Teltonika PR3P2US3 US 24 W Power Supply for RUTX12 Dual-Modem Router

Teltonika's RUTX12 pairs two full cellular modems in one chassis, and its power budget reflects that: the router calls for a 24 W supply, noticeably more than the adapters shipped with single-modem RUT models. The PR3P2US3 is the US-plug version of that 24 W supply — the part to order when an original adapter goes missing, fails, or when you want a spare per site as cheap insurance against downtime. The distinction from the PR315PS3 is simple: same 24 W rating, but this unit carries a fixed US wall plug rather than the universal multi-region format. For US-only estates that makes it the tidier choice — nothing to assemble, nothing to lose. Why insist on the rated supply? Dual-modem routers have spiky power profiles. Both radios keying up at once — a routine event when the RUTX12 load-balances two carriers — produces a transient draw that an under-rated adapter cannot hold, and the resulting brownout looks like a mysterious spontaneous reboot. Sites burn hours chasing firmware ghosts that are actually power problems. A factory 24 W unit closes that door. At about 0.30 lb, the PR3P2US3 is easy to stock in quantity. Fleet operators running RUTX12 failover or dual-carrier load balancing should treat power supplies as consumables and keep at least one spare per ten routers deployed; it is the cheapest component in the stack and the most common one to fail or wander off.
