Note1: The device shall shutdown without latch-off if the input voltage goes down the specified limit.
Note2: The device has an internal over-current protection. A delayed-blow, high breaking capacity fuse
(not accessible) is placed in the line side of the input circuit.
Note3: The device has an internal inrush current protection. A NTC resistor (not accessible) is placed in
the line side of the input circuit.
Note4: Maximum steady-state output current obtainable from the regulated output.
Note5: The device shall not be damaged when input power is applied with an output over-current. During
this condition the device produces a “LEAN FORWARD MODE” working.
Note6: The device shall not be damaged when input power is applied with an output short circuit (less
than 0.1 ohm). During this condition the device produces an “LEAN FORWARD MODE” working.
Note7: The device shall shutdown with latch-off the output. It is necessary to remove the mains supply
and restart the device (the output voltage never exceeds 35V).
Note8: When the output voltage goes down specified value, the device shall shutdown without latch-off the
output.
Note9: When the junction temperature reaches specified value the controller IC shall shutdown and
protects other components from failure. The temperature protection is not latching; after an over-
temperature shutdown, the controller will restart as temperature drops.
LEAN FORWARD MODE
= the equipment permits the current to be increased
by a factor 1.7 of the maximum rated value, and slowly reduces the
output voltage (up to 0 volts, during short-circuit). This increased
current is permanently available, so that the device neither switches-
off nor hiccups as a result of overload or short-circuiting.
