ATTE ASUC-50-480-OF Industrial DC/DC Converter 48V to 12V 4A 48W DIN Rail Mount

When a 48 VDC industrial control cabinet needs reliable 12 V power for sensors, controllers, or auxiliary equipment, the ATTE ASUC-50-480-OF keeps the line clean and protected. This compact DIN-rail converter steps down a 40–60 VDC input to a stable 12 V output at up to 4 A, handling 48 W with 88% efficiency. With comprehensive protection built in, it suits telecom, automation, and security installations where voltage spikes and short circuits can otherwise take down critical loads.

Who is it for

This converter is for panel builders, maintenance technicians, and system integrators working with 48 V battery banks or industrial power rails. It is ideal for powering CCTV cameras, access control systems, PLC I/O modules, sensors, and other low-voltage devices in a machine cabinet or network box. The DIN-rail format allows quick snap-on mounting next to breakers and power supplies.

Main features

• Wide 40–60 VDC input range accepts nominal 48 V systems with voltage fluctuation.
• Regulated 12 VDC output at up to 4 A (48 W) with low ripple below 100 mVp-p.
• 88% efficiency means less wasted heat in sealed enclosures.
• Protection against short circuit, overload, overvoltage, and reverse polarity.
• DIN rail TS-35 mounting with screw terminals for secure wiring.
• LED indicator confirms output voltage presence.
• Convection cooled, no fan required, operates from -10°C to +50°C.

Tips

Mount the converter on a DIN rail in a well-ventilated area of the enclosure to ensure proper convection cooling. For best performance, keep input and output wiring as short as possible and use appropriate wire gauges to minimize voltage drops. The LED indicator provides a quick visual check of output status, making troubleshooting easier during commissioning or maintenance.
