The LM25-23B12 is a compact, 25W AC-DC Switch Mode Power Supply (SMPS) housed in a small outline metal case. This power supply is designed to provide a highly reliable, cost-effective, and energy-efficient solution for systems requiring a stable 12V power source, particularly in industrial, LED, security, and smart home applications.
A key feature is its universal and ultra-wide input voltage range of 85 ~ 305VAC and 100 ~ 430VDC. This broad input capability allows the module to be used globally and provides high resilience to fluctuations in the input power source. The SMPS delivers a single, regulated output of 12VDC with a current capacity of 2.1 Amperes, making it suitable for powering various control circuits and devices.
The LM25-23B12 is built for reliability, featuring a high I/O isolation test voltage of 4000VAC for enhanced safety and noise immunity. It boasts high efficiency, up to 88%, and extremely low no-load power consumption (< 0.5W), contributing to energy savings and reduced heat generation. The unit is designed to operate across a wide ambient temperature range of -30 to +70 . The metal case aids in heat dissipation, contributing to a long operational life. Comprehensive protection features, including output short circuit, over-current, and over-voltage protection, ensure the safety of the power supply and the connected equipment.
