(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 -10~0°C.
The ripple and noise values tabulated are valid when the output is derated as shown in Figure 1 from 50~65°C.
