LMF75-20B12: 75.6W Metal Case PS, 12VDC @ 6.3A, Active PFC, 300VAC Surge

The LMF75-20B12 is a high-reliability, 75.6W AC-DC Switch Mode Power Supply (SMPS), housed in a robust metal case. This power supply is a premium solution for industrial and commercial applications, featuring Built-in Active Power Factor Correction (PFC) to ensure high efficiency and compliance with harmonic current regulations. It is engineered to provide a highly stable, efficient, and reliable 12V power source with a high current capacity.

A critical feature is its universal input voltage range of 85 ~ 264VAC and 120 ~ 370VDC, which allows for global use and provides excellent tolerance to input voltage fluctuations. Notably, it can withstand a 300VAC surge input for 5 seconds, enhancing its robustness in unstable power environments. The unit delivers a single, regulated output of 12VDC with a substantial current capacity of 6.3 Amperes, offering powerful and consistent energy to connected loads.

The LMF75-20B12 is built for endurance and advanced control. It operates reliably across a wide ambient temperature range of -25 to +70 . It features a high I/O isolation test voltage of 4000VAC for enhanced safety and is compliant with CISPR32/EN55032 CLASS B for emissions without the need for extra external components. The inclusion of a Remote ON-OFF control function provides system-level power management flexibility. Integrated protection circuits, including output short circuit (with built-in constant current limiting), over-current, over-voltage, and over-temperature protection, safeguard both the power supply and the critical equipment it powers. The unit is safety approved to standards including IEC/EN/UL62368, EN60335, EN61558, and GB4943.
