FAQ

Can I use the SMA01N-09 to power a 9V sensing or monitoring circuit inside industrial equipment?

It is intended for constant-voltage 9V output with a 1W power rating, so it fits low-power 9V sensing, monitoring, or interface circuits that stay within that 1W limit. The input range is 21.6~26.4V and the package is compact at 12.7 x 10.16 x 7.62 mm for tight embedded designs.

Is the SMA01N-09 a fit for 24V-class control systems that need a small 9V rail?

The specified input range is 21.6~26.4V, which aligns with equipment operating in that range and needing a regulated 9V output. With only 1W available, it is better suited to low-power control, signal, or embedded loads rather than larger 9V devices.

Can this converter be used in compact embedded automation boards with very limited space?

Yes, the body size is 12.7 x 10.16 x 7.62 mm and the weight is 0.0017 kg, so it is designed for very space-constrained boards or modules. Its constant-voltage 9V output also makes it appropriate where the downstream circuit expects a fixed 9V rail within the 1W limit.

How does the SMA01N-09 compare with other SMA01N models?

In the SMA01N series, SMA01N-05 is 1W with 5V and 200mA output, SMA01N-09 is 1W with 9V and 110mA output, SMA01N-12 is 1W with 12V and 84mA output, and SMA01N-15 is 1W with 15V and 67mA output. This model is the 9V version for applications that need a 21.6~26.4V input and constant-voltage output.

Is the SMA01N-09 suitable for outdoor or harsh-temperature use?

Its operating temperature range is -40C to +90C, which supports very cold and very hot environments from a temperature standpoint. However, no IP rating is listed in the provided specs, so exposed outdoor or washdown suitability cannot be confirmed from this data alone.
