Converter 150W 14.4~33.6V-24V 6.3A RSD-150B-24

Professional DC/DC Converter for Railway Industry

The RSD-150B-24 converter is an advanced power supply solution specifically designed for demanding applications in the railway industry and rail transport. The device provides a stable output voltage of 24V DC at a current of 6,3A and power of 150W, making it ideal for powering control systems, lighting, and auxiliary devices in railway carriages.

Power Supply Construction and Safety

The RSD series features a wide input voltage range of 2:1 (16,8~31,2V DC), ensuring flexibility with various power sources encountered in rail vehicles. Galvanic isolation between input and output at 4000VDC guarantees system safety and eliminates ground loop issues.

The advanced protection system includes:

• Overload Protection (OPP) - constant current limiting to prevent damage
• Overvoltage Protection (OVP) - automatic shutdown upon exceeding allowable voltage
• Thermal Protection (OTP) - automatic shutdown in case of transformer overheating
• Input Reverse Polarity Protection - MOSFET in the negative circuit protects against installation errors

Operating Parameters and Environmental Conditions

The device operates in an extreme temperature range from -40°C to +70°C, maintaining full functionality without derating up to +55°C. Above this temperature, gradual load reduction is required according to the derating curve.

Energy efficiency of approximately 90% at full load minimizes thermal losses and reduces cooling requirements. The "half-potted" construction ensures optimal heat dissipation and protection against moisture.

The built-in LED status indicator enables quick device diagnostics - green light indicates normal operation, while no signal indicates lack of power or failure.

Regulatory Compliance and Certifications

The converter meets the rigorous requirements of railway standards:

• EN50155 - standard for electronic equipment in rail vehicles
• EN45545-2 - fire protection requirements for materials
• EN50121-3-2 - electromagnetic compatibility in rail transport
• IEC60571, IEC61373 - vibration and shock resistance tests

Additionally, the device holds IEC/UL62368-1 safety certifications and meets EMC requirements according to EN55032 Class A/B, making it compatible with international electrical installation standards.

105°C long-life electrolytic capacitors and a three-year manufacturer warranty from MEAN WELL ensure long-term, reliable operation in the harsh environmental conditions characteristic of rail transport.
