The LNE-48V320WAAA is a 48V 320W LED driver designed for high-efficiency LED lighting systems in both indoor and outdoor environments. It delivers a nominal output voltage of 48Vdc at 6.70A with an adjustable voltage range of 43.0–53.0V and current adjustment range of 3.35–6.70A, enabling precise control of LED brightness and operation. The driver achieves up to 94.5% efficiency at 230Vac and 277Vac input, incorporates active power factor correction (PFC) meeting IEC/EN 61000-3-2 Class C, and provides exceptional surge immunity with 6kV common mode and 4kV differential mode protection. It features IP65 protection with potentiometers for voltage and current adjustment, operates across a wide input range of 90–264Vac (ENEC/CE/CCC approval) or 90–305Vac (UL approval), and includes comprehensive protections including overvoltage latch mode (55.2–67.2V), overcurrent limiting, and over-temperature hiccup mode with auto-recovery. With an MTBF exceeding 700,000 hours and compliance to international safety standards (UL 8750, EN 61347-1/2-13, IEC 61347-1/2-13), this driver is ideal for energy-efficient LED lighting solutions requiring reliable long-term operation in demanding environments.
