Basic Power Supply 10 A
Product Overview
1606-XLB Basic Power Supplies are
compact, industrial grade power supplies that
focus on the essential features needed in
industrial applications.
The mechanically robust housing is made of
a high-grade, reinforced molded material,
which permits the units to be used in
ambient temperatures up to 70 °C (158 °F).
This power supply features a wide input
voltage range, which makes it suitable for
global use.
The addition of a DC-OK signal makes the power supply ideal for many
industry applications such as: process, automation, and many other critical
applications where preventive function monitoring can help to avoid long
downtimes.
The 1606-XLB240E power supply offers these features:
• Wide input range, AC 100…240V
• Active PFC
• Cost optimized without compromising quality or reliability.
• Small width of only 49 mm (1.93 in.)
• Efficiency up to 95.2%
• Full power between -25…+55 °C (-13…+131 °F)
• DC-OK relay contact
• 1-year warranty

In case of an internal power supply
anomaly, a redundant circuit limits the
maximum output voltage. In such a case,
the output shuts down and stays down
until the input voltage is turned off and on
again for at least 1 minute or until the
green status indicator went off.

(1) The Lifetime expectancy that is 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 specified in operational hours and is calculated
according to the capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum
life of up to 15 years (131 400 h). Any number exceeding this value is a calculated theoretical lifetime that can be used to compare
devices.
(2) 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 figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of for example, 1 000 000 h means
that statistically one unit fails every 100 hours if 10 000 units are installed in the field. However, it cannot be determined if the
failed unit has been running for 50 000 h or only for 100 h.

Basic Power Supply 10 A
Peak Current Capability
Application Notes
The unit can deliver peak currents (up to several milliseconds) which are
higher than the specified short-term currents.
This helps to start current demanding loads. 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 capacitive load.
The peak current capability also delivers the safe operation of subsequent
circuit breakers of load circuits. The load branches are often individually
protected with circuit breakers or fuses. If there is a short or an overload in one
branch circuit, the fuse or circuit breaker need a certain amount of overcurrent
to open in a timely manner. This avoids voltage loss in adjacent circuits.
The extra current (peak current) is supplied by the power converter and the
built-in large sized output capacitors of the power supply. The capacitors get
discharged during such an event, which causes a voltage dip on the output. The
following two examples show typical voltage dips:

Basic Power Supply 10 A
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 malfunctioning 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 35V DC. The absorbing energy
can be calculated according to the built-in large sized output capacitor that is
specified in Output on page 10.
External Input Protection
The unit is tested and approved for branch circuits up to 30 A (UL) and 32 A
(IEC). 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 can 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 10A B-characteristic or 6A C-characteristic breaker should be used.
Parallel Use to Increase Output Power
Do not use the power supply in parallel to increase the output power.
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.
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 utilizing decoupling diodes that are included in the redundancy
module.
16
Rockwell Automation Publication 1606-RM056A-EN-P - December 2016
Basic Power Supply 10 A
Recommendations for building redundant power systems:
– Use the DC-OK signal contact to monitor the individual power
supply units.
– Use separate input fuses for each power supply.
– Use separate mains systems for each power supply whenever it is
possible.
– It is desirable to set the output voltages of all units to the same value
(± 100 mV) or leave it at the factory setting.
Series Operation
Power supplies of the 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 150V DC. Voltages with a
potential above 60V DC are not SELV any more and can be dangerous. Such
voltages must be installed with a protection against touching.
Earthing of the output is required when the sum of the output voltage is above
60V DC.
Avoid return voltage (for example, from a decelerating motor or battery) which
is applied to the output terminals.
Keep an installation clearance of 15 mm (0.59 in.) (left/right) between two
power supplies and avoid installing the power supplies on top of each other.
Pay attention that leakage current, EMI, inrush current, harmonics increase
when using multiple power supplies.

Inductive and Capacitive Loads
The unit is designed to supply any kind of loads, including capacitive and
inductive loads. If extreme large capacitors, such as EDLCs (electric double
layer capacitors or “UltraCaps”) with a capacitance larger than 2.0 F are
connected to the output, the unit might charge the capacitor in the
HiccupPLUS mode, see Output on page 10.
Charging of Batteries
Do not use the power supply to charge batteries.
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+10%.

Use in a Tightly Sealed Enclosure
When the power supply is installed in a tightly sealed enclosure, the
temperature inside the enclosure is higher than outside. In such situations, the
inside temperature defines 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
items are inside the box.

To meet the PELV requirements according to EN60204-1 § 6.4.1, we
recommend that either the + pole, the – pole or any other part of the output
circuit shall be connected to the protective earth system. This helps to avoid
situations in which a load starts unexpectedly or cannot be switched off when
unnoticed earth faults occur.
