Terminology and
Abbreviations
All values in this document are typical values under the following conditions
unless otherwise noted: 230V AC 50 Hz input voltage, 24V 2.5 A output load,
25 °C (77 °F) ambient temperature, and after a 5 minutes run-in time.
Product Overview The 1606-XLB36EH is a DIN rail mountable single-
phase input power supply, which provides a floating,
stabilized, and galvanically separated SELV/PELV/
ES1 output voltage.
The output fulfills the requirements for a limited
power source according to NEC CLASS 2.
The device is equipped with push-in terminals,
which are optimized for automated wiring. The
mechanically robust housing is made of a high-
grade, reinforced molded material, which permits
surrounding temperatures up to 70 °C (158 °F).
The unit is designed as “Class of Protection” II unit and fulfills the safety and
electromagnetic compatibility (EMC) requirements without an input PE
connection. This saves wiring costs.
The 1606-XLB36EH is part of a series of compact, industrial grade DIN rail
power supplies. This series focuses on the essential features that are needed in
present day industrial applications. The excellent cost/performance ratio does
not compromise quality or reliability.

Input Inrush Current An NTC limits the input inrush current after turn-on of the input voltage. The
inrush current is input voltage and ambient temperature dependent. The
output load has no impact on the inrush current value.
The charging current into EMI suppression capacitors is disregarded in the
first microseconds after switch-on.

Output The output provides a SELV/PELV/ES1 rated voltage, which is galvanically
isolated from the input voltage.
The output is electronically protected against no-load, overload, and short
circuit. If there is a protection event, audible noise may occur.
The output is designed to supply any kind of loads, including inductive and
capacitive loads. Capacitive loads should not be larger than 5400 μF with 1.5 A
or 7300 μF with 0.75 A additional current load.
At heavy overloads (when output voltage falls below 14V), the power supply
delivers continuous output current for 60 ms. After this, the output is switched
off for approximately 400 ms before a new start attempt is automatically
performed. This cycle is repeated as long as the overload exists. If the overload
has been cleared, the device operates normally.

Lifetime Expectancy The lifetime expectancies that are shown in the table indicate the minimum
operating hours (service life). The lifetime expectancy of the built-in
electrolytic capacitors determines the lifetime expectancy of the power supply.
Lifetime expectancy is specified in operational hours and is calculated
according to the manufacturer specification of the capacitor.
The manufacturer of the electrolytic capacitors only states a maximum life of
up to 15 years (131,400 h). Any number that exceeds this value is a calculated
theoretical lifetime, which can be used to compare devices.
Mean Time between Failure Mean time between failure (MTBF) 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. An MTBF value 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. For these types of units, the Mean Time To Failure (MTTF) value is
the same as the MTBF value.
Electromagnetic
Compatibility
The electromagnetic compatibility (EMC) behavior of the device is designed
for applications in industrial, residential, commercial, and light industrial
environments. The device complies with EN 61000-6-1, EN 61000-6-2,
EN 61000-6-3, EN 61000-6-4, EN 61000-3-2, and EN 61000-3-3.
The device complies with FCC Part 15 rules. Operation is subjected to following
two conditions: (1) this device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may
cause undesired operation.

Safety and Protection
Features
Dielectric Strength The output voltage is floating and has no ohmic connection to the ground.
A double or reinforced insulation insulates the output to the input.
The manufacturer conducts type and routine tests. Field tests may be
conducted in the field using the appropriate test equipment, which applies the
voltage with a slow ramp (2 s up and 2 s down). Connect all phase-terminals
together and all output poles before conducting the test. When testing, set the
cutoff current settings to the value in the following table.
It is recommended that either the + pole or the – pole 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.

Series Operation Devices 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 must be installed with a protection against touching.
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.
Leakage current, EMI, inrush current, and harmonics increase when using
multiple devices.
Figure 24 - Series Operation
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%.
Confirm that the wire, which is connected to the N-terminal, is appropriately
fused.

Use In a Tightly Sealed
Enclosure
When the device 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 device.
In the following test setup, the device is placed in the middle of the box, no
other heat-producing items are inside the box. The load is placed outside the
box.
The temperature sensor inside the box is placed in the middle of the right side
of the power supply with a distance of 1 cm (0.39 in.). The following
measurement results can be used as a reference to estimate the temperature
rise inside the enclosure.
Prohibited and Unsupported
Applications
This section covers applications in which the 1606-XLB36EH power supply is
either prohibited or not recommended.
DC Input
Do not operate this power supply with DC input voltage.
Charging of Batteries
Do not use the power supply for the charging of batteries.
Parallel Use to Increase Output Power
