Teltonika RUT951 power supply and cables
Everything about powering the Teltonika RUT951, a four-port 4G router: the voltage it accepts, its real power draw and the cables that fit.

Please note
The Active PoE version of the RUT951 (product code RUT951*1****) has a 9 to 57 V range over PoE and no pins 3 and 4 on the power socket. Our cables still power it through pins 1 and 2.
About the Teltonika RUT951
The RUT951 is the current four-port, dual-SIM RUT9 router and the natural step up from a RUT950. Teltonika also makes it in an Active PoE version, and that detail matters for power: the PoE version has a different input range and drops the input and output on pins 3 and 4.
It is a popular pick for retail sites and small branch offices that want failover between two operators.

How much power the RUT951 draws
On 12 V, the Teltonika RUT951 draws about 351 mA at its busiest, or 4.2 W. Left idle it sits near 1.1 W. Our 230 V supply is rated 1.5 A, so the router uses roughly 23% of it at peak. On a 24 V supply the peak is about 4.7 W.
Which cable should I pick?
- Wall socket. A replacement for the original adapter, with 13.8 W of spare capacity.
- Vehicle. Quick vehicle install. Fine on 12 V and 24 V systems.
- Cabinet, battery or solar. Bare ends for a DC rail or battery. Green and white are the I/O pins (not on Active PoE units). Add a 2 A slow-blow fuse near the source.
Install tips
- Check the product code on the label before you wire I/O. On Active PoE units Teltonika lists pins 3 and 4 as not present, so any input or output wiring there does nothing.
- On 24 V vehicles, add surge protection. Truck and bus systems can spike well above 30 V at engine start, and the Teltonika RUT951 is only rated to 30 V.
- Fit a fuse near the battery when you use the screw terminal cable on 12 V. Our FAQ suggests a 2 A slow-blow fuse.
Teltonika RUT951 power FAQ
?Can I run the Teltonika RUT951 on 12 V or 24 V?
Yes, both. The input range is 9 to 30 V DC, fed through the 4-pin power socket.
?I lost the adapter for my Teltonika RUT951. What do I need?
Any DC supply within 9 to 30 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 RUT951.
?I have the Active PoE version of the Teltonika RUT951. Do your cables fit?
They plug into the same 4-pin socket and carry power on pins 1 and 2, so the router will power up. On the Active PoE version the input and output pins do not exist, so the green and white wires of the screw terminal cable have nothing to connect to.
?Does the screw terminal cable give access to the Teltonika RUT951's I/O?
On the standard Teltonika RUT951, green is the input and white the output. On the Active PoE version those pins are not present, so leave the two wires unconnected and insulated.
?How much headroom does the Teltonika RUT951 leave on an 18 W supply?
Plenty. At 4.2 W peak, the Teltonika RUT951 uses 23% of 18 W.
?Does Smart Power Cable sell Teltonika routers?
Not the router, no. We are an independent maker of power cables. The Teltonika RUT951 is a Teltonika product sold through their own channels.
