Frequently Asked Questions
Can I use the RT-125D for control hardware that needs both 5V and 24V from one supply?
Yes, this version provides 5V, 24V, and 12V outputs in one triple-output unit. That makes it relevant for control hardware where 5V logic and 24V industrial rails need to coexist.
Is the RT-125D suitable for automation systems that combine 24V devices with 5V logic boards?
It can be suitable because the output set includes both 24V and 5V, plus an additional 12V rail. The unit is rated for 136W total power, and the 5V output is rated at 8A.
Can the RT-125D power a compact embedded controller plus 12V and 24V support electronics?
Yes, that is the type of multi-rail arrangement this model addresses because it provides 5V, 12V, and 24V outputs together. Its compact 199.0 x 98.0 x 38.0 mm form factor also helps in enclosed equipment designs.
Would the RT-125D be appropriate in a machine enclosure with vibration and elevated ambient heat?
The listed features include 5G vibration resistance and operation up to 70°C. Its stated operating range is -25°C to +70°C, which supports use in demanding indoor machine environments.
Can the RT-125D be used in outdoor or washdown conditions?
No IP rating is listed in the provided specifications, so it should not be assumed suitable for exposed outdoor or washdown use. The temperature range is -25°C to +70°C, which supports wide-temperature operation when the supply is kept in a protected enclosure.
What sets the RT-125D apart from the other RT-125 models?
RT-125D is the highest-power listed RT-125 version at 136W, and it provides 5V, 24V, and 12V outputs. By comparison, RT-125A is 131W with 5V, 12V, and -5V, RT-125B is 132W with 5V, 12V, and -12V, and RT-125C is 132.5W with 5V, 15V, and -15V; their 5V current ratings are 12A, 12A, and 10A respectively.
