\n

A switching power supply needs a minimum load only when its model-specific operating requirements call for one.<\/strong> For a single-output industrial AC-DC supply, check the documented output-current range and any minimum-load conditions, then verify the equipment\u2019s unloaded, idle and return-to-load states. A 0 A lower limit is useful documentation; it does not, by itself, establish every ripple, transient or environmental limit your equipment needs.<\/p>\n
