EN50155 Compliance Dual Output DC/DC Converters for Railway- URA1D-(X)LMD-10WR3 SeriesFeb 25, 2019      view:
MORNSUN launched its new dual output DC/DC converters URA1D-(X)LMD-10WR3 for railway applications, as an extension of MORNSUN 10W single output railway R3 DC/DC converters.

This new series URA1D-(X)LMD-10WR3 not only offers positive and negative outputs but also provides a wide input voltage range of 40-160VDC required by input voltages of 72V, 96V, 110V in vehicle battery power supply system. 2250VDC reinforced I/O isolation voltage ensures them to meet the railway EN50155 standard requirements, UL62368, IEC62368 and EN62368 standard requirements. Protections for input UVP, OSC, OCP, and OVP are also included. Housed in 2*1 inch DIP package, this URA1D-(X)LMD-10WR3 series is available for packages with 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 industry. 

Widely used in applications of dc power distribution system, railway monitoring, lighting equipment, air condition controller, information display and other railway vehicle-related equipment.
