Maximum Output Power
Maximum output power states the greatest electrical power a supply or conditioning unit is specified to deliver to connected equipment.
The operating conditions and scope of the rating matter: a total rating may be shared across several outputs. Continuous and short-duration ratings should remain distinct.
Maximum Output Power — Power Supply
For an external power supply, available power must be considered with its output voltage and current limits. With multiple outputs, the maximum may describe their combined capacity rather than the capacity available from each connection.
Compare the required device supply with the stated voltage, current, polarity and connector as well as wattage. Equal power ratings do not make different supplies interchangeable. Check whether all outputs can deliver their individual ratings simultaneously or whether they share a total limit.
Maximum Output Power — Power Filter
For a power filter, this rating limits the load supplied through the filter to connected components. It does not describe the audio power those components deliver to their speakers.
Compare the permitted total load and any outlet-group limits under the stated mains conditions. Keep watts distinct from volt-amperes when the published rating uses apparent power. A high outlet count does not multiply the filter’s maximum capacity, and brief surge handling is a separate specification.
