230 V power supply
Fine in normal use. At full load with USB devices it runs close to the supply's 18 W limit.

Teltonika RUTC40 power supply and cables
Need power for a Teltonika RUTC40? It is a 4G edge router that takes 9 to 50 V DC, and all three of our cables fit its 4-pin socket.
Screw terminal cable
Best for heavy loads: connect to a stronger 24 V DC supply.

Please note
At full load Teltonika measured the Teltonika RUTC40 at 16.2 W on 12 V, close to the 18 W our 230 V supply delivers. Normal use is lower, but if you run USB devices or keep it busy all day, use the screw terminal cable with a stronger 24 V DC supply.
About the Teltonika RUTC40
The RUTC40 is an edge router. Besides 4G Cat 4 with a Telit modem and Wi-Fi 6, it has 1 GB of RAM, a dual-core 1.3 GHz CPU and Docker support, so you can run your own containerised applications on the router itself. That extra computing power shows up in its power figures.
It is used for local data processing, such as reading machines, filtering data and sending only what matters to the cloud.

How much power the RUTC40 draws
Teltonika's power table puts the Teltonika RUTC40 at 3.8 W idle and 16.2 W flat out at 12 V. In current that is about 1348 mA, against the 1500 mA our supply can give.
Which cable should I pick?
- Wall socket. Our 230 V supply works in normal use. For heavy, constant load with USB devices, go for a stronger DC supply instead.
- Vehicle. A quick vehicle install with a fused plug and LED.
- Cabinet, battery or solar. Best for heavy loads: connect to a stronger 24 V DC supply. Add a 2 A slow-blow fuse near the source.
Install tips
- Heavy Docker workloads keep the CPU busy all day. If you plan to run them and power USB devices too, choose a 24 V DC supply with margin and the screw terminal cable.
- The Teltonika RUTC40 is rated to 50 V, which gives good margin on 24 V vehicles. A clean supply is still the best protection against spikes.
- Measure the voltage at the router end once installed, especially with long cable runs on 12 V systems.
Teltonika RUTC40 power FAQ
?What is the input voltage range of the Teltonika RUTC40?
Anything from 9 to 50 V DC on the 4-pin socket. Our 12 V supply, a 24 V truck system or a 48 V DC rail all work.
?I lost the adapter for my Teltonika RUTC40. What do I need?
Any DC supply within 9 to 50 V DC on a Teltonika-style 4-pin plug will work. Our 230 V supply gives 12 V at 1.5 A, which suits the Teltonika RUTC40.
?Is the 18 W power supply enough for the Teltonika RUTC40?
For most installations yes, but it is close at full load. Teltonika measured about 16.2 W at 12 V with the CPU, Wi-Fi, LTE, USB and serial devices all busy. If you run heavy Docker workloads and a USB device, use the screw terminal cable with a stronger DC supply.
?Does the screw terminal cable give access to the Teltonika RUTC40's I/O?
Yes. Only the screw terminal cable connects them. Green goes to the input and white to the output. The car cable and the 230 V supply only use the power pins.
?Is the Teltonika RUTC40 included with the cable?
We do not sell the Teltonika RUTC40. Our shop has three power options for it, and that is all we sell for Teltonika devices.
