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".
A value that is displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±15%) included. For
AC 230V
example, DC 12V describes a 12V battery 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.
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
50 Hz versus 60 Hz
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.
Product Overview
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.
The 1606-XLS480-UPS uninterruptible power supply
controller (DC-UPS) is used in addition with a 24V
power supply and batteries to bridge power failures
or voltage fluctuations. This configuration can help
prevent expensive downtimes, long restart cycles,
and loss of data.
A unique feature is the constant voltage in battery
mode, which will not change as the batteries
discharge. The buffer voltage in battery mode can be
set to four different output values. Another feature is
the utilization of two independent battery chargers
for the two 12V-batteries in series. This feature
makes matching batteries unnecessary and allows for precise battery
charging, testing, and optimized usage of the battery capacity to achieve the
longest battery service life.
The 1606-XLS480-UPS includes many battery diagnostic functions that deliver
a reliable operation of the entire system. Furthermore, a temperature that is
controlled charging extends the life of the batteries. It also includes a
selectable buffer time limiter and ready, buffering, and replace battery
contacts. For safety and maintenance, an inhibit input signal is included which
helps prevent a battery backup.100...240V wide-range input
