MORNSUN Expands Rail R3 DC/DC converters up to 40W in 2*1 package

MORNSUN recently launched a new Rail R3 DC/DC converters URF1D_LD-40WR3, as an extension of MORNSUN 6-20W rail R3 DC/DC converters.  

This new series URF1D_LD-40WR3 provides a wide input voltage range of 40-160VDC required by input voltages of 72V, 96V, 110V in the railway industry. Outputs and isolation voltage up to 3000VDC/1500VAC ensure them to meet the railway locomotive EN50155 standard requirements and EN62368 standard requirements. The converters also offer a wide operating temperature range of -40℃ to +85℃. Protections for input UVP, OSC, OCP, OVP, and OTP are also included. Housed in 2*1 inch DIP package, this URF1D_LD-40WR3 series is available for packages with an optional heat sink in PCB mount, chassis mount and DIN rail mount, which offers flexibility to the designer of the end-product and makes this series ideal for applications in railway monitoring, lighting equipment, information display, and other railway vehicle-related equipment.
