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.
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
(IO Max), 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
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 200%
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.
It is not recommended to prolong the duration of IO when it is
<200% but >100%, since it may cause damage to the PSU.
Short Circuit Protection
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
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
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
Redundancy Operation
In order to ensure proper redundancy operation for the power supply unit (PSU), ensure that the output voltage difference between the
two units is kept at 0.45~0.50V for 24V supplies. Follow simple steps given below to verify:
Step 1.
Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the master unit, then VO of PSU 1 must be higher than PSU 2.
In order to set the output voltage, connect the power supply to 50% load and set the PSU 1 and PSU 2 output voltage.
Step 2.
Connect the right DRR module, 40A as per the system requirement to the power supply units PSU 1 and PSU 2 at Vin 1 & Vin 2
respectively.
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).
Parallel Operation
These DRR modules can also be used for Parallel function in order to increase the output power by N+1 (e.g. 2.5A + 2.5A = 5A or 2.5A
+ 2.5A + 2.5A = 7.5A) or current sharing, and thus increasing the power supply and system reliability. Though the DRP024V480W1B
is not designed for current sharing, a good current sharing between two power supplies can be achieved by following simple steps as
below (Refer to Fig. 3 for the Connection Diagram).
Step 1.
Set output load condition for both supplies at 50% and measure
the output voltages.
Step 2.
Adjust output voltages to the same level or within ±25mV
difference.
Step 3.
Connect PSU 1 and PSU 2 with the DRR-40A module and
measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure
the voltages are within ±25mV.
Step 4.
Output voltage from DRR module Vout 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.

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
