Frequently Asked Questions
Can I use the RPS-120S-48 for a 48V industrial controller or automation node?
Yes, this is a constant voltage 48V power supply rated for 2.5A and 120W. It is appropriate for 48V DC equipment that stays within those output limits.
Is the RPS-120S-48 suitable for embedded systems that use a 48V DC bus?
It can be a fit for compact embedded platforms that are designed around a 48V rail. The supply provides regulated 48V output and uses a 76.2 x 50.8 x 28.0 mm footprint for space-constrained designs.
Can this 48V model support loads with brief inrush or transient demand?
Yes, it provides 120W continuous output and supports 150W peak for 10s. That is useful when a 48V load briefly rises above its normal running level.
Is the RPS-120S-48 meant for outdoor operation?
This unit does not list an IP rating, so it is better used inside equipment or in a protected enclosure rather than in exposed outdoor conditions. Its operating temperature range is -30°C to +85°C, which supports demanding thermal environments when the installation is sheltered.
What are the key differences between the RPS-120S-48 and the other RPS-120S outputs?
In the RPS-120S family, the outputs are 12V at 9.5A and 114W, 15V at 7.6A and 114W, 24V at 5A and 120W, 27V at 4.44A and 119.9W, and 48V at 2.5A and 120W. The 48V model provides the highest output voltage in this group with the corresponding lower current rating.
