This LOF550-20B12 switching-mode power supply module delivers 12V and 41A for 550W of power. The module features high-quality components and is mounted on a metal plate for efficient heat dissipation. The LOF550-20B12 power supply accepts a wide input voltage range from 90V to 260V AC. Moreover, the module incorporates PFC (Power Factor Correction), enabling it to achieve an efficiency rate of 91%. If required, you can adjust the output voltage from 11.4V to 12.6V using an adjustable resistor.

In addition to its AC input connectors and positive and negative output screw terminals, the LOF550-20B12 is equipped with a 2-pin connector for powering a fan for optimum heat dissipation. A 4-pin input for end-of-line voltage compensation (feedback compensation) and its offset are also present. This enables the power supply's output voltage to be self-regulated according to the needs of the powered module, should the voltage delivered suffer losses in the conductors due to the distance between the power supply module and the powered module.

Finally, all necessary protections, such as overtemperature, overcurrent and overvoltage protection, are built into the module. The LOF550-20B12 power supply is an ideal choice for any DIY audiophile project requiring a powerful, high-quality power supply.
