Product Description
The MEAN WELL DDR-15L-12 is an ultra slim, industrial-grade DC-DC converter engineered for DIN rail mounting. Featuring a wide 18 - 75V DC input range and a regulated 12V DC output at 1.25A, it offers flexible integration into control panels and automation systems whether the application is factory automation, process control, wireless communication, or industrial networking.
This converter boasts a compact profile with a width of only 17.5mm, making it highly suitable for space-constrained enclosures and electrical cabinets. The device ensures high operational efficiency up to 87%, minimizing energy consumption and heat generation. Its output voltage can be adjusted ±10% to support various loads and system requirements.
Designed to operate reliably across a wide ambient temperature window from -40°C up to 85°C, the DDR-15L-12 adapts to demanding industrial environments and ensures stable performance over extended periods. Reinforced 4kVDC I/O isolation enhances user and equipment protection.
No minimum load is required on the DC output, ensuring dependable power delivery regardless of load size. Cooling is achieved via free air convection, eliminating the need for external fans or active thermal management. The unit is compatible with standard DIN rail TS-35/7.5 or 15 mounting options.
Protection features include input reverse polarity, input under voltage safeguards, and a ripple/noise maximum of 100mV Pk-Pk for clean output. Compliance with major safety and electromagnetic compatibility standards - including IEC 62368-1 and UL508 - guarantees safe operation and global acceptance. The converter carries a 3-year warranty as standard.
Typical applications for this DC-DC converter encompass industrial control systems, factory automation installations, electromechanical interfaces, wireless network backbones, and telecom/datacom power distribution. Its robust build and certified performance meet the needs of electrical, electronics, and automation engineers seeking reliable, efficient, and certified DC conversion solutions.
