Frequently Asked Questions
Can I use the RT-125C for industrial or embedded equipment that needs 5V and ±15V rails?
Yes, this model provides 5V, 15V, and -15V outputs from one unit. That output combination is relevant for embedded and industrial electronics that need both a 5V logic rail and symmetrical 15V rails.
Is the RT-125C suitable for analog signal-conditioning or instrumentation circuits?
It can be a good fit where the electronics need 5V plus 15V and -15V rails. The total power rating is 132.5W, and the 5V output is rated for 10A.
Can the RT-125C support mixed digital and analog boards in one enclosure?
Yes, the output set of 5V, 15V, and -15V is useful when one enclosure contains both logic and analog sections. Its triple-output design reduces the need to source those rails from separate power supplies.
Would the RT-125C work in compact automation hardware that sees vibration and wide indoor temperature variation?
The unit is specified for -25°C to +70°C operation, and the features list includes 5G vibration resistance. Its 199.0 x 98.0 x 38.0 mm dimensions also suit space-conscious industrial hardware builds.
Is the RT-125C intended for outdoor environments?
The temperature range is broad at -25°C to +70°C, but no IP rating is provided in the product data. That means it is best treated as a supply for protected indoor locations or enclosed equipment rather than exposed outdoor use.
How does RT-125C differ from the other RT-125 power supplies?
RT-125C is the 132.5W model with 5V, 15V, and -15V outputs and a 5V current rating of 10A. The other listed RT-125 versions are RT-125A at 131W with 5V, 12V, and -5V, RT-125B at 132W with 5V, 12V, and -12V, and RT-125D at 136W with 5V, 24V, and 12V.
