FAQ
Can I use the SPU03L-05 to generate 15V for a low-power embedded or control circuit from a 4.5~5.5V source?
No, this converter is designed to provide a 5V constant-voltage output from a 4.5~5.5V input range. Its 3W rating makes it suitable for low-power embedded, control, and interface electronics that need a regulated 5V rail from a 5V source.
Is the SPU03L-05 appropriate for small industrial or automation subsystems that need a 15V rail?
It can fit low-power industrial or automation electronics that require 5V and remain within the unit's 3W rating. The constant-voltage output is appropriate for regulated electronic loads rather than applications that need larger power capacity.
Would the SPU03L-05 work for compact board-level designs where available space is tight?
Yes, the converter measures 19.6 × 7.5 × 10.2 mm and weighs 2.9g. That compact size makes it suitable for embedded and automation boards that need a 5V rail from a 4.5~5.5V input.
Can this model be used in equipment that sees elevated or below-freezing temperatures?
The specified operating temperature range is -40°C to +90°C. That supports use in low-power electronics across a broad range of indoor industrial and embedded temperature conditions.
How does the SPU03L-05 compare with the other SPU03L versions?
The SPU03L family is rated at 3W and uses the same 19.6 × 7.5 × 10.2 mm package. In the provided sibling list, SPU03L-12 is listed as 12V with 25~250mA and SPU03L-15 is listed as 15V with 20~200mA, while this model outputs 5V.
Is the SPU03L-05 intended for indoor or outdoor conditions?
Its operating temperature range is -40°C to +90°C, but no IP rating is provided in the listed specs. Based on the published information, temperature limits are defined, while direct outdoor exposure is not specifically rated.
