The Mean Well Control allows for two Mean Well switching power supplies to be connected in series and used to power an audio amplifier.
The Mean Well EPP-300, RPS-300, EPP-400, and RPS-400 models are excellent switching power supply choices for an LM3886-based power amplifier, such as my Modulus series. However, as these supplies have only one output, they must be configured properly for use as a dual or split supply. In addition, the Mean Well supplies feature low-voltage on/off control, thus, need a little bit of digital logic to interface to a regular power switch and 12 V trigger.
