MEAN WELL DDR-15L-12
Compact industrial DC-DC converter designed for DIN rail mounting with ultra-wide input range and extreme temperature resistance.
Model DDR-15L-12 is a professional DC-DC converter with an output power of 15 W. The device offers an ultra-wide input range of 18–75 V DC with a 4:1 ratio, ensuring stable operation even with significant input voltage fluctuations. The output voltage of 12 V DC is adjustable in the range of 9–13.2 V and provides current up to 1.25 A.
The converter is designed for the most demanding industrial applications with an operating temperature range of -40 to +85 °C. The width of only 17.5 mm allows space-saving mounting on standard DIN rail TS-35/7.5 or TS-35/15. High efficiency of 86% and free convection cooling ensure reliable and quiet operation without the need for a fan.
- Ultra-wide input range of 18–75 V DC with 4:1 ratio for stable operation during voltage fluctuations
- Compact design with width of only 17.5 mm for space-saving DIN rail mounting
- Extreme temperature resistance from -40 to +85 °C for demanding industrial environments
- Adjustable output voltage in the range of 9–13.2 V with tolerance of ±2%
- Comprehensive protection against overload, overvoltage, undervoltage and reverse polarity
- Galvanic isolation of 4 kVDC between input and output for high safety
- Low output voltage ripple of maximum 60 mVp-p at full load
- Certifications UL 62368-1, IEC 62368-1, AS/NZS 62368-1 for international use
Advanced protection features
The converter features a complete set of protections including overload protection with hiccup mode (automatic recovery after fault removal), overvoltage protection with output shutdown, undervoltage protection with threshold of 18 V, and reverse polarity protection using internal MOSFET transistor without damaging the device.
High reliability and EMC
The device complies with strict electromagnetic compatibility standards BS EN/EN55032 class B for emissions and BS EN/EN61000-6-2 for immunity to interference. Mean time between failures MTBF reaches 907,000 hours according to MIL-HDBK-217F at 25 °C, guaranteeing long-term trouble-free service life.
Easy installation and use
The converter is equipped with a 4-pin terminal block connector for easy connection of input and output voltage. LED indicator signals proper device operation. The unit complies with vibration tests according to IEC60068-2-6 (10-500 Hz, 2G) and is suitable for operation at altitudes up to 2000 m.
