10 Reset Time
Note 1: The device shall shutdown without latch-off if the input voltage goes down the specified limit. This value is measured at full load.
Note 2: The device has an internal over-current protection. A slow-blow, high breaking capacity fuse (not accessible) is placed in the line side of the input
circuit.
Note 3: The device has an internal inrush current protection. A NTC resistor (not accessible) is placed in the line side of the input circuit.
Note 4: The device shall not be damaged when input power is applied with a short-circuit (about 0.01 ohm) from the output voltage to its return. During
this condition the device produces a constant output current.
Note 5: Maximum steady-state output current obtainable from the regulated output (Vth = Vrated – 3% = 11.64Vdc).
Note6: The device shall not be damaged when input power is applied with an output over-load. During this condition the device produces a “LEAN-
FORWARD MODE” working.
Note 7: When the output voltage exceeds specified value the device shall shutdown without latch-off and goes in the burst mode operation. During burst
mode the output voltage pulses with peak value of about 17V.
Note 8: When the output voltage goes down specified value the device shall shutdown without latch-off the output.
Note 9: 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.
Note 10: If the device latches-off due to a fault condition, it shall return to normal operation only after the fault has been removed and the supply is reset.
Duration of the off-time necessary to reset the device must be at least as shown.
(*) LEAN-FORWARD MODE
The equipment permits the current to be increased by a factor 1.4 of the maximum rated value, and
slowly reduces the output voltage (up to the full short-circuit). The short-circuit current can be supplied
indefinitely, without damage the power supply.
