Power supply components may degrade, or
be damaged, when the power supply is
continuously used outside the shaded region,
refer to the graph shown in Fig. 1.
If the output capacity is not reduced when the
surrounding air temperature exceeds its
specification as defined on Page 3 under
“Environment”, the device will run into Over
Temperature Protection. When activated, the
output voltage will go into bouncing mode and
will recover when the surrounding air
temperature is lowered or the load is reduced
as far as necessary to keep the device in
working condition.
In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance as recommended in the
safety instructions while the device is in
operation.
Depending on the surrounding air temperature
and output load delivered by the power
supply, the device can be very hot!
If the device has to be mounted in any other
orientation,

If user’s mounting orientation is not according to the recommended mounting orientations, please consult Delta for further
information.
The device is not recommended to be placed on low thermal conductive surface. For example, plastics.
The enclosure of the device can become very hot depending on the ambient temperature and load of the power supply. Do not touch
the device while it is in operation or immediately after power is turned OFF. Risk of burning!
Do not touch the terminals while power is being supplied. Risk of electric shock.
Prevent any foreign metal, particles or conductors from entering the device through the openings during installation.
It may cause electric shock, safety hazard, fire and/or product failure.
Warning: When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device, remove
L and N connections before removing the Earth connection. The power supply must be mounted by metal screws onto a grounded
metal surface. It is highly recommended that the Earth terminal on the connector be connected to the grounded metal surface.

Functions
Start-up Time
The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied.
Rise Time
The time required for the output voltage to change from 10% to 90% of its final steady state set value.
Hold-up Time
Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.
■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Inrush Current
Dynamic Response
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.
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.

Overload & Overcurrent Protections (Auto-Recovery)
Overvoltage Protection (Latch Mode)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds
105-135% 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.
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 off, and require removal/re-application of input AC
voltage in order to restart.
It is not recommended to prolong the duration of IO when it is
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.
13
The power supply should be latch.
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.

Line Current Harmonic content
Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor.
In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying to
this standard can have some technical drawbacks, such as lower efficiency as well as some commercial aspects
such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard, therefore, it is
important to know whether it is mandatory to meet this standard for a specific application.
