The SL Power Electronics LB240S56K is a high-density, single-output open-frame AC/DC power supply designed for industrial and dimming applications. It provides a total power of 240 Watts and operates with a universal input voltage range of 90 to 264 VAC.
Key electrical specifications include a 56V output voltage and 4.29A output current, resulting in 240W of power. The converter boasts high efficiency, typically 92% to 94%, and features Power Factor Correction (PFC) and universal input capabilities. It is designed to deliver full rated output power up to 50°C ambient with 300 LFM airflow.
This power supply meets stringent safety standards, including EN/CSA/IEC/UL 62368-1, and complies with EMI standards such as EN55015 Class B conducted emissions. Its compact dimensions of 5.00" L x 3.00" W x 1.22" H (127.0mm x 76.2mm x 31.1mm) make it suitable for space-constrained designs. The operating temperature range is -10°C to 70°C.
Applications for the LB240S56K include ITE (Commercial) and dimming applications where power density and cost-effectiveness are critical. It offers protection features such as overvoltage, short circuit, and thermal protection.
