All values in this document are typical values under the following conditions
unless otherwise noted: 230V AC 50 Hz input voltage, 24V 2.5 A output load,
25 °C (77 °F) ambient temperature, and after a 5 minutes run-in time.
Product Overview The 1606-XLB60EH is a DIN rail mountable single-phase input power supply,
which 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).

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.

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 2500 μF with 2.5 A
or 5000 μF with 1.25 A additional current load.
At heavy overloads (when output voltage falls below 14V), the power supply
delivers continuous output current for 25 ms. After this, the output is switched
off for approximately 145 ms before a new start attempt is automatically
performed. This cycle is repeated as long as the overload exists. If the overload
has been cleared, the device operates normally.

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 status indicator is also on during this time.
