Frequently Asked Questions
Can I use the RPS-45-3.3 for a 3.3V embedded controller or single-board computer inside industrial equipment?
Yes, this model is a constant-voltage 3.3V supply rated for up to 8A and 26.4W. That makes it suitable for 3.3V embedded control hardware as long as the total load stays within those output limits.
Is the RPS-45-3.3 suitable for powering 3.3V logic boards in medical or laboratory devices?
It can fit 3.3V logic and control sections that need a regulated 3.3V output with up to 8A available. This model is medical safety approved and also features extremely low leakage current, which is relevant for medical and lab equipment designs.
Can this 3.3V power supply run low-voltage automation electronics in a compact enclosure?
Yes, it is intended for constant-voltage 3.3V loads and is rated at 26.4W. Its 76.2 x 50.8 x 24.0 mm size and 0.11 kg weight help when space is limited inside compact automation assemblies.
Is the RPS-45-3.3 a good fit for 3.3V sensor hubs or interface boards that need higher current than small board supplies provide?
It is a stronger option when the load needs 3.3V at up to 8A, which is more current than many small board-level supplies provide. Buyers should size the load against the 26.4W maximum output rather than voltage alone.
How does the RPS-45-3.3 compare with other RPS-45 models?
Within the RPS-45 group, the sibling models are RPS-45-5 at 40W, 5V, 8A; RPS-45-7.5 at 40.5W, 7.5V, 5.4A; RPS-45-12 at 45.6W, 12V, 3.8A; RPS-45-15 at 45W, 15V, 3A; RPS-45-24 at 45.6W, 24V, 1.9A; and RPS-45-48 at 45.1W, 48V, 0.94A. The RPS-45-3.3 is the 3.3V version and is rated for 26.4W at 8A.
Can the RPS-45-3.3 be used in outdoor or harsh-temperature locations?
The operating temperature range is -30C to +70C, so it can handle a wide temperature span inside protected equipment. No IP rating is listed, so it is better suited to indoor or enclosed use rather than exposed outdoor locations.
