Frequently Asked Questions
Can I use the SPAN02A-03 to power 3.3V embedded control electronics?
It is suited to low-power embedded or industrial logic circuits that need a regulated 3.3V output from a 9-18VAC input source. With a 2W constant-voltage rating, it is intended for small electronics and control sections within that power level.
Is this a good fit for a 3.3V sensor or communications module in automation equipment?
Yes, when the module requires 3.3V constant voltage and the available input is within 9-18VAC. The 2W rating and compact 21.8 × 11.1 × 9.2 mm size make it more appropriate for low-power sensing, telemetry, or interface circuits.
Would the SPAN02A-03 work in a low-voltage control panel with a 3.3V logic rail?
It can fit low-voltage control designs that have a 9-18VAC source and need a dedicated 3.3V rail. The listed output current is 500A and the converter operates in constant-voltage mode.
Can this model support compact industrial IoT or monitoring hardware?
It is relevant for compact monitoring or embedded hardware that uses 3.3V and stays within the converter's 2W capacity. Its 0.0048 kg weight and small form factor are also useful where space is limited.
Is the SPAN02A-03 intended for indoor or outdoor environments?
The operating temperature range is -40°C to +90°C, which supports use across a wide set of temperature conditions. An IP rating is not provided in the specs, so outdoor or sealed-enclosure suitability is not defined here.
How does the SPAN02A-03 differ from the other SPAN02A models?
The SPAN02A-03, SPAN02A-05, SPAN02A-12, and SPAN02A-15 all have 2W power, 9-18VAC input, 21.8 × 11.1 × 9.2 mm dimensions, 0.0048 kg weight, and a -40°C to +90°C operating range. The outputs differ: 3.3V with listed 500A, 5V with listed 400A, 12V with listed 167A, and 15V with listed 134A.
