Frequently Asked Questions
Can I use the SUS01L-12 to generate 12V for a compact industrial control or embedded board?
Yes, this unit provides constant 12V output from a 4.5~5.5V input range and is intended for low-power conversion tasks. Its 1W rating makes it suitable for small control, monitoring, or embedded subcircuits rather than heavier 12V loads.
Is the SUS01L-12 a fit for low-power automation interface circuits that need a regulated 12V rail?
It can be used where the input source is 4.5~5.5V and the downstream 12V section stays within the 1W limit. The converter's constant-voltage mode is appropriate when the load expects a fixed 12V output.
Can this model work in compact instrumentation or portable electronics that need a small 12V supply stage?
Yes, its 22.6 × 9.9 × 8.9 mm dimensions support use in space-constrained electronics. With a weight of 0.0031 kg, it also fits small assemblies where component size matters.
What is the difference between the SUS01L-05, SUS01L-09, SUS01L-12, and SUS01L-15 models?
All four are 1W converters in the same series. The sibling outputs are SUS01L-05 at 5V and 200A, SUS01L-09 at 9V and 111A, SUS01L-12 at 12V and 0.08A, and SUS01L-15 at 15V and 0.07A.
Is the SUS01L-12 suitable for outdoor or harsh-environment use?
The specified operating temperature is -25°C to +71°C, which supports a broad indoor equipment range. Since no IP rating is listed, it is better treated as a converter for protected enclosures rather than exposed outdoor mounting.
