(1) An overvoltage shuts down the output. Recover by recycling a-c input (30 second delay required before resetting).
(2) See rating curves for temperature and input voltage derating.
(3) Square type for 50W and 300W models; hiccup mode operation for 100W and 150W models. After the cause of overcurrent is removed,
output recovers automatically.
(4) Bandwidth 100MHz. The ripple and noise values tabulated are valid when the output is derated as shown in rating curves from 40°C to 71°C.
(5) Peak current 10A, maximum duration 10 seconds.
