Inrush Current
Surge Load
Inrush current is the peak, instantaneous, input current measured
and, 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.
It is the reserve power available constantly that allows reliable
startup of loads with high inrush current. After the output has
reached its steady state set value, the power supply can support
surge loads of up to 150% of maximum rated load (Io Max), for a
maximum duration of 5 seconds. The maximum allowed rate of
load change is 0.1amps per microseconds, and the voltage can
vary ±5% from the set value during the duration of the surge load.
Step Load Response
Overload & Overcurrent Protections
The power supply output voltage will remains within ±5% of its
steady state value, when subjected to a dynamic load from 10 to
100% of its rated current.
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current exceeds 150% of
IO (Max load). In such occurrence, the VO 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 IO is back
within the specifications.
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”.
Additionally, if the IO is <150% 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.
