DC-DC Converter for Railway Vehicles "DDR Series"
A vehicle power stabilization solution that balances reliability in accordance with railway standards and the convenience of DIN rail mounting.
In the railway industry, high reliability and power stabilization that can withstand harsh environments are required to ensure the stable operation of electronic devices within vehicles. Particularly in environments with severe vibrations, temperature changes, and voltage fluctuations during operation, insulation design and compliance with standards are essential. Inadequate power supply can lead to malfunctions or failures of equipment. The DDR Series supports power stabilization within vehicles through designs compliant with railway standards and a wide input voltage range. 【Usage Scenarios】 - Power supply for control systems within railway vehicles - Power supply for communication equipment and security control - DIN rail-mounted power supply for limited spaces 【Benefits of Implementation】 - High reliability due to compliance with BS EN/EN50155 and EN45545-2 - Environmental resistance with a wide operating temperature range of -40°C to +85°C - Space-saving achieved through a slim design (52.5mm)
