Functions
Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
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.
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 remains within ±2% of its
steady state value, when subjected to a dynamic load from 0% to
100% of its rated current.

It is not recommended to prolong the duration of Power Boost to be longer than the specified duty cycle calculation, this may cause
damage to the PSU.
External Input Protection Device
The unit is protected with internal fuse (not replaceable) at L pin and it has been tested and approved on 20A (UL) and 16A (IEC)
branch circuits without additional protection device. An external protection device is only required if the supplying branch has an
ampacity greater than above. Thus, if an external protective device is necessary, or, utilized, please refer a minimum value in
instruction sheet with B or C characteristic breaker.
Power Boost is the reserve power available
constantly that allows reliable startup to support
sudden and short spike of loads with high inrush
current typically during turn on to remove the
need of more expensive higher rated power
supply unit. After the output has reached its
steady state set value, the power supply can
support surge loads with a higher short-term
power demand up to 150% of maximum rated
load (IOMax), for a maximum duration of 5
seconds. The Power Boost is also available to
repeatedly basis with according to the condition of
an average (R.M.S) output power shall not
exceed continuous operating condition or refer to
duty cycle calculation below.

Overload & Overcurrent Protections (Auto-Recovery)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 150%
of IO(Max load). In such occurrence, the VOwill 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 IOis back
within the specifications.
It is not recommended to prolong the duration of IOwhen it is
<150% 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 (Auto-Recovery)
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”.
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.

Operating Mode
Redundant Operation
Parallel Operation
In order to ensure proper redundant operation for the
power supply unit (PSU), the output voltage difference
between the two units must be kept at 0.90~1.00V for 48V
supplies. Follow simple steps given below to set them up
for the redundant operation:
Step 1.
Measure output voltage of PSU 1 and PSU 2. If PSU 1 is
the master unit, then VOof PSU 1 must be higher than
PSU 2. In order to set the output voltage, individually
connect the power supply to 50% of rated load at any line
voltage from 85-264Vac, and set the PSU 1 and PSU 2
output voltage.
Step 2.
Connect the power supply units PSU 1 and PSU 2 to Vin 1
& Vin 2, respectively, of the DRR-20N (or 20A) module
shown on the diagram on the right.
Step 3.
Connect the system load from Vout. Please note that
output voltage Vout from DRR module will be = VO(output
voltage of power supply) – Vdrop* (in DRR module).
*Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the
load current and surrounding air temperature
**The Signal GND in the DRR module is for the built-in LED and DC OK signals. The Output
GND terminals from the two PSU’s do not need to be connected to the Signal GND terminal.
Fig. 3 Redundant Operation Connection Diagram
The power supply units (PSUs) can also be used for
parallel operation in order to increase the output power.
The difference in output voltage between the two units
must be kept to within 25mV of each other. This
difference must be verified with the same output load
connected independently to each unit.
Parameters such as EMI, inrush current, leakage current,
PARD, start up time will be different from those on the
datasheet, when two units are connected in parallel. The
user will need to verify that any differences will still allow
the two power supplies connected in parallel will work
properly in their product/application.

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.
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 PCBAs 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.
PFC – Norm EN 61000-3-2
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.
