package.
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”.
AC 230V 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 disregarding whether it is full (13.7V) or flat (10V).
230V AC A value with the unit (V AC) at the end is a momentary value without any additional
tolerances included.
50 Hz versus 60 Hz As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50 Hz
mains frequency. AC 120V parameters are valid for 60 Hz mains frequency.
nom Indicates a nominal value.
typ Indicates a typical value.
— (alone in table cell) A dash alone in a table cell indicates that there is no information to be included in that
cell.
Figure 1 - Input Voltage Range The 1606-XLE120F is a cost optimized power
supply that does not compromise on quality,
reliability, or performance. It covers a DC input
range up to 150V DC.
The power supply has a small size, high efficiency,
electronic inrush current limitation, active power
factor correction, and a wide operational
temperature range. The power supply has a power
reserve of 20% included, which can even be used
continuously at temperatures up to 45 °C (113 °F).
It can deliver three times the nominal output
current for 12 ms, which helps to trip fuses on
faulty output branches.

DC Input The device is suitable to be supplied from a DC input voltage. Use a battery or a
similar DC source. A supply from the intermediate DC bus of a frequency
converter is not recommended and can cause a malfunction or damage the
unit. Connect +pole to L, –pole to N and the PE terminal to an earth wire or to
the machine ground.
Figure 6 - Wiring for DC Input
Input Inrush Current An active inrush limitation circuit (NTCs, which are bypassed by a relay
contact) limits the input inrush current after turn-on of the input voltage. The
charging current into EMI suppression capacitors is disregarded in the first
microseconds after switch-on.

Output The output provides a SELV/PELV rated voltage, which is galvanically isolated
from the input voltage.
The output is designed to supply any kind of loads, including capacitive and
inductive loads. If large capacitors, such as EDLCs (electric double layer
capacitors or “UltraCaps”) with a capacitance > 0.1 F, are connected to the
output, the unit might charge the capacitor in an intermittent mode.
The output is electronically protected against overload, no-load, and short-
circuits. If there is a protection event, audible noise may occur.

current that helps to trip fuses on faulty output branches. The output voltage stays above 40V.

Back-feeding loads Max 63V The unit 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 absorbing energy can be
calculated according to the built-in large sized output capacitor.
(1) This current is also available for temperatures up to 70 °C (158 °F) with a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
(2) At heavy overloads, the power supply delivers continuous output current for 1 s. After this, the output is switched off for approx 9 s before a new start attempt
is automatically performed. This cycle is repeated as long as the overload exists. If the overload is cleared, the device operates normally. See Figure 11.

Hold-up Time The hold-up time is the time during which a power supply’s output voltage
remains within specification following the loss of input power. The hold-up
time is output load dependent. At no load, the hold-up time can be up to
several seconds. The green DC OK status indicator is also on during this time.

Connection Terminals The terminals are IP20 fingersafe constructed and suitable for field- and
factory wiring.
Daisy Chaining
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 25 A. If the current is higher, use a separate distribution terminal block
as shown in Figure 22.

Lifetime Expectancy The Lifetime expectancy values that are shown in the table indicate the
minimum operating hours (service life) and are determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is
specified in operational hours and is calculated according to the specification
of the capacitor manufacturer. The manufacturer of the electrolytic capacitors
only states 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 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 hr
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 hr or only for 100 hr.

Safety and Protection
Features
Dielectric Strength The output voltage is floating and has no ohmic connection to the ground.
Either 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 input-terminals
together and all output poles before conducting the test. When testing, set the
cutoff current settings to the value in the following table.
We recommend 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.
Attributes Values Notes

Over-temperature protection — Included
Output shutdown with automatic restart. Temperature sensors are installed on critical components
inside the unit and turn off the unit in safety critical situations. Examples of these situations include
when ambient temperature is too high, ventilation is obstructed, or the derating requirements are
not followed. There is no correlation between the operating temperature and turn-off temperature
since this is dependent on input voltage, load, and installation methods.
