The common terms used in power adapters are:
- Output Voltage: the voltage that the adapter outputs to power the device.
- Output Current: the amount of current that the adapter outputs to power the device.
- Input Voltage: the voltage that the adapter requires from the power source to operate.
- Input Current: the amount of current that the adapter requires from the power source to operate.
- Power Rating: the maximum amount of power that the adapter can supply to the device.
- Efficiency: the ratio of output power to input power, expressed as a percentage.
- Ripple Voltage: the small fluctuations in the output voltage caused by the switching of the power supply.
- Load Regulation: the ability of the adapter to maintain a constant output voltage when the load on the device changes.
- Line Regulation: the ability of the adapter to maintain a constant output voltage when the input voltage from the power source changes.
- Overload Protection: a safety feature that shuts down the adapter if the output current exceeds a certain level.
- Short Circuit Protection: a safety feature that shuts down the adapter if a short circuit occurs in the device being powered.
- Overvoltage Protection: a safety feature that shuts down the adapter if the output voltage exceeds a certain level.
- Undervoltage Protection: a safety feature that shuts down the adapter if the input voltage falls below a certain level.
- Temperature Protection: a safety feature that shuts down the adapter if the internal temperature of the adapter exceeds a certain level.
