Piano Keyboard Charger
Piano power adapter for Piano Keyboard Router Speaker usage.Due to different models, functions and amplifiers, the electric energy used by the electronic organ is also large or small, ranging from 4.5V, 6V to 9V, 12V and 15V.
Description
Description
Digital piano headphone adapter,the quality 9V 2A paino power adapter for Paino applications. It will connect power to the paino keyboard power.The function of switching power supply is to convert a standard voltage into the current or voltage required by the user through different forms of architecture.
The switching transistor used by the switching power supply switches between the fully open mode (saturation zone) and the fully closed mode (cut-off zone). Both modes have the characteristics of low dissipation. The conversion between switching will have high dissipation, but the time is very short. Therefore, it saves energy and produces less waste heat. Switching power supply itself will not consume electric energy.The high conversion efficiency of switching power supply is one of its advantages. Moreover, because the switching power supply has high working frequency, small-size and light-weight transformers can be used. Therefore, the switching power supply will be smaller and lighter than the linear power supply.
