Information on MEAN WELL DDR-15G-12
The MEAN WELL DDR-15G-12 is an ultra-compact 15 W DIN-rail DC/DC converter designed for effortless mounting on standard TS-35/7.5 or TS-35/15 rails, featuring an ultra-slim casing width of just 17.5 mm (1SU) to save critical space in control cabinets. Engineered with a wide 4:1 input voltage range of 9 to 36 V DC, it provides a stable regulated 12 V DC output at up to 1.25 A current. An onboard potentiometer allows users to adjust the output voltage between 9.0 V and 13.2 V to compensate for voltage drops across longer wiring distances, all while requiring no minimum load for stable operation.
Featuring a high efficiency rating of up to 85%, this converter relies entirely on fanless free air convection to operate smoothly over an extended operating temperature range of -40 °C to +85 °C. Strong electrical isolation is ensured by its 4 kV DC reinforced I/O isolation, protecting sensitive load devices from system noise and transient surges. Complete protection features are built-in, including defenses against short circuit, overload, overvoltage, input reverse polarity, and input undervoltage lockout. Certified to UL 62368-1 standards and backed by a 3-year manufacturer warranty, the DDR-15G-12 is an exceptionally reliable choice for industrial control, wireless networking, and automation systems.
