Keithley PWS2323 DC Power Supply, 0-32 V, 3 Amp

positive and negative polarity DC voltage outputs are often needed to drive various electric circuits and components one common example is driving op amps like the one illustrated here in which a positive 10 volts and negative 10 volts is needed to drive the amplifier some DC power supplies may already have these polarity outputs available however many power supplies do not have them available you can still get positive and negative voltage outputs as long as you have at least two DC power supplies with floating outputs today I will show you how to set up to being a precision 1787 B DC power supplies to get a positive and negative voltage output I will also show you how to do the same on a B&K precision 1673 triple output power supply to get positive and negative voltage outputs from 1787 B supplies the setup is simple Connect both 1787 B in a series connection so connect the positive t
