Obtain a power supply that has the correct output voltage that you need.
Yes. Depending on the design, the power supply can provide any voltage desired.
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.
Yes.
There is no transformer used in PC power supply. There is rectifier used to rectify or convert AC input voltage into DC output voltage.Transformer based rectifier produces some spikes at the output DC voltage, hencethey uses SMPS (Switch Mode Power Supply) to avoid spikes to the output DC voltage and get a smooth DC voltage.
by d way input only
Output is: DC10V - 800mA - Center Positive
Power supply providing constant D.C. output voltages from variable A.C. input voltagesThe novel power supply for generating a constant d.c. voltage from a variable a.c. voltage supply line, includes a plurality of switch circuits (10, 12) which monitor voltage levels on respective secondary windings (L,M,H) of a power transformer and as voltage levels change, one of the plurality of switch circuits is selected to charge a capacitor (C1) which provides a range of d.c. voltages which are processed to provide the constant d.c. voltage.
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.
