DC Power Supply

General description of used DC Power Supply 's for sale.
A DC power supply usually uses a transformer to convert the voltage from the wall outlet to a different, usually lower, voltage. A rectifier is used to convert alternating voltage to a pulsating direct voltage, followed by a filter, comprising one or more capacitors, resistors, and sometimes inductors, to filter out (smooth) most of the pulsation. A small remaining unwanted alternating voltage component at mains or twice mains power frequency (depending upon whether half- or full-wave rectification is used)—ripple—is unavoidably superimposed on the direct output voltage. For purposes such as charging batteries the ripple is not a problem, and the simplest unregulated mains-powered DC power supply circuit consists of a transformer driving a single diode in series with a resistor.

A linear regulated power supply may be used to set the voltage to a precise value, stabilized against fluctuations in input voltage and load. They are commonly used for laboratory and service shop test equipment.

Programmable power supplies allow for remote control of the output voltage through an analog input signal or a computer interface such as RS232 or GPIB.

Before the introduction of solid-state electronics power supplies used vacuum tubes. The tubes required high voltages; power supplies used step-up transformers, rectifiers, and filters to generate one or more direct voltages of some hundreds of volts, and a low alternating voltage for filaments.
