How do I connect two DC power supplies in series?
To connect two DC power supplies in series, connect the positive terminal of the first power supply to the negative terminal of the second power supply to form a "daisy-chain" connection, where the series voltage is the sum of the voltages of the two power supplies. To connect two DC power supplies in series, proceed as follows: Note that the voltage of the load should be equal to or higher than the sum of the voltages of the two power supplies to prevent damage to the load or power supply. In addition, the load's rated...
