When selecting the Power Supply, make sure the Power Reserve.
Reasons for Power Reserves:
Change in the power of the Power Supply under various Operating Conditions.
Overheating of the Power Supply at maximum load.
High reliability and long life.
Advisable reserve capacity:
In the Gridcase + 10%.
Waterproof (Metal) + 20%.
Waterproof (Plastic), Adapter + 30%.
Calculation of performance of the Power Supply for LED Strips:
Power LED Strip + Reserve = Power Supply Current
Example:
LED Strip 24 W at 5 m, a total of 25 m. Power 120 W
Grid Case: 132 W required
Waterproof (Metal): 144 W required
Waterproof (Plastic) Adapter: 156 W required
