Product Description
MEAN WELL RSD-200D-48 is a 200W railway certified regulated isolated DC/DC converter offering a reliable 48V DC output from a DC input range of 67.2V to 110V, designed primarily for use in vehicles equipped with DC power sources. With a chassis mount form factor measuring 191mm in length, 40mm in width, and 40mm in depth, this converter provides a compact low-profile solution certified to withstand industrial and railway environments.
The device features an operational temperature range from -40°C to 70°C, allowing it to perform efficiently under harsh ambient conditions. It achieves high efficiency up to 91%, improving overall system energy use. Advanced built-in protection circuits guard against short circuit, overload, over voltage, and over temperature situations, ensuring long-term reliability.
This DC/DC Converter complies with relevant railway standards including EN50155, IEC60571, IEC61373, and EN50121-3-2 for shock, vibration, and electromagnetic interference, making it suitable for transportation and industrial automation applications.
The semi-encapsulated design safeguards the PCB from mechanical damage and environmental hazards. It also incorporates 5G anti-vibration resistance and includes LED indication for power status, contributing to ease of maintenance.
The single output of 48V DC delivers a maximum output current of 4.2A with low ripple noise of 180mV peak-to-peak, and an isolation voltage of 4kV DC provides safe separation between input and output circuits.
Typical use cases include railway signalling, industrial automation, transportation power supplies, and other heavy-duty applications requiring robust DC/DC power conversion. The converter has a mean time between failures (MTBF) of 218,200 hours per MIL-HDBK-217F standards at 25°C, supporting long operational life.
Invest in the MEAN WELL RSD-200D-48 for reliable, efficient, and certified DC/DC power conversion in challenging environments.
