DC-DC Converter for Railway Vehicles "RSDH Series"
Supports ultra-wide input from DC 250V to 1,500V. Provides stable power supply to control equipment in railway vehicles.
In the railway industry, vehicle power supply systems require high reliability to continuously provide stable power to control equipment even in high-voltage environments. Particularly, the durability of the power supply unit is a crucial factor directly linked to the stable operation of the vehicle during long-term use under voltage fluctuations and harsh conditions. The RSDH Series is an insulated DC-DC converter that supports an ultra-wide input range of DC250V to DC1,500V, achieving stable power supply in high-voltage DC environments. Additionally, its internal coating makes it resistant to dust and dirt, designed for long-term operation. 【Usage Scenarios】 - Power supply to control equipment within railway vehicles - Voltage reduction and stabilization from high-voltage DC power lines - Power supply systems within vehicles that require long-term operation 【Benefits of Implementation】 - Ultra-wide input range allows compatibility with various high-voltage environments - Improved environmental resistance through internal coating reduces maintenance burden - Compact 1U size effectively utilizes limited space within vehicles
