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).

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:
- 0-10V Analog: Linear 1.5-10V = 10-100% output
- PWM Control: 100Hz-3kHz (10-100% duty cycle)
- 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.
