Frequently Asked Questions
Can I use the SPAN02A-05 for 5V embedded or industrial control electronics?
It can be used for low-power embedded, monitoring, or control circuits that need 5V constant voltage from a 9-18VAC input source. The converter is rated at 2W, so it is best matched to smaller electronics within that power budget.
Is this converter suitable for a 5V sensor hub or small automation interface?
Yes, if the interface needs a regulated 5V output and the source is within 9-18VAC. The compact 21.8 × 11.1 × 9.2 mm package supports dense layouts in control or embedded assemblies.
Would the SPAN02A-05 fit a low-power 5V communications or telemetry module?
It is intended for constant-voltage 5V applications and has a 2W rating with listed 400A output current. That makes it a better fit for low-power communications, telemetry, or logic circuits than for larger 5V loads.
Can this model be used in compact monitoring equipment with a low-voltage AC source?
It can fit monitoring or embedded equipment when the available input is 9-18VAC and the electronics need 5V output. Its 0.0048 kg weight and small dimensions help where board area and component mass are constrained.
Is the SPAN02A-05 appropriate for outdoor or high-temperature locations?
The specified operating range is -40°C to +90°C, so it supports a wide temperature range. No IP rating is listed, so the provided data does not define outdoor, wet-location, or dust-tight suitability.
What are the differences between the SPAN02A-05 and the other 2W models in the same series?
All SPAN02A siblings share 2W power, 9-18VAC input, 21.8 × 11.1 × 9.2 mm dimensions, 0.0048 kg weight, and -40°C to +90°C operation. Their output options are 3.3V with listed 500A for SPAN02A-03, 5V with listed 400A for SPAN02A-05, 12V with listed 167A for SPAN02A-12, and 15V with listed 134A for SPAN02A-15.
