MEAN WELL LRS-100-5 Alimentatore switching chiuso 90W 5V 18A

Delivering 90 watts of reliable DC power from a compact metal enclosure, the MEAN WELL LRS-100-5 is a single-output switching power supply built for industrial and automation applications. With a 5V output at up to 18A, it efficiently converts a universal AC input into clean, regulated DC power.

Overview

The LRS-100-5 accepts a wide input voltage range of 85 to 264 VAC (or 120 to 370 VDC), making it suitable for use worldwide without the need for voltage selection switches. Its high efficiency of 85% reduces energy waste and heat generation, while free air convection cooling eliminates the need for a fan, ensuring silent operation and long-term reliability.

What stands out

• Compact metal case with chassis mount screw terminals for secure installation.
• Adjustable output voltage from 4.75V to 5.5V to compensate for voltage drops in long cable runs.
• Comprehensive protection against short circuits, overload, and overvoltage.
• Wide operating temperature range from -30°C to +70°C, suitable for harsh environments.
• Low ripple and noise (80mVp-p) ensures stable power for sensitive electronics.
