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
.
