-3.3 for a 3.3V microcontroller or embedded logic board?
Yes, this model is aimed at low-power 3.3V electronics where 1W is enough. With a 3.3V constant voltage output and 1W rating, it fits embedded control, sensing, or monitoring boards that need direct AC-to-DC conversion on the PCB.
Is the IRM-01-3.3 a good fit for industrial monitoring or IoT nodes running at 3.3V?
It can be a fit for compact industrial or embedded nodes that operate from 3.3V and stay within the 1W limit. The 85-305VAC input range is useful when the source side may vary across common AC line conditions.
Can this model power a small 3.3V sensor-processing or communication circuit?
Yes, if the circuit is a low-consumption 3.3V DC load and the total demand remains within the 1W output rating. This makes more sense for compact logic, sensing, or communications sections than for anything with a larger power draw.
Is the IRM-01-3.3 suitable for indoor control panels or outdoor equipment?
Its operating temperature range is -30°C to +85°C, which supports use across a broad temperature window. No IP rating is listed, so it is better treated as an internal encapsulated module for protected enclosures rather than exposed outdoor service.
What are the main output options around the IRM-01-3.3 in the IRM family?
In the 1W IRM-01 range, the related models are 3.3V 300A, 5V 200A, 9V 111A, 12V 0.08A, 15V 0.07A, and 24V 0.04A, with standard and S versions across several voltages including IRM-01-3.3S. Above that, IRM-02 through IRM-90 siblings expand the series from 2W to 90.2W and cover outputs from 3.3V up to 48V.
