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 thesurrounding 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.

Inrush Current

Overload & Overcurrent Protections (Auto-Recovery)

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’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 105% ofIO (Max load). In such occurrence, the VO will start to droop andonce the power supply has reached its maximum power limit, theprotection is activated and the power supply will go into “Hiccupmode” (Auto-Recovery). The power supply will recover once thefault 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”.
The power supply should be latch.

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, theoutput current will operate in “Hiccup mode”, as shown in theillustration in the OLP/OCP section on this page. The power supply
will return to normal operation after the short circuit is removed.

12Additionally, if the IO is <105% but >100% for a prolong period oftime (depending on the load), the Over Temperature Protection(OTP) will be activated due to high temperature on criticalcomponents. The power supply will then go into latch mode until
the fault is removed and the mains is 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 theoperating 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.

Delta RoHS Compliant
Restriction of the usage of hazardous substances
The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead,mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical andelectronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances inelectrical and electronic equipment”.
This product conforms to this standard.

Conformal Coating
The Protective Coating Technology
Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including underdevice, and prevents leakage. The conformal coating dipping can be applied to PCBs or circuit board. The coatingpreserves 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 inhighly conversing atmosphere.
