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 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 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
in instruction sheet with 13A B- or 10A 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 (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 (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 than100%, 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”. The power
supply does not shut down but goes in 2nd level regulation at 30-
32Vdc and continue to deliver the power. According to high output
voltage which will be operating > 100% of rated load (32V × rated
output current), if this condition persists, the power supply will
sense OTP (Over Temperature Protection) and will go under
hiccup mode. The power will return to normal operation once the
fault condition is removed.
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-40N (or 40A) 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.

The input voltage applied from Line to Neutral is below the maximum rated input. The input voltage shall be below 240Vac +10%.
Step 2.
The external protector is needed on N (Neutral) input line to secure a safety. N line does not have internal fuse protection. An appropriate
fuse or circuit breaker should be connected in series with N input line connection like the following.

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.
