LED module compatibility and load selection
Choose a power supply for the LED board’s specified voltage and load. A 4.5V model should not be selected solely because its housing resembles a 5V supply. Check the terminal arrangement and mounting drawing as well as the electrical ratings.
The datasheet calls for load allowance and temperature derating. It also specifies an auxiliary 400 × 400 × 3mm aluminum plate for full-load use. Review these installation conditions when planning cooling inside an enclosed cabinet.

Frequently asked questions
Is the A-200AF-4.5 a 200W power supply?
The exact A-200AF-4.5 entry in the series specification is rated at 180W. The A-200AF-5 entry is rated at 200W.
Can this power supply run a 4.5V LED board?
It provides 4.5V DC. Check that the board requires this voltage and that the combined load, wiring and installation conditions suit the supply.
Does the A-200AF-4.5 have a cooling fan?
No. The specified cooling method is free air. Provide the heat dissipation required by the datasheet, including its full-load installation conditions.
Does it support 110V mains?
Its specified input range is 180–264VAC. Do not use this rating as evidence of 110V compatibility.
