Bell System PS4A power supply unit, Wall Mount

Who this is for

For the installer — this is the power supply unit supplied under Bell System part number PS4A. Specify it by that part number.

In plain English: this is a power supply unit made by Bell System. The part number PS4A is the manufacturer's own code for this exact version of it.

Similar-looking items in the same family often differ only by a suffix on that code. If you are replacing something, match the code rather than the picture.
