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 ±5% of its
steady state value, when subjected to a dynamic load from 10 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 at the L pin, with an internal fuse that cannot be replaced. The power supply 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 of 10A B- or 8A 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 200% of maximum rated load
(IOMax), for a maximum duration of 2
seconds, or 150% of maximum rated load
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 (IO) exceeds its
specification as defined on Page 3 under “Protections”. In such
occurrence, the output voltage (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 IOis back
within the specifications.
It is not recommended to prolong the duration of IOwhen it is less
than OLP/OCP point, but greater than 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 mentioned above, 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
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 0.45~0.50V for 24V 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. 4 Redundant Operation Connection Diagram
Parallel Operation
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.

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.
