Questions about this item

How often will the internal components need servicing?

Linear supplies like the RS-4A have no fan and few moving parts, so they typically run for years without internal maintenance beyond occasional dust removal.

What limits continuous output before the unit shuts down or throttles?

The supply is rated for 3 A continuous; drawing more than that for extended periods will trigger its protection circuitry.
