MW MEAN WELL DDR-480B-48 convertitore DC/DC 48V 10A 480W guida DIN

Industrial systems often face unstable DC input voltages that can damage sensitive equipment. The MW MEAN WELL DDR-480B-48 DC/DC converter solves this by converting a wide 96–144 VDC input into a stable 48 VDC output, ensuring reliable power for your critical devices.

Who is it for

This converter is ideal for engineers and technicians working with industrial automation, railway systems, or renewable energy installations that require a regulated 48 VDC supply from a higher-voltage DC bus. It suits DIN rail mounting in control cabinets.

Main features

• High efficiency up to 92% reduces energy waste and heat generation.
• Wide input range 96–144 VDC accommodates fluctuating DC sources.
