Peak current capability (up to several milliseconds)

The power supply can deliver a peak current which is higher than the specied short term current. This helps to start
current demanding loads or to safely operate subsequent circuit breakers.

The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will be
discharged and causes a voltage dip on the output. Detailed curves can be found in section 20.1.

*) The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime

expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specied in operational hours and is calculated according to the
capacitor’s manufacturer specication. The prediction model allows only a calculation of up to 15 years from date of shipment.

**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a

device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.

The MTBF gure is a statistical representation of the likelihood of a device to fail. A MTBF gure of e.g. 1 000 000h means that

statistically one unit will fail every 100 hours if 10 000 units are installed in the eld. However, it cannot be determined if the failed unit
has been running for 50 000h or only for 100h.

20. Application Notes

20.1. Peak Current Capability

Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current
demand of the pick-up coil is several times higher than the steady-state current and usually exceeds the nominal
output current (including the PowerBoost) The same situation applies, when starting a capacitive load.

Branch circuits are often protected with circuit breakers or fuses. In case of a short or an overload in the branch circuit,
the fuse needs a certain amount of over-current to trip or to blow. The peak current capability ensures the safe
operation of subsequent circuit breakers.

Assuming the input voltage is turned on before such an event, the built-in large sized output capacitors inside the
power supply can deliver extra current. Discharging this capacitor causes a voltage dip on the output. The following
two examples show typical voltage dips:

Fig. 20-1 Peak loading with 2x the nominal

current for 50ms, typ.

Fig. 20-2 Peak loading with 5x the nominal

current for 5ms, typ.

Peak load 6A (resistive load) for 50ms
Output voltage dips from 5.1V to 2.4V.

Peak load 15A (resistive load) for 5ms
Output voltage dips from 5.1V to 0.8V.

20.2. Back-feeding Loads

Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called
return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).

The maximum allowed feed back voltage is 6.3Vdc. The absorbing energy can be calculated according to the built-in
large sized output capacitor which is specied in section 6.

This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply.
It does not matter, whether the power supply is on or off. However, please note that the output voltage can dip to
zero for approximately 200ms if the back-feed voltage is removed.

All parameters are specified at 5V, 3A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.

Rockwell Automation Publication 1606-RM019A-EN-P — March 2014 17

Bulletin 1606 Switched Mode Power Supplies

20.3. External Input Protection

The unit is tested and approved for branch circuits up to 20A. An external protection is only required, if the supplying
branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local
regulations might apply.

If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of
the circuit breaker. A minimum value of 6A B- or 3A C-Characteristic breaker should be used.

20.4. Parallel Use to Increase Output Power

1606-XLP15A power supplies can be paralleled to increase the output power.
This power supply does not include the capacity to balance the load current
between the power supplies. Usually the power supply with the higher
adjusted output voltage draws current until it goes into current limitation. This
causes no harm to the power supply as long as the ambient temperature stays
below 45°C. The 1606-XLP15A can also be paralleled with other XLP power supplies
with 5V output voltage. The output voltages of all power supplies must be
adjusted to the same value (±100mV).
A fuse or diode on the output of each unit is required only if you connect more than three units in parallel. If you use
a fuse or circuit breaker, choose one with approximately 150% of the rated output current of one power supply.
Keep an installation clearance of 15mm (left / right) between two power supplies and avoid installing the power
supplies on top of each other. Do not use power supplies in parallel in mounting orientations other than the standard
mounting orientation (input terminals on the bottom and output terminals on top of the unit). Please note that leakage
current, EMI, inrush current and harmonics will increase when using multiple power supplies.

Bulletin 1606 Switched Mode Power Supplies

20.5. Parallel Use for Redundancy

Power supplies can be paralleled for redundancy to gain higher system availability. Redundant systems require a
certain amount of extra power to support the load in case one power supply unit fails. The simplest way is to put two
power supplies in parallel. This is called a 1+1 redundancy. In case one power supply unit fails, the other one is
automatically able to support the load current without any interruption. Redundant systems for a higher power
demand are usually built in a N+1 method. E.g. ve power supplies, each rated for 3A are paralleled to build a 12A
redundant system.

Please note: This simple way to build a redundant system does not cover failures such as an internal short circuit in
the secondary side of the power supply. In such a case, the failing unit becomes a load for the other power supplies
and the output voltage can no longer be maintained. This can only be avoided by using decoupling diodes
which are included in the decoupling module 1606-XLPRED.

Recommendations for building redundant power systems:
a) Use separate input fuses for each power supply.
b) Monitor the individual power supply units.
c) 1+1 Redundancy is allowed up to an ambient temperature of 60°C

N+1 Redundancy is allowed up to an ambient temperature of 45°C

d) It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

20.6. Series Operation

Power supplies of the exact same type can be connected in series for higher
output voltages. It is possible to connect as many units in series as needed,
providing the sum of the output voltage does not exceed 150Vdc. Voltages
with a potential above 60Vdc are not SELV any more and can be dangerous.
Such voltages must be installed with a protection against touching. Grounding
the output is required when the sum of the output voltage is above 60Vdc.
Avoid return voltage (e.g. from a decelerating motor or battery) which is
applied to the output terminals. Keep an installation clearance of 15mm (left /
right) between two power supplies and avoid installing the power supplies on
top of each other. Do not use power supplies in series in mounting
orientations other than the standard mounting orientation (input terminals on the bottom and output terminals on
top of the unit). Please note that leakage current, EMI, inrush current and harmonics will increase when using multiple
power supplies.

20.7. Inductive and Capacitive Loads

The unit is designed to supply unlimited inductive loads.
The max. capacitive load depend on the steady state output current. At 3A output current, the output capacity should

not be larger than 10 000μF and at 0.3A output current not larger than 25 000μF. In case of larger capacitors, the unit
can show start-up attempts or start-up problems.

All parameters are specified at 5V, 3A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.

20.8. Operation on Two Phases

The power supply can also be used on two phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying
voltage is below 240V
input. The N input is not protected internally; in this case it is connected
to a hot wire. Appropriate fuses or circuit breakers are specied in section

20.9. Use Without PE on the Input

From a safety standpoint, the unit is internally designed according to the requirements for Protection Class 1 and 2.
Contact Rockwell Automation if you do not use the PE terminal. A different marking of the front foil is then required.

Grounding of the input is benecial for a high EMI immunity: Symmetrical spikes or fast transients on the input side
can be conducted directly to earth by the built-in lter capacitors. The magnitude of such spikes or fast transients on
the output side caused by the input is much smaller compared to not connecting this terminal to the ground.

20.10. Use in a Tightly Sealed Enclosure

When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher
than outside. In such situations, the inside temperature denes the ambient temperature for the power supply.

The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The power supply is placed in the middle of the box; no other heat producing item is inside the box.
Enclosure: Rittal Type IP66 Box PK 9510 100, plastic, 130x130x75mm

Input: 230Vac

Case A:
Load: 5V, 3A; load is placed outside the box.
Temperature inside the box: 38.2°C (in the middle of the right side of the power supply with a distance of 1cm)
Temperature outside the box: 26.0°C
Temperature rise: 12.2K

Case B:
Load: 5V, 2.4A; (=80%) load is placed outside the box.
Temperature inside the box: 35.3°C (in the middle of the right side of the power supply with a distance of 1cm)
Temperature outside the box: 25.6°C
Temperature rise: 9.7K

All parameters are specified at 5V, 3A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.

20.11. Mounting Operations

Mounting orientations other than input terminals on the bottom and output on the top require a reduction in
continuous output power or a limitation in the max. allowed ambient temperature. The amount of reduction
inuences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous
operation can be found below:

Curve A1 Recommended output current.
Curve A2 Max allowed output current (results in approximately half the lifetime expectancy of A1).
