Teltonika PR3PRUS6 US 2-Pin 9 W Power Supply for TRB245 and TRB255 Gateways

Teltonika's TRB245 and TRB255 gateways bring cellular connectivity, serial ports and I/O to compact industrial installations, and they sip power — 9 W covers them with margin. The PR3PRUS6 is the matching factory supply for the US market: a 2-pin wall-plug adapter delivering the specified 9 W to either gateway. The usual reasons to order one: the original adapter stayed behind at a decommissioned site, a bench needs dedicated power for staging and firmware work, or an installation calls for AC wall power rather than the hardwired DC these gateways often run on in panels. Because TRB-series devices frequently move between bench and field during commissioning, teams standardizing on a couple of spare PR3PRUS6 units avoid the perennial hunt for the right adapter. Rating discipline matters even at the small end of the range. A gateway's cellular radio produces short transmit-current peaks, and no-name adapters with optimistic labels can dip under that load, resetting the device mid-session — a frustrating fault to chase when it happens only during heavy uplink. The factory 9 W unit is sized for those peaks. At roughly 0.22 lb, the adapter adds nothing to a commissioning kit. Note that it is matched to the TRB245/TRB255 pair; other Teltonika families use different supplies (9 W RUT-series units use a different part, and RUTX routers require 18-24 W). Keep part numbers straight and the fleet stays predictable.
