Product Overview
The 1606-XLE units are high-end power supplies in a medium price range
without compromising quality, reliability, and performance. The XLE Series is
part of the Bulletin 1606 power supply family.
The 1606-XLE120E power supplies come with three connection terminal
options: screw, spring-clamp, or push-in terminals, which are optimized for
automated wiring.
The 1606-XLE120EC is equipped with conformal coated printed circuit boards
that are preferred for the use in harsh environments and the 1606-XLE120ED
features an enhanced DC input voltage range.
These units feature a small size, high efficiency, electronic inrush current
limitation, active power factor correction, and a wide operational temperature
range. The devices have a power reserve of 20% included, which can even be
used continuously at temperatures up to +45 °C (113 °F). Additionally, they can
deliver three times the nominal output current for 12 ms that helps to trip fuses
on faulty output branches.
High immunity to transients and power surges and low electromagnetic
emission, a DC OK signal contact for remote monitoring, and a large
international approval package for various applications.

Term Definition
PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol.
Earth, Ground This document uses the term ‘earth’ which is the same as the U.S. term ‘ground.’
AC 230V A figure 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 figure with the unit (V AC) at the end is a momentary figure without any additional
tolerancesincluded.
50 Hz vs. 60 Hz As long as not otherwise stated, AC 230V parameters are valid at 50 Hz mains frequency.

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.

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 extreme large capacitors, such as EDLCs (electric double
layer capacitors or ‘Ultra Caps’) with a capacitance > 0.3 F are connected to the
output, the unit can 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 can occur.

Max 35V 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 (when output voltage falls below 13V), the power supply delivers continuous output current for 1s. After this, the output is switched off for approx. 9s 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 will operate normally. See Figure 10

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 lamp is also on during this time
.

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 or 15 A for the 1606-XLE120EH. If the current is higher, use a
separate distribution terminal block as shown in Figure 23.
Lifetime Expectancy 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 manufacturer
specification. The manufacturer of the electrolytic capacitors only guarantees
a maximum life of up to 15 years (131,400 hr). Any number exceeding this value
is a calculated theoretical lifetime that can be used to compare devices.
Mean Time Between Failure
(MTBF)
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.
The MTBF figure is a statistical representation of the likelihood of a device to
fail. An MTBF figure of, for example, 1,000,000 hr means that statistically one
unit will fail 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 50,000hr or
only for 100 hr.
For these types of units, the MTTF (Mean Time To Failure) value is the same
value as the MTBF value.

Safety and Protection
Features
Dielectric Strength The output voltage is floating and has no ohmic connection to the ground. The
output is insulated to the input by a double or reinforced insulation.
Type and routine tests are conducted by the manufacturer. Field tests can be
conducted in the field using the appropriate test equipment that 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 table below.
We recommend that either the + pole or the – pole is to 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.
Isolation resistance
Min 500 M Ohm At delivered condition between input and output, which is measured with 500V DC
Min 500 M Ohm At delivered condition between input and PE, measured with 500V DC
Min 500 M Ohm At delivered condition between output and PE, measured with 500V DC
Min 500 M Ohm At delivered condition between output and DC OK contacts, which are measured with 500V DC
PE resistance Max 0.1 Ohm Resistance between PE terminal and the housing in the area of the DIN rail mounting bracket
Output overvoltage protection
Typ 30.5V DC
Max 32.0V DC
In case of an internal anomaly, a redundant circuit limits the maximum output voltage. The output shuts down and performs three restart
attempts. If the failure continues, the output shuts down. Cycle input power to reset.
Class of protection I According to IEC 61140 — A PE (Protective Earth) connection is required
Degree of protection IP 20 According to EN/IEC 60529
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, which can happen, for example, 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.
