The LM75-23B05 is a high-power, 70W AC-DC Switch Mode Power Supply (SMPS), part of the LM75-23Bxx series, housed in a small outline metal case. This power supply is engineered to provide a highly stable, efficient, and robust 5V power solution with a high current capacity, making it an essential component for demanding industrial control systems, large LED displays, telecommunications equipment, and other applications requiring significant 5V power.
A defining characteristic is its universal and ultra-wide input voltage range of 85 ~ 305VAC and 120 ~ 430VDC. This extensive input capability ensures true global compatibility and provides exceptional tolerance to input voltage fluctuations, guaranteeing reliable operation even in unstable power environments. The unit delivers a single, regulated output of 5VDC with a substantial current capacity of 14 Amperes, offering powerful and consistent energy to connected loads.
The LM75-23B05 is built for reliability and safety in harsh conditions. It operates effectively across a wide ambient temperature range of -30 to +70 . It features low standby power consumption and high efficiency, which minimizes energy waste and heat generation. Safety is ensured by a high I/O isolation test voltage of 4000VAC and compliance with major international safety and EMC standards, including IEC/EN62368, EN60335, EN61558, and GB4943. The power supply utilizes terminal block termination for secure and straightforward installation. Integrated protection circuits, including output short circuit, over-current, and over-voltage protection, safeguard both the power supply and the critical equipment it powers.
