MEAN WELL Isolated DIN Rail DC/DC Converter, 24V 10A 240W

The MEAN WELL DDR-240C-24 is a robust 240W isolated DC/DC converter designed for secure and efficient DIN rail mounting. Engineered with a focus on reliability and safety, it features a 4kVdc I/O isolation barrier, enhancing protection and system integrity in demanding environments. Its ultra-slim 40mm width allows for space-saving installation in crowded electrical cabinets, making it an ideal choice for modern industrial control systems.

This converter offers a 2:1 wide input voltage range from 33.6 to 67.2 VDC, providing flexibility and resilience against input voltage fluctuations. The output is rated at 24V DC, 10A, delivering a stable 240W of power with a typical efficiency of 91%. For higher power needs, the unit supports current sharing, allowing up to three units to be paralleled for a combined output of up to 960W. Output voltage is also adjustable for precise application requirements.

Comprehensive protection is built-in, including safeguards against short circuit, overvoltage, overload, input reverse polarity, and input under-voltage. It is cooled by free air convection and features a remote ON/OFF control for convenient system integration. Designed to operate reliably in a wide temperature range from -40°C to +70°C, it is built for harsh conditions.

Key Applications & Compliance

This DC/DC converter is certified for critical transport and industrial applications. It meets BS EN/EN45545-2 for fire protection, BS EN/EN50155/IEC60571 including IEC61373 for shock and vibration resistance in railway environments, and BS EN/EN50121-3-2 for electromagnetic compatibility (EMC). This makes it perfectly suited for use in buses, trams, metro systems, railway control, security systems, factory automation, and telecommunications infrastructure. It is also ideal for voltage drop compensation along long cables and for increasing the insulation level of a DC system.
