HLG-150H-48A - 48V 150W PFC Power Supply - IP65 Metal Industrial LED/Automation

Product Specification

1. ​Product Overview​

The MEAN WELL HLG-150H-48A is a high-efficiency, IP67-rated LED driver/power supply engineered for demanding industrial and outdoor applications. Combining ​150W output​ at ​48V DC nominal voltage​ (adjustable 43.2-52.8V), this unit delivers reliable constant voltage/current operation with a peak efficiency of ​95%​. Its cast aluminum housing provides exceptional thermal management and environmental protection against dust, moisture, and chemical exposure. Featuring universal ​90-305V AC input​ (47-63Hz), it operates globally without voltage switching. Integrated protections include short-circuit, over-voltage, over-temperature, and surge protection (4kV L-N). The compact design (215×65×40mm) enables space-efficient installations in control cabinets, machinery, and harsh environments (-40°C to +90°C operating range).

2. ​Key Technical Parameters​

  • Operating Temp: -40°C to +90°C (full power to +70°C)
  • Humidity: 5-95% RH non-condensing
  • Vibration: 5G @ 10-500Hz (IEC 60068-2-6)
• ​Certifications:
  • UL/cUL 8750, ENEC/EN 61347-1, IP67 (IEC 60529)
  • CE, RCM, FCC Class B, BSMI

3. ​Primary Applications​

This power supply excels in critical industrial scenarios:

• ​Industrial Automation: PLC control panels and HMI backlighting
• ​Outdoor LED Lighting: Streetlights, floodlights, and signage requiring IP67
• ​Telecom Infrastructure: Base station equipment and 5G small cells
• ​Renewable Energy: Solar-powered monitoring systems
• ​Material Handling: Conveyor control systems in warehouses
• ​Food Processing: Washdown-area machinery (NSF/3-A compliant options)
• ​Transportation: EV charging station displays
• ​Medical Equipment: Diagnostic imaging cabinet lighting
  The wide temperature range (-40°C cold start) makes it ideal for arctic mining operations and desert solar farms, while IP67 protection ensures reliability in food/beverage CIP environments.

4. ​Functional Advantages​

• ​Extreme Environment Resilience:
  • Operates submerged (1m/30min per IP67)
  • Withstands high-pressure washdowns (100 bar)
• ​Energy Efficiency:
  ≤0.5W no-load consumption
  2x lower heat dissipation vs. conventional supplies
• ​Installation Flexibility:
  Terminal block accepts 12-22 AWG wiring
  Wall/panel/DIN-rail mounting options
• ​Long-Term Reliability:
  300,000-hour MTBF (MIL-HDBK-217F)
  7-year warranty coverage
• ​Safety Compliance:
  Reinforced insulation (3,750V AC isolation)
  Conformal-coated PCB (IPC-CC-830B)
• ​Smart Control Integration:
  DALI-2 gateway compatibility
  Dim-to-off function (≤1% output)

5. ​Advanced Operation Features​

The HLG-150H-48A employs ​active PFC (0.99 typical)​​ with resonant LLC topology for minimal switching losses. Dimming functionality operates via:

1. ​0-10V Analog: Linear 1.5-10V = 10-100% output
2. ​PWM Control: 100Hz-3kHz (10-100% duty cycle)
3. ​Resistive Dimming: 100kΩ potentiometer
   Thermal management utilizes ​multi-stage protection:

• ​Stage 1: Output derating above +70°C case temp
• ​Stage 2: Hiccup mode activation at +100°C
• ​Stage 3: Complete shutdown at +120°C (auto-recovery)
  Built-in ​surge protection​ includes:
• Line-to-Neutral: 4kV (IEC 61000-4-5)
• Line-to-Ground: 6kV
  Output current limiting maintains ±3% regulation during 150% overloads. The aluminum casing acts as a heatsink, enabling convection cooling without fans – critical for dust-sensitive environments.
