Overview
The MEAN WELL DDR-15L-12 converts a DC supply between 9 and 36 V into a regulated 12 V output at up to 1.25 A (15 W), in a 17.5 mm wide DIN rail case. Its input and output are isolated to 4 kV DC, and it runs from -40 to +85 °C, subject to the derating curve in the datasheet.
Where it fits
Inside a control panel it takes power from an existing DC rail, such as a 24 V supply, and gives a regulated 12 V for devices that need it, without a second mains supply. The output can be trimmed between 9 and 13.2 V.
Choosing it
- Size it with headroom above the total load of the connected devices. Other voltages and power ratings in the DDR-15 series are listed on this page.
- Typical efficiency is 86%; ripple and noise stay within 60 mVp-p.
- At low input voltage or high temperature, check the derating curve in the datasheet.
Installation
MEAN WELL treats the converter as a component to be built into final equipment, so approvals and EMC performance are confirmed for the complete installation. Wiring, safety and EMC details are in the official datasheet linked below.
