Information on MEAN WELL DDR-15G-3.3
The MEAN WELL DDR-15G-3.3 is an ultra-compact 11.6 W DIN-rail DC/DC converter engineered for seamless mounting on 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 inside control cabinets. Designed with a flexible 4:1 ultra-wide input voltage range of 9 to 36 V DC, it provides a stable regulated 3.3 V DC output at up to 3.5 A current. The output voltage can be adjusted between 3.0 V and 3.6 V via an onboard potentiometer to compensate for cable voltage drops, and the unit requires no minimum load to maintain stable operation.
Boasting a high efficiency rating of up to 85%, this converter relies on fanless free air convection to operate reliably across a broad operating temperature range of -40 °C to +85 °C. Strong safety isolation is guaranteed by its 4 kV DC reinforced I/O isolation, which protects downstream electronics from transient disturbances. Equipped with comprehensive protections against short circuits, overloads, overvoltages, input reverse polarity, and input undervoltage lockout, the module complies with UL 62368-1 standards. Backed by a 3-year manufacturer warranty, the DDR-15G-3.3 is an ideal solution for industrial control systems, telecom infrastructure, and automation equipment.
