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”. The power
supply does not shut down but goes in 2
nd
level regulation at 30-
32 Vdc and continue to deliver the power. According to high output
voltage which will be operating > 100% of rated load (32 V × rated
output current), if this condition persists, the power supply will
sense OTP (Over Temperature Protection) and will go under
hiccup mode. The power will return to normal operation once the
fault condition is removed.
Over Temperature Protection (Auto-Recovery)
As mentioned above, 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.
