4. POWER STAGE
The DC voltages required at various parts of the chassis and inverters are provided by a
main power supply unit. The power supply generates 33V, 24V, 12V, 5V, 3,3V and 5V,
3,3V stand by mode DC voltages. Power stage which is on-chasis generates 1,26V
stand by voltage and 8V, 2,6V, 1,8V and 1V supplies for other different parts of the
chassis.
