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 22-1.
Peak current voltage dips typ. from 24V to 16V at 5A for 50ms, resistive load

*) 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 manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years
(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.
**) 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 can not be determined if the failed unit
has been running for 50 000h or only for 100h.

All parameters are specified at 24V, 2.5A, 230Vac input, 25°C ambient and after a 5 minutes run-in time, unless noted otherwise.

21. Accessory
21.3. 1606-XLSBUFFER24 Module
This buffer unit is a supplementary device for DC 24V power supplies. It delivers power to bridge typical mains failures
or extends the hold-up time after turn-off of the AC power. In times when the
power supply provides sufcient voltages, the buffer module stores energy in
integrated electrolytic capacitors. In case of mains voltage fault, this energy is
released again in a regulated process. One buffer module can deliver 20A which
can also be used to support peak current demands.
The buffer unit does not require any control wiring. It can be added in parallel to
the load circuit at any given point. Buffer
units can be added in parallel to increase
the output ampacity or the hold-up time.

22. Application Notes
22.1. 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. The same situation applies when starting a motor or switching on a capacitive load.
In many cases, the peak current capability also ensures a safe operation of subsequent circuit breakers. Branch circuits
are often protected with circuit breakers or fuses. In case of a short or an overload in a branch circuit, the fuse needs a
certain amount of over-current to trip or to blow.
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.
Both the examples below show typical voltage dips:

current for 50ms, typ.

current for 5ms, typ.

Output voltage dips from 24V to 16V. Peak load 12.5A (resistive load) for 5ms Output voltage dips from 24V to 10.5V.
22.2. 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).
This power supply is resistant and does not show malfunction when a load feeds back voltage to the power supply.
It does not matter whether the power supply is on or off.
The maximum allowed feed-back-voltage is 35Vdc. The absorbing energy can be calculated according to the built-in
large sized output capacitor which is specied in section 5.

All parameters are specified at 24V, 2.5A, 230Vac input, 25°C ambient and after a 5 minutes run-in time, unless noted otherwise.
Rockwell Automation Publication 1606-RM007A-EN-P - February 2014 19
Bulletin 1606 Switched Mode Power Supplies
22.3. Charging Batteries
The power supply can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series.)
Instructions for charging batteries (oat charging):
a) Ensure that the ambient temperature of the power supply is below 45°C
b) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge
voltage.
End-of-charge voltage 27.8V 27.5V 27.15V 26.8V
Battery temperature 10°C 20°C 30°C 40°C
c) Use a 4A circuit breaker (or blocking diode) between the power supply and the battery.
d) Ensure that the output current of the power supply is below the allowed charging current of the battery.
e) Use only matched batteries when putting 12V types in series.
f) The return current to the power supply (battery discharge current) is typical 7.3mA when the power supply is
switched off (except when using a blocking diode).
22.4. 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. Local regulations may apply
If an external fuse is necessary or used, minimum requirements need to be considered to avoid nuisance tripping of
the circuit breaker. A minimum value of 10A B- or 6A C-Characteristic breaker should be used.

1606-XLP60EQ 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-XLP60EQ can also be paralleled with other power supplies
from the XLP family with 24V output voltage. The output voltages of all
power supplies shall be adjusted to the same value (±100mV).
A fuse or diode on the output of each unit is required only if more than three units are connected in parallel. If a fuse
(or circuit breaker) is used, 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).
Be aware that leakage current, EMI, inrush current and harmonics will increase when using multiple power supplies in
parallel.
in some countries.

All parameters are specified at 24V, 2.5A, 230Vac input, 25°C ambient and after a 5 minutes run-in time, unless noted otherwise.

Bulletin 1606 Switched Mode Power Supplies
22.6. 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 2.5A are paralleled to build a 10A 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 defect unit becomes a load for the other power supplies and the output voltage can not be
maintained any more. This can only be avoided by using decoupling diodes which are included in the redundancy
module 1606-XLPRED.

Recommendations for building redundant power systems:
a) Use separate input fuses for each power supply.
b) Use separate mains systems for each power supply whenever possible.
c) Monitor the individual power supply units.
d) 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.
e) It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.
22.7. Daisy Chaining of Outputs
Daisy chaining (jumping from one power supply output to the next) is allowed as long as the average output current
through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal block.
