This document describes how to construct a dual polarity linear power supply which can be configured for any positive or negative voltage between 1 2 35v. 1 5v 3v 4 5v 6v 9v at 1 5a selector voltage regulator. 350 ma to 13 2 a.

Datasheets are readily available online and easily found. Dual voltage variable power supply. It converts the alternating current ac from our wall outlets into direct current dc at some. Dual supplies have three outputs for example a 9v supply has 9v 0v and 9v outputs.

Linear regulated power supplies only provide one output voltage. 1 5 vdc to 150 vdc output current. 33 48 of over 6 000 results for dual voltage power supply tekpower tp3003d 3 digital variable triple outputs linear type dc power supply 0 30 volts 0 3 amps 4 0 out of 5 stars 21. 1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups.

Linear technology s ltc3265 is a low noise dual polarity output power supply which includes a boost charge pump an inverting charge pump and two low noise positive and negative ldo post regulators the boost charge pump powers the positive ldo post regulator while the inverting charge pump powers the negative ldo regulator. Linear regulators can only be used to step down voltage. As a result power supplies are sometimes referred to as electric power converters some power supplies are separate standalone pieces of equipment while. Our next step toward a useful lab power supply is a dual polarity supply with both voltages variable.
