MEAN WELL LRS-450-24 Switching Power Supply

AzarPixel is introducing the renowned enclosed type of power supply, the MEAN WELL LRS-450-24, which provides 451.2W of power by delivering a stable 24VDC output at 18.8A with a typical efficiency of 91% for your industrial applications or electronic instruments and equipment.

With a built-in fan that switches on when the temperature reaches 50°C and off at 40°C, the unit can operate over a -20°C to +70°C temperature range, and its low-profile 1U enclosure fits cleanly into tight panel installations and high-vibration industrial environments.

It supports both 100 to 120VAC (10A) and 200 to 240VAC (6A) AC input ranges (must be set correctly before powering on) and features a built-in potentiometer that allows users to fine-tune the output voltage within a range of 22.8 to 26.4V to match the exact requirements of their load.

The LRS-450-24 includes protection against short circuits, overload (105 to 150% rated power, shut down after 3 seconds), over voltage (27.6 to 32.4V), and over temperature. For instrument safety, this unit will shut down when any fault or protection is triggered and requires a manual re-power to reset. This prevents automatic restarts, ensuring that any system faults are acknowledged and solved before resuming operations.

For loads that regularly pushed the LRS-350-24 (350.4W / 14.6A) close to its current limit, the LRS-450-24 provides a comfortable margin, making it an ideal choice for systems requiring additional capacity without changing the overall installation approach.

This unit complies with international safety standards including UL62368-1, IEC60950-1, GB4943.1, EN61558-1, and EN61558-2-16, making the LRS-450-24 a reliable solution for industrial automation machinery, control panels, and electrical equipment that needs a dependable, high-current 24VDC power source.
