MEAN WELL HLG-600 & HEP-600: What’s the Difference?

When it comes to industrial power supplies, MEAN WELL offers a range of solutions tailored to different needs. Two prominent models in their lineup are the MEAN WELL HEP-600 and MEAN WELL HLG-600 series. While both provide robust power solutions, they are designed for distinct applications and environments. This article highlights their differences, voltage options, dimming capabilities, and necessary certifications for the Australian market.

MEAN WELL HEP-600: Built for Harsh Environments 

The MEAN WELL HEP-600 series is engineered to withstand extreme conditions, making it ideal for industrial environments where durability is paramount. Key features include: 

• High Efficiency: Up to 96% efficiency, ensuring minimal energy loss. 
• Durability: Encased in aluminium and filled with heat-conducted silicone, the MEAN WELL HEP-600 is resistant to high temperatures, humidity, dust, and vibration. 
• Voltage Options: Available in 12V, 15V, 20V, 24V, 30V, 36V, 42V, 48V and 54V variants, with adjustable output voltage through an internal potentiometer. 
• Applications: Suitable for outdoor telecommunication equipment, electronic signage, industrial environments, petroleum plants, and mine shafts. 

While the MEAN WELL HEP-600 does not have built-in dimming capabilities, it allows for power output adjustments via external control systems or internal settings, providing flexibility for various industrial applications. 

MEAN WELL HLG-600: Optimized for LED Lighting 

The MEAN WELL HLG-600 series is primarily designed as an LED driver, offering both constant voltage and constant current modes. Its features include: 

• High Efficiency: Also up to 96% efficiency, ensuring effective power usage. 
• IP Rating: With an IP65/IP67 rating, the MEAN WELL HLG-600 is suitable for both indoor and outdoor applications. 
• Voltage Options: Available in a wide range of voltages, including 12V, 15V, 20V, 24V, 30V, 36V, 42V, 48V, and 54V. 
• Dimming Capabilities: Models like the MEAN WELL HLG-600H-B include a 3-in-1 dimming function (1-10VDC, PWM signal, or resistance), allowing for direct dimming control without additional components. 
• Applications: Commonly used in LED lighting systems, such as high-bay lighting, parking space lighting, and LED fishing lamps. 

Certifications for Australian Users 

To ensure compliance and safety, both the MEAN WELL HEP-600 and MEAN WELL HLG-600 series need to meet several certifications for use in Australia: 

• Electrical Equipment Safety System (EESS): Mandatory certification for electrical equipment safety. 
• CE Marking: Indicates conformity with health, safety, and environmental protection standards. 
• UL Certification: Ensures adherence to safety standards for electrical devices. 
• IEC 62368-1: International safety standard for audio/video, information, and communication technology equipment. 
• CB Scheme: Facilitates international certification, ensuring compliance with Australian standards. 

What's the difference?

The MEAN WELL HEP-600 and MEAN WELL HLG-600 power supplies cater to different industrial needs. The MEAN WELL HEP-600 is perfect for harsh environments, offering high durability and adjustable power output, while the MEAN WELL HLG-600 excels in LED lighting applications with its extensive voltage options and built-in dimming capabilities. Ensuring these power supplies meet the necessary certifications guarantees their safe and reliable use in the Australian market. 

Whether you need a power supply for rugged industrial settings or efficient LED lighting, MEAN WELL provides robust solutions tailored to your specific requirements.
