COMBINATION CLASS "A" AND CLASS "B" HOOKUP
The PS-12/24-8 POWERPATH can be configured to have one Class "A" (2 Amps) and two Class "B" (2 Amps each circuit)
Outputs at the same time. This is done by opening or closing switches SW1 and SW2 on the logic board. NOTE: When SW1 is
"Closed", OUTPUTS 1 and 3 are the Class "A" circuit. When SW2 is "Closed", OUTPUTS 2 and 4 are the Class "A" circuit.
COMBINATION OF MODES
•
In Class "B" configuration, each output can be set to an independent mode as desired.
•
In Class "B", IN1 or IN2 can be selected to activate any of the outputs desired.
•
In Class "A", OUTPUT DIP Switches must be set identically for each Class "A" output.
