Frequently Asked Questions
Can I use the RD-85A for a larger industrial control system with 5V logic and 12V auxiliary loads?
Yes, this dual output constant voltage model is rated for 88W total and provides a 5V output rated at 8A. That gives it more 5V current headroom than the 50W and 65W siblings. It is therefore better suited to larger control assemblies that still require regulated 5V along with a 12V rail.
Is the RD-85A suitable for embedded computing, industrial PCs, or HMI systems with higher 5V demand?
It can be a strong fit where the main requirement is a 5V constant voltage rail up to 8A. The 88W power rating places it above the lower-power RD models, which helps when the 5V load is heavier. Its 88-264VAC input also supports use in equipment intended for different AC supply ranges.
Can the RD-85A be used in machinery or automation equipment subject to vibration and heat?
This model is specified to withstand 5G vibration and to operate up to +70C, with a full operating range of -25C to +70C. Those specs make it suitable for industrial environments where enclosure temperature and vibration are selection factors. Its 5V 8A main output and 88W total rating should still be matched to the actual system load.
Is the RD-85A intended for indoor or outdoor applications?
The stated operating temperature range is -25C to +70C, which supports many indoor industrial environments. No IP rating is given in the supplied specs, so it should be treated as a unit for protected indoor use or installation inside suitable equipment enclosures rather than exposed outdoor use. Temperature capability alone does not make it outdoor rated.
What is the RD-85A's position relative to other RD series models?
In the sibling list with provided figures, RD-35A is 32W at 5V 4A, RD-35B is 35W at 5V 2.2A, RD-50A is 54W at 5V 6A, RD-50B is 53.6W at 5V 4A, RD-65A is 66W at 5V 6A, RD-65B is 68W at 5V 4A, RD-85B is 88W at 5V 8A, RD-125A is 130.9W at 5V 7.7A, RD-125B is 133.4W at 5V 4.6A, RD-3513 is 35.1W at 13.5V 1.3A, RD-125-1224 is 125W at 12V 3.7A, RD-125-1248 is 125W at 12V 2.3A, and RD-125-2448 is 125W at 24V 2A. The sibling list also names RD-125-2412, RD-125-4812, RD-125-4824, RD-125A-OB, RD-125NB, and RD-65A-OB without full numerical specs. RD-85A is the 88W, 5V 8A model in this set.
