The Foundation for Stability: Original Teltonika 4-Pin Power Supply
In critical M2M and IoT applications, failure is not an option. While many consider a Power Supply a simple accessory, it is in fact the foundation for the stability of your entire system. The PR3PUEU3 is the original Power Supply developed and certified by Teltonika, precisely matched to the electrical requirements of the RUT2XX and TRB1XX series. Unlike cheap universal power supplies, it delivers a clean and stable voltage without dangerous spikes that can damage sensitive electronics or lead to unexplained system crashes. Rely on the original to ensure maximum lifespan and reliability of your Teltonika 4G / 5G Routers.
Why the Original Power Supply is Crucial for Your RUT240
The difference is in the details – and with the PR3PUEU3, it's the 4-pin connector. This industrial connector offers much more than a conventional barrel connector. It is firmly screwed to the router, creating a vibration-proof, locked connection that makes accidental disconnection of the power supply impossible. This is essential in vehicles, control cabinets, or other moving environments. Furthermore, the connector transmits not only the power supply (Pin 1 & 2) but also programmable I/O signals (Pin 3 & 4). This allows you to monitor external sensors or switch actuators – a functionality that can only be fully utilized with the original Industrial Power Supply 9V 1A.
For 24/7 Continuous Operation: Robust Technology in Detail
Teltonika devices are designed for tireless continuous use, and their Accessories must meet this demand. The PR3PUEU3 power supply is designed for extremely high durability with a Mean Time Between Failures (MTBF) of up to 50,000 hours. Integrated short-circuit protection circuits safeguard both the power supply and your router. With comprehensive safety certifications such as IEC/EN 62368-1 and a high dielectric strength of up to 4242 VDC between primary and secondary sides, you can rely on this power supply to operate safely and reliably even under demanding conditions.
Compatibility and Use: Which Devices is the PR3PUEU3 Suitable For?
This 9W power supply is the official standard power supply and the perfect choice for the energy-efficient devices of the Teltonika RUT2XX series (e.g., RUT240, RUT241) and the TRB1XX gateway series (e.g., TRB140, TRB141, TRB142, TRB145). It serves as a perfect replacement power supply or as a power supply for devices delivered without one. Important note: For more powerful series like RUT9XX or RUTX, this power supply is undersized. These require more powerful PoE Injectors / Power Supplies with at least 18W to guarantee stable operation under full load. You can also find the appropriate Teltonika Accessories with us.

Frequently Asked Questions (FAQ)
Is this power supply compatible with the Teltonika RUT955?
No, the PR3PUEU3 (9V/1A, 9W) is not officially recommended for the RUT955. For the RUT955 and other models of the RUT9XX series, a more powerful power supply of at least 18W is strongly recommended to ensure stable operation.
Why does the power supply have a 4-pin connector and not a normal round connector?
The 4-pin connector is an industry standard that creates a secure, lockable connection, preventing accidental disconnection. Additionally, programmable Input/Output (I/O) signals can be transmitted via this connector, which can be used for many M2M and IoT applications.
Can I use any 9V power supply for my Teltonika Router?
This is not recommended. The original power supply is tested to prevent voltage fluctuations and spikes, which can damage the router or cause reboots with cheap universal power supplies. Using the original power supply is essential for maximum stability and reliability.
What does the efficiency standard 'DoE Level VI' mean?
'DoE Level VI' is a high US standard for energy efficiency. It guarantees very low power consumption in idle mode and high efficiency during operation, which saves electricity and reduces heat generation.
Is the power supply suitable for outdoor use?
No, the power supply is explicitly designed for indoor use and is not protected against moisture, rain, or extreme temperatures.
Which devices are typically shipped with this power supply?
The PR3PUEU3 is the standard power supply shipped with many devices from the RUT2XX series (e.g., RUT240, RUT241) and the TRB1XX series (e.g., TRB140, TRB142, TRB145).
