Frequently Asked Questions
Can I use the SRS-1212 to maintain a regulated 12V rail from a 10.8~13.2V source in industrial electronics?
Yes, it is specified for 10.8~13.2V input and provides a constant 12V output. Its 0.5W rating and 0.04A output current make it suitable for low-power industrial or embedded support rails rather than higher-current 12V loads.
Is the SRS-1212 a good fit for small automation, PLC-adjacent, or monitoring circuits that need light 12V power?
It can fit those low-demand applications when the load stays within 0.04A at 12V and within the 0.5W limit. The constant-voltage output is better matched to auxiliary electronics than to larger actuators or other heavier 12V devices.
Can the SRS-1212 be used in tightly packed embedded assemblies?
The module measures 22.6 × 9.9 × 8.4 mm and weighs 0.0031 kg, so it is intended for compact board-level designs. That makes it practical where a small regulated 12V rail is needed from a 10.8~13.2V input window.
Is the SRS-1212 suitable for indoor-only use, or can it go outdoors?
The published operating range is -25°C to +71°C, but the provided specs do not include an IP rating. On that basis, it is better aligned with protected indoor assemblies or sealed equipment interiors than direct outdoor exposure.
How does the SRS-1212 compare with the rest of the SRS series?
The sibling list keeps all models at 0.5W, but the available outputs are 5V, 9V, 12V, and 15V with different listed currents. The listed group is SRS-0505, SRS-1205, SRS-2405, and SRS-4805 at 5V with listed 100A; SRS-0509, SRS-1209, SRS-2409, and SRS-4809 at 9V and 0.06A; SRS-0512, SRS-1212, SRS-2412, and SRS-4812 at 12V and 0.04A; and SRS-0515, SRS-1215, SRS-2415, and SRS-4815 at 15V and 0.03A.
