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 3.8 A output load,
25 °C (77 °F) ambient temperature, and after a 5 minutes run-in time.
Product Overview
The 1606-XLB90E is part of a series of compact industrial grade DIN rail power
supplies that focus on the essential features needed in present day industrial
applications. The excellent cost/performance ratio does not compromise
quality or reliability.
The mechanically robust housing is made of a high-grade, reinforced molded
material, which permits the units to be used in surrounding temperatures up
to 70 °C (158 °F).
The 1606-XLB90E is equipped with large screw terminals for easy wiring.
Product features:
•
100…240V wide-range input
•
Cost-optimized without compromising quality or reliability
•
Width only 36 mm (1.42 in.)
•
Efficiency up to 93.8%
•
Low no-load power losses
•
Full power between -10…+60 °C (14…140 °F)
•
Large screw terminals

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.
