Terminology and
Abbreviations Term Definition
230V AC A figure with the unit (V AC) at the end is a momentary figure without any additional
tolerances included.
50 Hz vs. 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.
AC 230V A figure that is displayed with the AC or DC before the value represents a nominal
voltage with standard tolerances included. For example: DC 12V describes a 12V battery,
whether it is full (13.7V) or flat (10V)
Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.
PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol.

Basic Power Supply 5 A
Product Overview 1606-XLB Basic Power Supplies are
compact, industrial grade power supplies that
focus on the essential features needed in
industrial applications.
The housing is made of a high-grade,
reinforced molded material, which permits
the units to be used in ambient temperatures
up to 70 °C (158 °F).
This power supply features a wide input
voltage range, which makes it suitable for
global use.
The addition of a DC-OK signal makes the
power supply ideal for many industry
applications such as: process, automation,
and many other critical applications where
preventive function monitoring can help to
avoid long downtimes.
The 1606-XLB120E power supply offers these features:
• 100…120V/200…240V AC auto-select input
• Cost that is optimized without compromising the quality or reliability
• Small width of 39 mm (1.54 in.) takes up less space on the DIN rail
• Efficiency up to 92.3%
• Full power between -10…+55 °C (14…131 °F)
• DC-OK relay contact included
•1-yearwarranty

In case of an internal power supply anomaly, a redundant
circuit limits the maximum output voltage. In such a
case, the output shuts down and stays down until the
input voltage is turned off and on again for at least 1
minute or until the green status indicator went off.
