Mornsun URE1D_LD-20WR3 series DC/DC converters with EN50155 rail compliance

Mornsun’s 20 W range of DC/DC converters, the URE1D_LD-20WR3 series, has been added due to market demand for dual-output devices (positive and negative). The converters provide a wide input voltage range of 40–160 VDC due to input voltages of 72, 96 and 110 V used in the railway industry.

The 50 x 25 mm international standard package is available in PCB mount, chassis and DIN-rail mounting with heatsink options, making the series suitable for use in DC distribution systems, railway monitoring, lighting equipment, air-conditioning controllers, information display and other railway vehicle-related equipment.

The devices feature enhanced isolation voltage of 3000 VDC and a wide operating temperature of -40 to 85°C. Protections include input undervoltage, output short circuit, overcurrent and overvoltage, with low ripple and noise. Positive and negative outputs and 3 kVDC isolation voltage ensure the converters meet railway EN50155 standard requirements. Reverse voltage protection is available with A2S (chassis mounting) or A4S (35 mm DIN-rail mounting) packages.
