MEAN WELL DRS-240-12 fuente de alimentación para carril DIN 12V 20A 240W

Delivers 240W of clean 12V DC power at up to 20A from a compact DIN-rail module, accepting a wide 90–305VAC input for global industrial use.

Overview

The MEAN WELL DRS-240-12 is a single-output DIN-rail power supply engineered for industrial automation, building control, and machine applications. It converts a universal AC input into a regulated 12V DC rail with 20A maximum current, providing a total of 240W. The output voltage is adjustable from 10.8V to 15V to compensate for line drops or to match specific load requirements. With 90% efficiency and free-air convection cooling, the unit operates reliably across a wide temperature range from -30°C to +70°C.

What stands out

• Wide input range: 90–305VAC (127–431VDC) for use on nearly any mains supply.
• Adjustable output voltage: 10.8–15V DC for flexible system integration.
• Full protection: short circuit, overload, over voltage, and over temperature.
• High isolation: 3kVAC between input and output, 2kVAC input to ground.
• DIN-rail mountable on TS-35/7.5 or TS-35/15 rails.
• Certified to UL, CUL, TUV, CB, and CE.
