[GreenKeys] Teletype model 45 rectifier

[Duncan Brown]

Joe,

Yes, it is a loop supply. I'm not familiar with a "Model 45", but 
Teletype Corp used a lot of special connectors so that the user wouldn't 
get confused on where to plug them in.  If you don't have the specific 
Teletype Corp. table that went with that supply, the special plugs are 
meaningless.  The cord with the male contacts will be the 120VAC input, 
the cord with the female contacts will be the 120VDC loop supply. (Ohm 
them out to be sure!) Cut off the special connectors and wire it into 
your system.

You will need about 2000 Ohms in series to limit the current to 60 ma.

have fun,

Duncan
