MEAN WELL HLG-480H Series: 480W Constant Voltage + Constant Current LED Driver

Overview

The MEAN WELL HLG-480H series is a 480W AC/DC LED driver that offers both constant voltage (CV) and constant current (CC) output modes. Designed for versatility, it operates from a wide input voltage range of 90~305VAC and provides models with rated voltages from 24V to 54V. With high efficiency up to 95.5% and a fanless design, it can operate in case temperatures from -40°C to +90°C under free air convection. The robust metal housing and IP67/IP65 ingress protection make it suitable for both indoor and outdoor applications. The series supports various dimming functions for optimal design flexibility in LED lighting systems.

Specifications Summary

Electrical Characteristics

The HLG-480H series operates in either Constant Voltage or Constant Current mode. The output characteristics vary depending on the specific model and function options.

• Constant Current Region: Adjustable via built-in potentiometer for A/AB types.
• Voltage Adjustment Range: Adjustable for A/AB types via built-in potentiometer.
• Voltage Tolerance: ±1.0%
• Line Regulation: ±0.5%
• Load Regulation: ±0.5%
• Setup, Rise Time: 500ms, 80ms at 115VAC/230VAC
• Hold Up Time (Typ.): 16ms at 115VAC/230VAC

Dimming Operation

The HLG-480H series supports various dimming methods:

• 3-in-1 Dimming (for B/AB-Type): Output current can be adjusted using 0~10VDC, 10V PWM signal, or resistance. The dimming input is applied between DIM+ and DIM-. The dimming level is proportional to the input signal. A graph illustrates the relationship between dimming input (voltage or resistance) and output current.
• Smart Timer Dimming (for Dxx-Type): This feature allows for pre-programmed dimming profiles over time, supporting up to 14 consecutive hours. Examples provided include profiles for residential lighting (D01-Type), street lighting (D02-Type), and tunnel lighting (D03-Type), each with specific time and dimming level settings. These profiles can be configured using MEAN WELL's software.

Note on Dimming:

• Minimum dimming level is approximately 6%. Output current is not defined when the input is below 6%.
• Output current can drop to 0% with dimming inputs of 0kΩ, 0Vdc, or 0% duty cycle PWM signal.
• Ensure DIM- is not connected to Vo-.

Performance Graphs

Several graphs illustrate the performance characteristics of the HLG-480H series:

• Output Load vs Temperature: Shows derating curves for ambient temperature (Ta) and case temperature (Tc) at different input voltages (115VAC, 230VAC, and above 230VAC). It highlights that for constant current mode with rated current, the maximum workable ambient temperature (Ta) is 60°C (Typ. 230VAC).
• Static Characteristics: Displays the relationship between input voltage and load percentage.
• Power Factor (PF) Characteristic: Shows PF versus load percentage at 75°C case temperature for constant current mode, across different input voltages (115VAC, 230VAC, 277VAC).
• Total Harmonic Distortion (THD): Illustrates THD versus load percentage for the 42V model at 75°C case temperature, across different input voltages.
• Efficiency vs Load: Demonstrates the high efficiency (up to 95.5%) of the HLG-480H series across various load percentages and input voltages.
• Lifetime: A graph showing the estimated lifetime in thousands of hours (Kh) versus case temperature (Tc). It indicates that the product can achieve over 62,000 hours at a case temperature of 75°C or less.
