Flexible Voltage Options for Every Setup

One size does not fit all, and the RT-125 series solves that problem. You can pick the exact voltage combination your project needs without carrying extra units. The RT-125A gives you 5V, 12V, and -5V. The RT-125B provides 5V, 12V, and -12V. The RT-125C offers 5V, 15V, and -15V. The RT-125D delivers 5V, 24V, and 12V. This variety means fewer stock parts to manage and faster job completion.

Easy to Mount and Wire

Installers appreciate tools and gear that work the way they expect. The RT-125 slides right onto standard DIN rails and stays secure during transport or operation. Clear screw terminals make connections fast and reliable, even in tight panels. The compact metal housing keeps heat low and efficiency high, so your power supply runs cool and lasts longer. It also handles a wide input voltage range, so you do not have to worry about minor fluctuations in your site power.

Built-In Protection for Peace of Mind

Sensitive electronics need steady power, and the RT-125 delivers exactly that. Each model includes short circuit, overload, and overvoltage protection. If a fault occurs, the unit safely shuts down or limits output to keep your connected devices safe. This reliability reduces callback visits and protects your reputation. You get consistent performance day after day, even in demanding environments.
