Overload & Overcurrent Protections (Auto-Recovery)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current (I
O
) exceeds its
specification as defined on Page 3 under “Protections”. In such
occurrence, the output voltage (V
O
) will start to droop and once the
power supply has reached its maximum power limit, the protection
is activated and the power supply will go into “Hiccup mode” (Auto-
Recovery). The power supply will recover once the fault condition
of the OLP and OCP is removed and I
O
is back within the
specifications.
It is not recommended to prolong the duration of I
O
when it is less
than OLP/OCP point, but greater than 100%, since it may cause
damage to the PSU.
Short Circuit Protection (Auto-Recovery)
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied, the
output current will operate in “Hiccup mode”, as shown in the
illustration in the OLP/OCP section on this page. The power supply
will return to normal operation after the short circuit is removed.
Overvoltage Protection (Auto-Recovery)
The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications defined on Page 3 under “Protections”.
Over Temperature Protection (Auto-Recovery)
As described in load de-rating section, the power supply also has
Over Temperature Protection (OTP). In the event of a higher
operating temperature at 100% load, the power supply will run into
OTP when the operating temperature is beyond what is
recommended in the de-rating graph. When activated, the output
voltage will go into bouncing mode until the temperature drops to
its normal operating temperature as recommended in the de-rating
graph.
