Product Description
MEAN WELL RSD-150D-12 is a 150W railway certified regulated isolated DC/DC converter with a single 12V DC output and a wide input voltage range of 67.2V to 143V DC. This chassis mount converter offers a low profile height of 36mm ensuring integration versatility in space-constrained applications.
Designed specifically for railway and vehicular systems, it meets stringent standards including EN50155, IEC60571, IEC61373 for shock and vibration, as well as EN50121-3-2 for EMC compliance. The converter is semi-encapsulated for robust PCB protection and provides high efficiency up to 92%, minimizing energy loss and heat generation.
Protection features include short circuit, overload, over voltage, over temperature, and reversed input polarity safeguarding system reliability. Its 4kV DC isolation voltage enables safe operation in electrically noisy environments. The unit also employs a constant current limiting circuit and uses 105°C long-life electrolytic capacitors to enhance durability.
The operating temperature range from -40°C to 55°C makes it suitable for harsh industrial and railway environments. It is cooled by free air convection and has a MTBF of 223,200 hours ensuring long-term reliability.
Additional benefits include LED power-on indication and 5G anti-vibration capability, providing diagnostic insights and resilience to mechanical shocks. The compact dimensions of 189mm length, 77mm width, and 36mm depth facilitate easy chassis mounting in electrical enclosures.
The converter supports a 2:1 wide input voltage ratio enabling flexible power sourcing. Complies with IEC60950-1 safety standards and railway certifications. Suitable for industrial, railway, transportation, and other commercial DC power applications.
Each unit undergoes 100% full load burn-in testing to ensure quality and performance. It is semi-encapsulated to protect PCB circuitry from environmental and mechanical stresses.
MEAN WELL products are widely recognized in electronics and electrical applications for robustness and reliability. This RSD-150D-12 DC/DC Converter is ideal for applications requiring regulated isolated DC voltage conversion meeting railway industry certifications.
