Questions about this item

Will the internal fan in the L255ES-01 need replacement after long use?

The fan is built into the sealed 255W unit and is not user-serviceable; if it fails the entire module is replaced.

What thermal limit appears first when the L255ES-01 runs continuously at full load?

The 255W output ceiling is reached before any other constraint, triggering protection shutdown if exceeded.
