FAQ

Can I use the SUS01O-09 for a 9V rail in embedded or industrial electronics powered from 43.2~52.8VAC?

Yes, this unit is intended for 43.2~52.8VAC input applications that need a regulated 9V constant-voltage output. Its 1W rating makes it more appropriate for low-power embedded or industrial electronics than for higher-demand devices.

Is the SUS01O-09 suitable for low-power automation sensors or interface circuits that require 9V?

It can be used for low-power automation sensors or interface circuits that need a stable 9V supply and stay within the 1W rating. The compact 22.6 × 9.9 × 8.9 mm size also supports use in space-constrained assemblies.

Would this converter make sense for small 9V control sections inside equipment cabinets?

Yes, it is suited to small 9V control sections inside equipment cabinets when the source falls in the 43.2~52.8VAC range. The constant-voltage output is intended for electronics that expect a fixed 9V rail.

Can this model be used in outdoor automation equipment?

The datasheet details an operating temperature range of -25°C to +71°C, which covers its stated thermal operating limits. Since no IP rating is shown, the listing does not establish outdoor or direct-exposure suitability.

How does the SUS01O-09 differ from the other SUS01O output variants?

All listed SUS01O siblings are 1W converters with 43.2~52.8VAC input and 22.6 × 9.9 × 8.9 mm dimensions, but they provide different outputs: SUS01O-05 is 5V and 200A, SUS01O-09 is 9V and 111A, SUS01O-12 is 12V and 0.08A, and SUS01O-15 is 15V and 0.07A. Selection within the group comes down to the required output voltage and its matching current spec.
