ACväljundeid

ACväljundeid is the Estonian term for outputs that supply alternating current to a load. The phrase is used in electrical engineering and consumer electronics to refer to any point where AC power exits a source, such as a wall outlet, an inverter, a power supply, or a generator. The closest English equivalents are AC outputs or alternating-current outputs.

AC outputs are defined by several electrical characteristics, notably nominal voltage, frequency, and waveform. In Europe the standard is typically 230 volts at 50 hertz with a sinusoidal waveform, while in North America 120 volts at 60 hertz is common. The output can be a fixed receptacle or a connector on a device. Waveforms range from pure sine waves to modified sine or square approximations, depending on the source and the intended load. Protective features such as isolation, grounding, and overcurrent protection are common.

AC outputs appear in many contexts, including building electrical outlets that power household appliances, portable inverters and uninterruptible power supplies (UPS) that provide AC during outages, solar and other power converters, and laboratory equipment such as signal generators or power amplifiers. The term emphasizes delivering AC power rather than DC.

Safety considerations for ACoutputs include proper grounding, adherence to voltage and frequency ratings, correct connector types, and compliance with local standards. Misuse or mixing AC outputs with DC circuits can be hazardous and is generally prohibited.
