The URB2412YMD-20WR3 is a high-performance, single-output 20W DC/DC Converter specifically designed for mission-critical applications in harsh environments, including railway, industrial control, and telecommunications. This robust module features an ultra-wide 4:1 input voltage range of 9VDC to 36VDC, ensuring stable and reliable operation across the significant voltage fluctuations typical of 24V battery and bus systems. It delivers a precisely regulated 12VDC output with a maximum current of 1667 milliamperes (1.667A).

Engineered for extreme reliability, the URB2412YMD-20WR3 boasts an exceptional operating ambient temperature range of -40 to +105 , making it suitable for deployment in the most challenging thermal conditions. Its high efficiency, up to 91%, minimizes power loss and heat generation, further enhancing its reliability. Safety and compliance are key, with an I/O isolation test voltage of 1500VDC and compliance with the stringent EN50155 railway standard. The converter includes comprehensive protection features: input under-voltage protection (UVP), and output short-circuit (SCP), over-current (OCP), and over-voltage protection (OVP). Furthermore, the chassis (A2S) or DIN-rail mounting (A4S) versions offer input reverse polarity protection, ensuring system integrity even during incorrect installation.
