The LM25-23B03 is a compact, 20W 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 3.3V power source, particularly in space-constrained 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 3.3VDC with a substantial current capacity of 6 Amperes, making it suitable for powering microcontrollers, digital logic, and other low-voltage circuitry.
The LM25-23B03 is built for reliability, featuring a high I/O isolation test voltage of 4000VAC (implied by the series name) for enhanced safety and noise immunity. The unit features terminal block termination for secure and easy wiring. Its metal case aids in heat dissipation, contributing to a long operational life. The switch mode technology ensures high efficiency, minimizing power loss and heat generation. Comprehensive protection features (implied by the series name, typically including short circuit, over-current, and over-voltage protection) ensure the safety of the power supply and the connected equipment.
