Boost Voltage 60...250 Vdc 1 240Vdc The boost voltage (also referred to as the “250Vdc rail”) is the power source for
actuator operation. The boost voltage is adjustable via communications. This
voltage is connected to the drain side of the IBGT on the UPD board. This
voltage may change with the needs of each pole type driven by the UPD. The
value is a non-signed byte. Setting the Boost voltage to 60 will switch off the
function.
