FAQ
Can I use the SUS01N-12 to generate 12V for low-power industrial control circuits from a 21-26VDC source?
Yes, it is suited to low-power 12V control electronics when the input source falls within 21.6-26.4VDC. The output is constant voltage at 12V, and the unit is rated for 1W with a maximum output current of 84mA. That makes it better for small auxiliary control loads than for higher-draw 12V equipment.
Is the SUS01N-12 appropriate for compact embedded systems that need an isolated 12V auxiliary rail?
It can be appropriate for very small embedded systems that need a regulated 12V auxiliary supply from a 21.6-26.4VDC input. The package measures 22.6 × 9.9 × 8.9 mm and weighs 3.1g, which is useful in space-limited designs. The load should remain within the 1W and 84mA limits.
Can this model power low-current 12V automation interfaces or signaling electronics?
It can power 12V automation interfaces or signaling electronics that require constant-voltage output and draw no more than 84mA. Because the total power rating is 1W, it is intended for light auxiliary electronics rather than larger field devices or actuators. It is important to match both voltage and power demand to the listed specs.
Is the SUS01N-12 suitable for outdoor cabinets or only indoor protected enclosures?
The datasheet information provided includes an operating temperature range of -25°C to +71°C, so temperature capability is stated. However, no IP rating is listed, so the product's resistance to rain, washdown, or dust ingress is not defined here. Based on the available specs, it is safer to classify it for protected enclosure use unless separate enclosure data is provided.
How does the SUS01N-12 compare with the other SUS01N options?
The sibling models listed are SUS01N-05 at 1W and 5V with 200mA, SUS01N-09 at 1W and 9V with 111mA, and SUS01N-15 at 1W and 15V with 67mA. The SUS01N-12 itself is a 1W, 12V model with 84mA output current. All belong to the same 21.6-26.4VDC input family, with output voltage and listed current being the main differentiators.
