MEAN WELL DDR-15L-12 Conversor DC-DC para calha DIN 15W 12V 1,25A

Industrial control systems often face unstable DC input voltages, leading to equipment malfunction or failure. The MEAN WELL DDR-15L-12 is a robust DIN rail DC-DC converter that steps down a wide 18-36 VDC input to a stable 12 VDC output, delivering up to 15 W of power. It ensures reliable operation for sensitive electronics in harsh environments.

Who is it for

This converter is ideal for system integrators, panel builders, and maintenance engineers who need a compact, efficient power solution for industrial automation, instrumentation, and control cabinets. It suits applications where a 24 VDC battery or bus voltage must be converted to 12 VDC for sensors, controllers, or communication devices.

Main features

• Wide DC input range: 18 - 36 VDC, compatible with 24 VDC systems
• Stable 12 VDC output with 1.25 A rated current and 15 W power
