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 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 set value.  
Hold-up Time  
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time  
required for the output to reach 90% of its set value, after the input voltage is removed.  
Inrush Current  
Dynamic Response  
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 output voltage will remains within ±5% of its  
steady state value, when subjected to a dynamic load from 0 to  
100% of its rated current.  
All parameters are specified at 25°C ambient unless otherwise indicated.

Power Boost  
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 (IO Max), 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  
Overvoltage Protection  
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 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.  
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.  
It is not recommended to prolong the duration of IO when it is  
<150% 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.  
All parameters are specified at 25°C ambient unless otherwise indicated.

Redundancy / Parallel Operation Connection Diagram  
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, 20A as per the system requirement to the power supply units PSU 1 and PSU 2 at Vin 1 & Vin  
respectively.  
2
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 DRP024V240W3B☐  
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 3.  
Step 1.  
Connect PSU 1 and PSU 2 with the DRR-20A module and  
Set output load condition for both supplies at 50% and measure  
measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure  
the output voltages.  
the voltages are within ±25mV.  
Step 2.  
Step 4.  
Adjust output voltages to the same level or within ±25mV  
difference.  
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.  
All parameters are specified at 25°C ambient unless otherwise indicated.

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.  
All parameters are specified at 25°C ambient unless otherwise indicated.
