Technical FAQs 4

How do you Connect DC power supplies in series?

Connecting DC power supplies in series involves linking the positive terminal of the first power supply to the negative terminal of the second power supply. This setup combines the output voltages of both supplies while keeping the current constant throughout the circuit.

When do you need a series connection of power supplies?

In critical applications that need power supply redundancy, redundant connected power supplies can be used. Series connection of power supplies may be used when higher output voltage is desired than that can be obtained from one power supply.

Why are power supplies connected in series?

Conversely, connecting power supplies in series ensures that each supply provides the necessary load current, resulting in the load receiving a combined output voltage from the series-connected supplies.

Can a power supply be used in a series output configuration?

However, there are certain limitations imposed on power supplies when used in a series output configuration. One such limitation is that the supplies’ outputs must be designed to withstand the voltage offset caused by the series connection.
