QUT1 power unit and transformer

The QUT1 power unit is designed to supply power for add-on units of up to
11 SL-1 telephones or attendant consoles from a centralized location.
When AC transformers are used to provide auxiliary power to attendant
consoles or sets, a separate 25 V and/or 15 V ac transformer is required for
each attendant console or telephone.
Figure 45 illustrates the QUT1 power unit faceplate, and Figure 46, the
QUT1 power unit connection.
Table 29 gives data on QUT1 power unit fusing, and Table 30 lists the QUT1
connections. Tables 31, 32, and 33 list the allowable distances from the
QUT1 to the telephone, the Lamp Field Array module, and the attendant
console, respectively.
