FAQ
Can I use the SUS01O-12 for a low-power 12V control circuit in industrial equipment?
Yes, it is intended for applications that need a 12V constant-voltage output from a 43.2~52.8VDC input range. With a 1W power rating and 84mA output current, it is best suited to low-power control electronics.
Is this a good choice for embedded 12V auxiliary power inside compact devices?
It can fit embedded 12V auxiliary power roles where the load stays within 1W. The 22.6 × 9.9 × 8.9 mm package is useful when board or enclosure space is tight.
Can the SUS01O-12 be used for small automation interface modules that need 12V?
It is suitable for small automation interface modules that require a fixed 12V output and operate from 43.2~52.8VDC input. The 84mA output rating indicates it is aimed at light electronic loads rather than larger 12V devices.
Is the SUS01O-12 intended for indoor-only use, or can it handle exposed environments?
The stated operating temperature range is -25°C to +71°C, so the product has a defined thermal envelope for equipment use. No IP rating is listed, so the specifications do not confirm suitability for exposed outdoor environments.
What should I compare between the SUS01O-12 and the other SUS01O models?
The listed SUS01O family members all share 1W power, 43.2~52.8VDC input, and 22.6 × 9.9 × 8.9 mm dimensions, while the outputs differ: SUS01O-05 is 5V and 200mA, SUS01O-09 is 9V and 111mA, SUS01O-12 is 12V and 84mA, and SUS01O-15 is 15V and 67mA. The practical distinction is the output voltage and associated output current spec for each version.
