Speck Electronics SSM - Manual (Page 19)

Chapter 3 Installation Section
There are five terminals available on the power transformer of the power
supply. The configuration of the five terminals determines the operating
voltage of the power supply. It is only necessary to change the black
(line) and white (neutral) AC wires. Do not attempt to remove or
change the Green AC safety wire or the multicolored wires used at the
DC terminals. It is recommended that you measure the DC voltages at
the circular DC connector before reconnection to the mixer.
The following chart represents the proper AC terminal configuration for
the Model PS3-1.5 power supply.
The following chart represents the proper fuse rating for the
Model PS3-1.5 power supply. All fuses are 3AG Slow-Blow type.
