This power supply module enables a second module requiring 12V DC input voltage to be powered from 110V-230V AC. It's perfect, for example, for powering an amplifier stand-by module. It incorporates an HI-LINK HLK-PM12 AC/DC converter and a ZJY-2P01 filter to reduce noise and distortion in the electrical signal, keeping it clean. The output current of this module is precisely 12V and 250mA for a power of 3W.
