Inrush Current

Inrush Current is the first surge current seen on the input side

when AC input is applied to the power supply. It is the first pulse

captured; see a typical picture for the inrush current as seen in

the power supply.

Dynamic Response

The power supply output voltage will remains within ±5% of its

steady state value, when subjected to a dynamic load from 0 to

100% of its rated current.

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”.

Overload & Overcurrent Protections

The power supply’s Overload (OLP) and Over current (OCP)

Protections will be activated when output current exceeds 120%

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

within the specifications.

<120 but >100%, since it may cause damage to the PSU.

Over Temperature Protection

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.

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.
