tehoadapter
A tehoadapter, often referred to as a power adapter, is a device that provides electrical power to an electronic device by converting mains electricity to the voltage, current, and connector configuration required by the device. Adapters can be external, known as wall warts, or built into the device itself.
Most teho adapters fall into two broad categories: linear power supplies and switching-mode power supplies (SMPS).
Electrical characteristics include an input in the range of typical mains voltages (about 100–240 V AC, 50/60
Safety and standards: tehoadapter must provide galvanic isolation and protection against overvoltage, overcurrent, short circuits, and
Practical considerations include matching the device’s required voltage and current, using the correct connector and polarity,
