Power De-rating
Functions
Start-up Time
The time required for the output voltage (Vo) to reach 90% of its set value, after the input AC voltage is applied.
Rise Time
The time required for the output voltage (Vo) to change from 10% to 90% of its steady state value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time
required for the output to reach 95% of its set value, after the input voltage is removed.

Dynamic Response
Inrush Current
Inrush current is the input current that occurs when the input
voltage is first applied. For AC input voltages, the maximum peak
value of inrush current will occur during the first half cycle of the
applied AC voltage. This peak value decreases exponentially
during subsequent cycles of AC voltage.
Overvoltage Protection
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”. Power
supply will latch mode, and require removal/re-application of input
AC voltage in order to restart.
Short Circuit Protection
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.
Overload & Over current Protections
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current is between
110% and 170% of IO (Max load). Upon such an occurrence, VO
will start to drop. Once the power supply has reached its
maximum power limit, the protection will be activated. and the
power supply will go into “Hiccup mode” (Auto-Recovery). The
power supply will recover once the fault condition causing the
OLP and OCP is removed and IO is back within the specified limit.
Additionally, if the IO is <110% but >100% for a prolong period of
time (depending on the load), the Over Temperature Protection
(OTP) will be activated due to high temperature on critical
components. The power supply will then go into hiccup mode until
the fault is removed; and, the input voltage is removed, then
reapplied.
Over Temperature Protection
As mentioned above, the power supply also has Over
Temperature Protection (OTP). This is activated when the
overload condition persists for an extended duration and the
output current is below the overload trigger point but >100% load.
In the event of a higher operating condition at 100% load, the
power supply will run into OTP when the surrounding air
temperature is higher than the operating temperature. When
activated, the output voltage will go into hiccup mode until the
input voltage is removed; then, reapplied, and the surrounding air
temperature drops to its normal operating temperature.
