Frequently Asked Questions
Can I use the SPAN02B-05 to power 5V embedded controllers from a higher-voltage control supply?
Yes, it is intended for low-power 5V electronics that need constant voltage output from an 18-36VAC input range. The 2W rating makes it a fit for embedded controllers, interface boards, and similar low-power circuits.
Is the SPAN02B-05 suitable for industrial sensor or communication modules that run on 5V?
It can be used where a regulated 5V rail is needed and the source is within 18-36VAC. With constant voltage operation and a 2W output rating, it aligns with low-power sensor, signaling, and communication electronics.
Can this model be used in automation boards where space is very limited?
Yes, its 21.8 × 11.1 × 9.2 mm dimensions and 0.0048 kg weight support use in tightly packed automation boards. That small footprint is useful when adding a dedicated 5V rail inside compact equipment.
Is the SPAN02B-05 appropriate for low-power HMI or control-panel electronics?
It is appropriate for low-power panel electronics that require a steady 5V output and fit within the 2W rating. The 18-36VAC input range makes it suitable for systems built around higher-voltage control power.
What are the differences between the SPAN02B-05 and the other SPAN02B versions?
All listed SPAN02B models are rated at 2W, but their outputs differ. The range includes SPAN02B-03 at 3.3V and 500A, SPAN02B-05 at 5V and 400A, SPAN02B-12 at 12V and 167A, and SPAN02B-15 at 15V and 134A.
Can the SPAN02B-05 be used in outdoor control boxes or harsh environments?
The converter is rated for -40°C to +90°C operation, which covers a wide temperature range for industrial equipment. No IP rating is listed, so the provided specs do not confirm outdoor exposure or washdown suitability.
