Safety Instructions
– If the device has to be mounted in any other orientation, please contact info@deltapsu.com for more details.
– The device is not recommended to be placed on surface with low thermal conductivity, such as plastics, for example.
– For safety reasons, please ensure the mounted device is kept at ≥ 4mm (0.16 inch) safety distance at all sides from other
components and equipments. Please insert an insulation sheet between the system and product, if the safety distance is less than
4mm. In addition, to ensure sufficient convection cooling, always maintain a distance of ≥ 20mm (0.79 inch) from ventilated
surfaces while the device is in operation.
– Note that 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; Product failure
– 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
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.
Dynamic Response
The power supply output voltage will remain within ±5% of its
steady state value, when subjected to a dynamic load from 50 to
100% of its rated current.

Overload & Overcurrent Protections (Auto-Recovery)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 140%
of I
O
(Max load). In such occurrence, the V
O
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 I
O
is back
within the specifications.
It is not recommended to prolong the duration of I
O
when it is
<140% but >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.
Overvoltage Protection (Latch Mode)
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.
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.
Others
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 and
electronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in
electrical and electronic equipment”.
This product conforms to this standard.
