FAQ

Can I use the SUS01N-05 to derive 5V for embedded logic from a 21-26VAC control source?

Yes, this model is intended for converting a 21-26VAC input to a constant 5V output for low-power electronics. It is rated at 1W total, so it fits light embedded logic, monitoring, or interface loads rather than larger 5V systems. Buyers should verify that both the source range and the load fit the listed specifications.

Is the SUS01N-05 suitable for low-power 5V automation electronics in compact equipment?

It can be suitable when the automation electronics need a constant 5V rail from a 21-26VAC input source and stay within the 1W power rating. The package size is 22.6 × 9.9 × 8.9 mm, which helps in compact equipment layouts. This makes it more appropriate for small electronics than for heavier 5V loads.

Can this converter be used in industrial monitoring or communication subcircuits that run on 5V?

It can be used for low-power 5V monitoring or communication subcircuits when the upstream supply is within 21-26VAC. The output mode is constant voltage, which is appropriate for electronics expecting a regulated 5V rail. Its 1W rating defines it as a small auxiliary power solution, not a general-purpose 5V supply for larger devices.

Is the SUS01N-05 designed for outdoor use or only protected environments?

The published specs include an operating temperature range of -25°C to +71°C, but they do not include an IP rating. That means temperature capability is stated, while water and dust protection are not. Based on the provided information, it should be treated as a component for protected enclosures rather than exposed outdoor use.

How does the SUS01N-05 compare with the other SUS01N outputs?

The listed siblings are SUS01N-09 at 1W and 9V with 111A, SUS01N-12 at 1W and 12V with 0.08A, and SUS01N-15 at 1W and 15V with 0.07A. The SUS01N-05 version is the 5V member and is also rated at 1W, with a listed output current of 200A. The series differences are the output voltage and listed output current while keeping the same 1W family format.
