(1) An overvoltage shuts down the output. Recover by recycling a-c input.
(2) The current limit is rectangular. The 30W models have a "Winker" circuit. After the overload is removed, output is automatically restored.
(3) Bandwidth 100MHz. Ripple and noise will be approximately 1.5 times these values in the operating temperature range -10 to 0C.
The ripple and noise values tabulated are valid when the output is derated as shown in Ratings vs Temperature. from 50 to 65C.
(4) [ ] = Peak current (useful for motor start applications).
(5) These models include thermal protection: if overtemperature detected, output voltage is cut off. For 100W and 150W models, output voltage returns automatically after sufficient cooling; for 50W models, recover by cycling a-c input after sufficient cooling.
