signal for the default configuration of the power module. (Refer to Sheet 1
of the schematics). This signal is provided for the support of active power
factor applications where the incoming power source is AC and a voltage
boost circuit is used to control the incoming current. The power module
PCB supports the components for an active power factor correction circuit.
These components are not installed on the low voltage version of the power
module.
