Any excessive twisting or bending may
damage the device’s PCB. Please
handle the device with care.
The device is not recommended to be
placed on low thermal conductive
surfaces. For example, plastics.
Prevent any foreign metal, particles or
conductors from entering the device
through
the
openings
during
installation. It may cause: -Electric
shock; Safety hazard; Product failure.
The power supply must be mounted
by metal screws onto a grounded
metal

It
is
highly
recommended that the Earth

Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region,
refer to the graphs shown above.
If the output capacity is not reduced when the surrounding air temperature is more than the upper limit temperature, 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.
Depending on the surrounding air temperature and output load delivered by the power supply, the device housing can be very hot!
If the device has to be mounted in any other orientation, please do not hesitate to contact info@deltapsu.com for more details.

Dynamic Response
Short Circuit Protection
The power supply output voltage will remain within ±5% of its
steady state value, when subjected to a dynamic load from 0 to
50% and 50 to 100% of its rated current.
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 & Overcurrent Protections
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 105% 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.
Inrush Current
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.
Additionally, if the IO is 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 latch mode until
the fault is removed and the mains is reapplied.
Over Temperature Protection
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”.
The power supply should be latch.
10
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 latch mode until the mains is reapplied and the surrounding air
temperature drops to its normal operating temperature.
All parameters are specified at 25°C ambient and AC input unless otherwise indicated.

Conformal Coating
The Protective Coating Technology
Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including under
device, and prevents leakage. The conformal coating dipping can be applied to PCBs or circuit board. The coating
preserves the performance of precision electronic primarily by preventing ionizable contaminants such as salt
from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem especially in
highly conversing atmosphere.
