When it may not be suitable
This power supply may not be suitable for indoor applications where space is extremely limited, as its hermetic casing is larger than standard non-waterproof drivers. Additionally, it is not intended for use in environments where the ambient temperature exceeds the manufacturer's specified operating range, as this could lead to thermal shutdown or reduced lifespan.
Key specifications
Output voltage: 12V DC
Power rating: 100W
Ingress protection: IP68
Application: Outdoor and wet environments
Design: Hermetic, fully sealed
How to use
Installation should be performed by a qualified professional to ensure all electrical connections are properly sealed and protected. Connect the input side to the AC mains supply according to local electrical codes, ensuring the correct polarity. Connect the output side to your 12V LED lighting system, maintaining correct polarity to prevent damage to the LEDs. Ensure that the total power draw of the connected LED load does not exceed the 100W capacity of the power supply to prevent overloading.
What to consider before purchase
Verify the total wattage of your LED system to ensure it does not exceed 100W
Confirm that the 12V DC output matches the requirements of your LED strips
Ensure the installation location allows for adequate heat dissipation despite the IP68 rating
Check that all cable connections are made using waterproof connectors to maintain the IP68 integrity
Usage recommendations
For optimal performance and longevity, it is recommended to operate the power supply at approximately 80% of its maximum rated load. Always ensure that the unit is installed in a position that allows for natural airflow, even if it is waterproof, to prevent excessive heat buildup during extended periods of operation.
