DC/DC Converter - 48V/48V, 5 A, 240 W Reference Manual
Terminology and
Abbreviations
All values in this document are typical values under the following conditions
unless otherwise noted:

Product Overview
The 1606-XLDF240F is a DIN rail mountable DC/DC
converter that provides a floating, stabilized, and
galvanically separated SELV/PELV output voltage.
The converter offers high efficiency, a small size, and
a wide operational temperature range. It has a power
reserve of 20% included, which can be used
continuously at temperatures up to 45 °C (113 °F).
High immunity to transients and power surges, low
electromagnetic emission, and a large international
approval package for various applications makes this
unit suitable for nearly every situation.
Product features:
•
48V DC input
•
Isolated 48V DC output
•
Efficiency up to 95.1%
•
Width only 42 mm (1.65 in.)
•
20% output power reserves
•
Full power between -25…+60 °C (-13…+140 °F)
•
Soft start function
•
Minimal inrush current surge
•
Reverse input polarity protection

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”.
DC 48V
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).
48V DC
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.
Max
Indicates a maximum value.
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.
