R3 DC/DC Converter for Rail Track Circuit Reader System Application
Generally, the power source is a near-100w DC-DC converter, which steps down the 110V to 24V then to 5V as power to the system board that consist of MCU, 485, CAN and some display units.
MORNSUN URB2412LD-20WR3 can power the DTU unit. Because the rail track reader system includes 2 packages of power supply solutions, and each of the systems shall be installed 2 packages of power converters independently, for which MORNSUN rail transportation specified DC-DC suitable.
