MORNSUN expands it’s product range for DC/DC railway converter 

MORNSUN recently launched a new R3 DC/DC converters for railway applications. The URF1D_LD-40WR3 is 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.

Features :

  • Ultra-wide input voltage range: 40-160VDC
  • Enhanced isolation, isolation voltage: 3000VDC/1500VAC
  • Operating temperature range: -40°C to +85°C
  • Input Under-voltage protection, output short circuit, over-current, over–voltage protection, over-temperature protection
  • Internationale standard pin-out
  • Reverse voltage protection available with A2S(Chassis mounting) or A4S(35mm DIN-Rail mounting)
  • Meets the requirements of railway standard EN50155
