MEAN WELL LRS-100-24 108W priemyselný spínaný napájací zdroj s jedným výstupom 24V DC 4,5A kovové puzdro

For automation and control panels that demand a stable 24V rail without fan noise or premature failure, the LRS-100-24 stands apart from typical open-frame units. Its fully enclosed metal case shields sensitive electronics from dust and accidental contact, while free-air convection cooling eliminates moving parts that wear out. The result is a power supply that can be mounted directly on a chassis or DIN rail adapter and forgotten for years.

Highlights

• 108W continuous output at 24V DC with 4.5A current
• Wide 85–264VAC input range with 120–370VDC option
• High efficiency up to 89% and low no-load consumption <0.3W
• Built-in overload, overvoltage, and short-circuit protection
• Compact metal enclosure, chassis mount, -30°C to +70°C operation

In daily use

Technicians appreciate the LRS-100-24 for its straightforward integration. The output voltage can be fine-tuned from 21.6V to 28.8V via the built-in potentiometer, compensating for voltage drop in long cable runs. The hiccup-mode overload protection automatically recovers after a fault is cleared, reducing downtime in unattended installations. With 3.75kVAC isolation between input and output, it safely powers low-voltage circuits in industrial machinery, LED lighting arrays, and test benches.
