Power supply noise reducer accepts a voltage range of 12V to 55V and a current of 10A via DC 5.5/2.5mm jack. It reduces power supply noise and protects your equipment from electromagnetic interference, thanks to  filter capacitors and inductors. Another advantage of this power noise reducer is that it reduces the impact of power surges and spikes on devices, thus extending their life. A doubler DC 5.5/2.5mm jack is also supplied, enabling two devices to be powered simultaneously.
