The LD20-23B12R2 is a high-performance 20W encapsulated AC/DC switch mode power supply module engineered for reliable operation in demanding industrial and commercial electronic systems. Designed with an ultra-wide input voltage range of 85-305VAC (100-430VDC), this compact module ensures stable and regulated 12VDC output under varying and unstable mains conditions.
Delivering 12VDC at up to 1.67A, the LD20-23B12R2 is well-suited for powering sensors, control circuits, instrumentation, automation devices, relays, communication equipment, and other 12V-powered electronics. Its high efficiency of up to 87% and extremely low no-load power consumption help minimize heat generation and overall system energy usage.
Encapsulated in a UL94V-0 flame-retardant plastic case, the module offers enhanced electrical isolation, environmental protection, and safety compliance. It meets strict EMC standards, including CISPR32/EN55032 Class B and EN55014, ensuring low electromagnetic interference in sensitive or mixed-signal systems.
With a compact PCB-mount form factor, wide operating temperature range, and suitability for high-altitude applications, the LD20-23B12R2 provides a robust, long-life solution for embedded power designs.
