standardspänningar

Standardspänningar, or standard voltages, refer to the nominal or commonly used voltage levels in electrical systems and for powering electronic devices. These voltages are standardized to ensure compatibility and interoperability between different electrical components and appliances. For instance, household electrical outlets operate at specific standard voltages, which vary by region. In many parts of Europe, the standard mains voltage is 230 volts, while in North America, it is typically 120 volts.

The use of standard voltages simplifies the design and manufacturing of electrical equipment, as manufacturers can produce devices intended to operate reliably within these defined parameters. It also benefits consumers, allowing them to purchase appliances and electronics that will function correctly when plugged into the standard electrical outlets in their homes. Beyond mains power, standard voltages are also crucial for low-voltage DC power supplies, such as those used for charging mobile phones or powering small electronic gadgets. Common DC standard voltages include 5 volts, 9 volts, and 12 volts. Adherence to these standards minimizes the risk of damage to devices due to overvoltage or undervoltage conditions and ensures efficient energy transfer.
