Terminology and
Abbreviations
All values in this document are typical values under the following conditions
unless otherwise noted: 230V AC 50 Hz input voltage, 12V 5 A output load, 25 °C
(77 °F) ambient temperature, and after a 5 minutes run-in time.
Product Overview
The unit is designed as a 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-XLB60BH is part of a series of compact, industrial grade DIN rail
power supplies that focuses on the essential features that are needed in
present day industrial applications. The excellent cost/performance ratio does
not compromise quality or reliability.
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 - 1606-XLB60BH Power Supply The 1606-XLB60BH is a DIN rail mountable
single-phase-input power supply. It
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

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 2200 μF with 5 A or
8000 μF with 2.5 A additional current load.
At heavy overloads (when output voltage falls below 8V), the device delivers
continuous output current for 20 ms. After the 20 ms have passed, the output
is switched off for 170 ms before a new start attempt is automatically
performed. This cycle is repeated as long as the overload exists.

Hold-up Time The hold-up time is the time during which the output voltage of a power supply
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.
