LED-voeding Mean Well ELG-100-48-3Y, enkelvoudige uitgang 48V 2A, 100W, PFC

Mean Well ELG-100-48-3Y is a single-output LED power supply that provides a regulated 48 V DC output at up to 2 A with a total power rating of 100 W. Engineered for LED lighting installations, this model includes Power Factor Correction (PFC) to improve input efficiency and reduce harmonic distortion. The compact, ventilated housing and protective features make the unit suitable for indoor or protected outdoor installations where a stable constant-voltage 48 V source is required.

Advantages

The power supply offers a stable constant-voltage 48 V output with short-circuit and overcurrent protection to safeguard connected LED loads. Built-in Power Factor Correction improves AC-to-DC efficiency and reduces reactive power draw. The enclosure design provides ventilation and protection against dust and water splashes when installed in appropriate locations, while thermal management helps maintain reliable performance under varying load conditions.

Suitable for

• LED strip and module installations requiring 48 V constant-voltage supply
• Indoor or sheltered architectural and commercial lighting applications
• Signage and display lighting where stable output and protection features are required
• Lighting retrofit projects and centralized 48 V lighting systems

Key specifications

• Output voltage: 48 V DC constant-voltage
• Output current: up to 2 A
• Rated output power: 100 W
• Input: AC mains with Power Factor Correction (PFC)
• Protections: short-circuit protection, overcurrent protection, overvoltage protection, overtemperature protection
• Enclosure: ventilated housing suitable for indoor or protected outdoor use

How to use

Install the power supply in a location that meets the environmental protection guidelines for sheltered outdoor or indoor use, ensuring adequate ventilation and clearance around the housing. Connect the AC mains input following local electrical codes and ensure correct grounding. Connect the 48 V DC output to the LED load, observing correct polarity. Verify that the total LED load does not exceed the 100 W rating and that wiring and connectors are rated for the output current. After connection, power up and check that the output voltage is stable and that any status indicators on the unit show normal operation.

Recommendations

Use appropriate cable sizes and secure connections to minimize voltage drop at the 2 A output. Avoid installing the unit in fully exposed outdoor locations without additional enclosure protection. For long LED runs, calculate voltage drop and consider shorter runs or higher-gauge conductors. Observe manufacturer safety guidelines and local electrical regulations during installation and maintenance.
