Polaroid CU-5 AC Power Pack
Accession Number: 2019.ast.164
This object is a power pack for a Polaroid camera. It consists of a rectangular box standing on four rubber feet, with one face a slightly slanted control panel, and at the rear places to plug in power and other cables to attach the camera and camera flash. On the control panel there are two large switches, one which reads ON and OFF and the other one which reads “TEST”. The “test” switch, if depresses, immediately resets. In the centre of the panel there is a dial that can rotated to move between “DARKEN” and “LIGHTEN”. Next to this dial, someone has drawn and arrow that indicates the lowest setting.
On the rear there are several plug connectors. One of these is connected with a knurled knob and is labelled, “CAMERA CORD”. Next to this there is a small female socket with one prong smaller than other other; this is labelled “FLASH”. Next to this is a recessed male power cable connector; there is also an associated power cable that fits this plug. Also on the back there is a cylindrical fuse insert, reading “FUSE”. This is labelled “1/2 AMP S-B FUSE”.
There are two folded leaflets that provide information about Polaroid film stored with the object.
