Product Details The 2000W LLC AC DC power supply module is a high-power switching power solution developed for digital audio amplifiers and other equipment requiring high-voltage DC rails. Using an LLC resonant switching architecture, the module converts 200–240V AC input into high-power dual DC outputs suitable for amplifier power stages.Unlike a conventional low-power AC DC adapter, this board is designed to serve as the main power conversion stage inside high-power electronic equipment. Its output architecture is particularly suited to audio amplifier designs that require positive and negative DC rails for the power amplification circuit, while additional auxiliary outputs can support control or driver circuitry.The module supports multiple main output configurations, including ±50V, ±55V, ±60V, ±65V, ±70V, ±75V, ±80V, ±85V and ±90V options. This range allows the power supply to be matched with different amplifier architectures and output-power requirements rather than limiting the design to a single fixed DC voltage.For the ±80V configuration, the main output is specified at up to 11A, with additional auxiliary and independent 12V outputs available for supporting circuits. These auxiliary rails can be used where an amplifier design needs separate low-voltage power for control, protection, signal-processing or related electronic sections.The LLC topology is particularly relevant to high-power audio equipment because resonant switching operation can provide efficient energy conversion while reducing switching losses under suitable operating conditions. The module is specified with high conversion efficiency, helping reduce wasted power and the associated thermal load when properly installed and cooled.Its approximately 207 × 100 × 45 mm format makes the module suitable for integration into amplifier chassis and other equipment where the AC-DC conversion stage needs to be installed as part of the overall product rather than used as an external adapter.The power supply can be used in digital power amplifiers, high-power Class D amplifier systems, professional audio equipment and customized Hi-Fi products. Its multiple output configurations also make it useful for amplifier developers who need to select a DC rail according to the voltage requirements of a particular amplifier design.Thermal management becomes increasingly important when operating a high-power supply continuously. The specified continuous, rated and instantaneous power levels are different, and long-duration operation at elevated power may require forced-air cooling. System designers should therefore consider airflow, enclosure temperature, load profile and available cooling space when integrating the module.Because this is a board-level high-voltage AC-DC power supply, installation requires appropriate electrical isolation, enclosure protection, grounding and wiring practices. The AC input section should not be treated like a low-voltage DC module, and the complete assembly should be designed to prevent accidental contact with hazardous voltages.The 2000W LLC power supply module is therefore best suited to amplifier manufacturers, audio equipment developers and engineers building high-power audio systems that require an integrated AC-to-dual-DC conversion stage. Its selectable high-voltage rails and auxiliary outputs provide greater flexibility than a fixed-voltage external power adapter when designing a dedicated amplifier platform.
