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
a high-grade, reinforced molded material,
which permits surrounding temperatures
up to 70 °C (158 °F).
