What this adapter is and who it is for

The Graviton TPN-LA10 is a 230 W AC power adapter that delivers 19.5 V at 11.8 A through a 7.4 mm by 5.0 mm barrel connector. It is built for HP mobile workstations such as the 8740w, 8560 and ZBook 17 models that require this exact voltage, current and tip size.

Check your existing setup before ordering

Confirm that the laptop you intend to power lists a 19.5 V 11.8 A 230 W requirement and uses a 7.4*5.0 mm DC jack. Verify the unit you are replacing carries the TPN-LA10 part number. The adapter accepts 100 to 240 V AC input at 50 to 60 Hz, so it works on mains supplies worldwide without a voltage switch.

Thermals noise and power draw in normal use

The brick is rated for a continuous 230 W DC output and draws its power from a 100 to 240 V AC line at 50 to 60 Hz. No fan or active cooling is mentioned in the specifications, so operation is silent. Heat output will scale with the load placed on the adapter by the connected workstation.
