MORNSUN LOF225-20B19
SMPS Switching Mode Power Supply 225W 19V 11A PFC
This LOF225-20B19 SMPS switching power supply module delivers 19V and 11A for a total power of 225W. The LOF225-20B19 accepts a wide supply voltage range from 90V to 260V AC or 120V to 370V DC via a 2-pin JST B2P-VH connector. It features high-quality components and PFC (Power Factor Correction), enabling it to achieve 93% efficiency. If required, a variable resistor can be used to adjust the output voltage from 18.8V to 20V.
Connectors include a 6-pin JST B6P-VH and a 2.5mm 2A JST B2B-PH connector for powering an external fan for optimum heat dissipation.
Finally, all necessary protections, such as overtemperature, overcurrent and overvoltage protection, are built into the module. The LOF225-20B19 power supply is an ideal choice for any DIY audiophile project requiring a powerful, high-quality power supply.
Integrated PFC module
The LOF225-20B19 switching power supply features an active PFC (Power Factor Correction) with Mosfet transistor. The PFC enables a pre-splitting step to obtain a continuous, non-out-of-phase current at the power supply input. This has two advantages: firstly, the power supply's efficiency becomes optimum, with a rate of over 90%, and secondly, the advertised power values will remain as they are, whatever the input voltage to the PFC. For example, this power supply will deliver 225W whether the input voltage is 110V or 220V.
