TV One's 5V DC Power Supply with Locking Connector can be used to power many different TV One devices that work on 5 volts of power. Some examples include the 1T-VS-626 HDMI Scaler, any 5 volt 1-T-CT series Transmitters and Receivers, and any 5 volt 1T-DA series Distribution Amps.
The power supply features AC power on the wall end and DC power on the other end. The DC end, once plugged into a device, can be slightly turned to lock inside the device so as to protect against accidental pulling out. It locks by a grab-and-lock mechanism. The AC end can popped out and replaced. It pops out similar to how the battery cover on a remote control pops out, at the press of a plastic push-lever.
