6    Component DC Power Supply Specification
Below the Calculated Output Values area is where DC power supply values are entered (see Figure 11). Provision is made for up to four supply voltages. Efficiency values are used to calculate what the power supply input power requirements will be. Enter values only in the cells with colored backgrounds. A total input power value is also calculated.
