BrightLink 75W 24V Enclosed Power Supply — LRS-75 Series Compatible

Compact, efficient, and remarkably affordable — the BrightLink BL-LRS75 packs 75W of reliable 24VDC power into an enclosure measuring just 99×97×30mm. Built as a direct substitute for the Mean Well LRS-75-24, this power supply fits into the same tight spaces inside light fixtures, sign cabinets, and control panels where every millimeter counts.

The LRS series architecture prioritizes simplicity and reliability: a single-output, non-PFC design that delivers excellent efficiency (90%) with minimal component count. Fewer components means fewer failure points, making the BL-LRS75 an ideal choice for applications where cost-effective reliability matters more than advanced features.

Key Features & Benefits

  • Ultra-Compact 30mm Profile — At only 30mm deep, the BL-LRS75 fits inside slim LED panels, narrow sign boxes, and crowded electrical enclosures where taller power supplies simply won’t go.
  • 90% Efficiency, Fanless Design — Natural convection cooling eliminates fan noise and removes a common failure point. Low heat dissipation reduces thermal stress on surrounding components.
  • Universal AC/DC Input — Accepts 85-264VAC or 120-373VDC, compatible with both AC mains and DC bus systems. One SKU covers global deployments.
  • 300VAC Surge Withstand — Handles 5-second surge events up to 300VAC, providing resilience against grid switching transients common in commercial buildings.
  • Full Protection Package Despite its budget-friendly cost, the BL-LRS75 includes short circuit, overcurrent, and overvoltage protection — all operating autonomously with automatic recovery.
  • 5G Vibration Resistance — Tested to withstand 5G vibration per IEC 60068-2-6, suitable for installation in vehicles, machinery, and locations subject to mechanical shock.

  • Automation & Control Panels — DIN-mountable with optional adapter, suitable for powering 24V PLCs, sensors, and relay modules in industrial control cabinets.

Installation Notes

Mount the BL-LRS75 on a flat surface using the 4 mounting holes on the base plate, or install inside an enclosure using the integrated mounting clips. Connect AC input to the terminal block (L/N/⏚). Output connects via the DC terminal block (+V/-V). Adjust output voltage ±10% using the onboard trim pot (V ADJ) if fine-tuning is needed. Ensure at least 10mm clearance above and below for airflow.
