Terms Descriptions
PE The abbreviation for Protective Earth. PE has the same meaning as the symbol.
The symbol for Protective Earth.
Earth, Ground This document uses the term “earth”, which is the same as the U.S. term “ground”.
DC 300V A value that is displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±15%) included. For example, DC 12V
describes a 12V battery, no matter if it is full (13.7V) or flat (10V).
300V DC A value with the unit (V DC) at the end is a momentary value without any additional
tolerances included.
Nom Indicates a nominal value.
Typ Indicates a typical value.
—A dash alone in a table cell indicates that there is no information to be included in that
cell.
Figure 1 - 1606-XLE480FP-D The 1606-XLE480FP-D is a cost-
optimized power supply unit and
DC/DC converter. Features of these
units include a wide DC-input range,
electronic inrush current limitation, and
a wide operational temperature range.
Power reserves of 20% can be used
continuously at temperature up to
45 °C (113 °F). Additionally, the
1606-XLE480FP-D DC/DC converter
delivers about 4 times the nominal
output current for 15 ms, which can trip
fuses on faulty output branches.
The 1606-XLE480FP-D DC/DC converter
has a high immunity to transients and
power surges, and has low
electromagnetic emissions and a DC-OK
relay contact.
The 1606-XLE480FP-D DC/DC converter
features a large international approval
package for various applications.

AC Input Do not operate this DC/DC converter with AC-input voltage. Use the
1606-XLE480EP unit instead.
DC Input Use a battery or a similar DC source. We do not recommend using a supply
from the intermediate DC-bus of a frequency converter as it can cause a
malfunction or damage the unit.

(3) At heavy overloads (when output voltage falls below 13V), the DC/DC converter delivers continuous output current for 2 s.
After which, the output switches off for approximately 18 s before automatically attempting a new start. The cycle repeats as
long as the overload exists. The device operates normally once the overload is cleared. See Figure 8 on page 7.

Hold-up Time A diode to the input voltage isolates the internal capacitor that supplies the
energy for the hold-up time. A short on the input line does not discharge the
internal hold-up capacitor.
DC-OK Relay Contact This feature monitors the output voltage that the DC/DC converter produces.
It is independent of any back-fed voltage from a unit that is connected in
parallel to the DC/DC converter output.

Parallel Use/Single Use selector
Set the jumper to Parallel Use when the DC/DC converters are
connected in parallel to increase the output power. To achieve a
sharing of the load current between the individual units, the Parallel
Use regulates the output voltage in such a manner that the voltage at
no load is approximately 4% higher than at nominal load. See Parallel
Use to Increase Output Power on page 20. A missing jumper is equal to

Calculated lifetime expectancy (1)
(1) The minimum operating hours (service life). The lifetime expectancy of the built-in electrolytic
capacitors determines the service life. Lifetime expectancy is specified in operational hours and is
calculated according to the manufacturer specification of the capacitor. The manufacturer of the
electrolytic capacitors lists a maximum life of up to 15 years (131,400 hr). Any number that exceeds this
value is a calculated theoretical lifetime, which can be used to compare devices.

Mean Time Between Failure
(MTBF)
MTBF is calculated according to statistical device failures, and indicates the
reliability of a device. It is the statistical representation of the likelihood of a
unit to fail; it does not necessarily represent the life of a product. An MTBF
value of, for example, 1,000,000 hr means that statistically one unit fails every
100 hours if 10,000 units are installed in the field. However, the running time
of individual failed units cannot be determined.
Electromagnetic

The DC/DC converter is suitable for applications in an industrial environment
and in a residential, commercial, and light industry environment without any
restrictions.
The DC/DC converter has two converters with two different switching
frequencies, which are included.

manufacturer conducts type and factory tests. Field tests can be conducted
with the appropriate test equipment, which applies the voltage with a slow

all output poles before conducting the test. When testing, set the cutoff

The 1606-XLA-S63 side-mounting bracket is used to mount units sideways,

the black plastic slider of the unit to mount the steel brackets.
For sideway DIN rail mounting, mount the aluminum brackets and the black
plastic slider onto the steel bracket.
1606-XLSRED40HF Redundancy Module
The 1606-XLSRED40HF redundancy module is equipped with two input
channels, which use mosfet technology to decouple individually. The use of
mosfets instead of diodes reduces the heat generation and the voltage drop
between input and output. The module does not require an additional
auxiliary voltage and is self-powered, even if there is a short circuit across the
output.
Due to the low-power losses, the unit is slender and requires a 46 mm (1.81 in.)
wide DIN rail.

Peak Current Capability The DC/DC converter can deliver peak currents (up to several milliseconds)
which are higher than the specified short-term currents.
Peak current capability helps to start current-demanding loads. Solenoids,
contactors, and pneumatic modules often have a steady state coil and a pickup
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 Power Boost). The same situation applies when starting a
capacitive load.
The peak current capability also achieves 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 needs a certain amount of
overcurrent to open in a timely manner. This safety 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 DC/DC converter. The capacitors
get discharged during such an event, which causes a voltage dip on the output.
Figure 30 and Figure 31 show typical voltage dips.
Back-feeding Loads Loads such as decelerating motors and inductors can feed voltage back to the
DC/DC converter. This feature is also called return voltage immunity, or
resistance against Back Electromagnetic Force (Back EMF).
This DC/DC converter is resistant and does not show malfunctions when a
load feeds back voltage to the unit, regardless of whether the unit is on or off.
The maximum allowed feed back voltage is 63V DC. The absorbing energy can
be calculated according to the built-in large-sized output capacitor, which is
specified in Output on page 6.
