1. Description

This uninterruptible power supply (UPS) controller
1606-XLS240-UPSE is an addition to standard 24V
power supplies to bridge power failures or
emergency systems which must be kept fully in
operation for e.g. 72 hours.

The DC-UPS includes an internal temperature sensor
and a professional battery management system
which charges and monitors the battery to achieve
the longest battery service life as well as many
diagnostic functions that ensure a reliable operation
of the entire system.

A unique feature of the 1606-XLS240-UPSE is that only
one 12V battery is required to buer the 24V
output. This makes matching batteries unnecessary
and allows a precise battery charging and testing.

Electric output current limitation

The DC-UPS is equipped with an electronic output
current limitation. This current limitation works
in a switching mode which reduces the power
losses and heat generation to a minimum. As a
result, the output voltage drops since there is not
enough current to support the load. A positive
eect of the current limitation in switching mode
is that the input current goes down despite an
increase in the output current resulting in less
stress for the supplying source.

*) The charging time depends on the duration and load current of the last buer event. The numbers in the table represent a

fully discharged battery.

**) The current between the battery and the DC-UPS is more than twice the output current. This is caused by boosting the 12V

battery voltage to a 24V level. This high current requires large wire gauges and short cable length for the longest possible
buer time. The higher the resistance of the connection between the battery and the DC-UPS, the lower the voltage on the
battery terminals which increases the discharging current. See also section 26 for more installation instructions.

***) To ensure longest battery lifetime, the DC-UPS has a battery deep discharge protection feature included. The DC-UPS stops

buering when the voltage on the battery terminals of the DC-UPS falls below a certain value. The yellow LED will show
“buer time expired” for a period of 15 minutes after the unit stopped buering.

The battery capacity is usually specied in amp-hours (Ah) for a 20h discharging event. The battery discharge is non­linear (due to the battery chemistry). The higher the discharging current, the lower the appropriate battery capacity.
The magnitude of the reduction depends on the discharging current as well as on the type of battery. High current
battery types can have up to 50% longer buer times compared to regular batteries when batteries are discharged
in less than one hour.

High discharging currents do not necessarily mean high power losses as the appropriate battery capacity is reduced
with such currents. When the battery begins to recharge after a discharging event, the process is completed much
faster since only the energy removed from the battery needs to be “relled.”

For this reason, the buer time cannot be calculated using the Ah capacity value. The equation “I x t” = capacity in
Ah generally leads to incorrect results when the discharging current is higher than C20 (discharging current for 20h).

12. Check Wiring and Battery Quality Tests

The DC-UPS is equipped with an automatic “Check Wiring” and “Battery Quality” test.

“Check Wiring” test:

Under normal circumstances, an incorrect or bad connection from the battery to the DC-UPS or a missing (or blown)
battery fuse would not be recognized by the UPS when operating in normal mode. Only when backup is required
would the unit be unable to buer. Therefore, a “Check Wiring” test is included in the DC-UPS. This connection is
tested every 10 seconds by loading the battery and analyzing the response from the battery. If the resistance is too
high, or the battery voltage is not in range, the unit displays “Check Wiring” along with the red LED. At the same time,
the green “Ready” LED will turn o.

“Battery Quality” or “State of Health” (SoH) test:

The battery has a limited service life and needs to be replaced at xed intervals determined by the specied service
life (acc. to the Eurobat guideline), based on the surrounding temperature and the number of charging and
discharging cycles. If the battery is used longer than the specied service life, its capacity will degrade. Section 27-1
contains additional information on the topic. The battery quality test cannot identify a gradual loss in capacity.
However, it is able to detect a battery failure within the specied service life of the battery. Therefore a battery quality
test in included in the DC-UPS.
A battery problem is indicated by the yellow LED (replace battery pattern) and the relay contact “Replace Battery.”
Please note that it can take up to 170 hours (with the largest battery size) until a battery problem is reported. This
should avoid nuisance error messages as any urgent battery problems will be reported by the “Check Wiring” test and
create a warning signal.
When “Replace Battery” is indicated, we recommend replacing the battery as soon as possible.

13. End-of-Charge Voltage

The end-of-charge voltage depends on the temperature of the battery. An excessively high end-of-charge voltage may
damage the battery and shorten its lifetime. Therefore the DC-UPS includes an internal temperature sensor, which
regulates the end-of-charge voltage depending on the battery temperature. To achieve the longest lifetime,
the battery should be placed at the coldest location.

The temperature dierence between the DC-UPS and the battery requires a correction of the end-of-charge voltage.
This can be done with the selector on the front side of the unit. See section 15 for details.

14. Relay Contacts and Inhibit Input

The DC-UPS is equipped with relay contacts and signal inputs for remote monitoring and controlling of the unit.

Relay contacts:

Ready:

Contact is closed when battery is charged more than 85%, no wiring failure is recognized, input
voltage is sucient and inhibit signal is not active.

Buering: Contact is closed when unit is buering.
Replace Battery: Contact is closed when the unit is powered from the input and the battery quality test (SOH test)

reports a negative result.

Relay contact ratings max 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A resistive load
min 1mA at 5Vdc min.
Isolation voltage max 500Vac, signal port to power port

Signal input:

Inhibit: The inhibit input disables buering. In normal mode, a static signal is

required. In buer mode, a pulse with a minimum length of 250ms is
required to stop buering. The inhibit is stored and can be reset by
cycling the input voltage. See also section 27.3 for application hints.

The battery should be installed according to EN50272-2, which includes sucient ventilation. Batteries store energy and
must be protected against energy hazards. Use a 30A battery fuse type ATO® 257 30 (Littelfuse) or similar in the battery path.
The battery fuse protects the wires between the battery and the DC-UPS. It also allows the disconnection of the battery from
the DC-UPS which we recommend when working on the battery or DC-UPS. Disconnect battery fuse before connecting the
battery. Please note: Excessively long or short wires between the DC-UPS and battery may shorten the buer time or result
in a malfunction of the DC-UPS. Do not use wires smaller than 2.5mm² (or 12AWG) and no longer than 2x1.5m (cord length

1.5m). Avoid voltage drops on this connection.

27. Application Notes

27.1. Battery Replacement Intervals

Batteries have a limited lifetime. They degrade slowly beginning from the production and need to be replaced
periodically, The design life gures can be found in the indidividual battery datasheets and are usually specied according
to the Eurobat guideline or according to the manufacturer’s specications.

The design life is the estimated life based on laboratory condition, and is quoted at 20°C using the manufacturer’s
recommended oat voltage condition. According to the Eurobat guideline, design lives have been structured into the
following distinct groups:

3 - 5 years:

This group of batteries is very popular in stand-by applications and in small emergency equipment.

This represents a 4 years design life with a production tolerance of ±1 year.

6 - 9 years:

This group of batteries is generally used when an improved life is required.

This represents a 7.5 years design life with a production tolerance of ±1.5 years.

10 - 12 years:

This group of batteries is used in applications for which longest life and highest safety level are

required. This represents a 11 years design life with a production tolerance of ±1 year.

A battery failure within the specied design life of the battery usually results in complete loss of battery
function (broken cell, faulty connection, …) and will be detected and reported by the periodical battery tests
included in the 1606-XLS240-UPSE DC-UPS control unit.

If the operational parameters dier from those specied for the design life, earlier replacement of the battery may prove
necessary. The “real life” is called service life and is dened as the point at which the cell’s actual capacity has reached
80% of its nominal capacity. At the end of the service life, capacity degrades much more rapidly, so that further use of
the battery is not recommended.

Temperature eect

Temperature has the greatest impact on service life of a battery. The hotter the temperature, the earlier the wear-out phase of the
battery begins. The wear-out results in a degradation of battery capacity. See Fig 27-1 for details.

Eect of discharging cycles

The number as well as the depth of discharging cycles is limited. Replacing the battery may prove necessary earlier than the
calculated service life if the battery exceeds the numbers and values in Fig. 27-2.

Other factors shortening service life

Overcharging and deep discharging shortens the service life and should be avoided. Thanks to the single battery
concept of the 1606-XLS240-UPSE, the end-of-charge-voltage can be set very precisely to the required value, thereby
preventing unnecessary aging eects.

Charge retention is important to achieve the longest battery life. Stored batteries not fully charged age faster than
fully charged batteries. Batteries which are not in use should be recharged at least once a year.

Excessive oat charge ripple across the battery has the ect of reducing life and performance. The 1606-XLS240-UPSE
does not produce such a ripple voltage. This eect may therefore safely be ignored if you’re charging a battery with

your 1606-XLS240-UPSE.

Guidelines for long battery service life

Place the battery in a cool location, for instance near the bottom of the control cabinet.
Do not place the battery near heat generating devices.
Do not store discharged batteries.
Do not discharge the battery more than necessary. Set buer time limiter to the required buer time.
When choosing the battery capacity, always try to get the next higher capacity than the one you require.

The depth of discharge reduces the battery service life and limits the number of cycles. See Fig. 27-2.

All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.

It is assumed that the input power source can deliver a sufficient output current.

Bulletin 1606 Switched Mode Power Supplies

Example for calculating the service life and the required replacement cycle:

Parameters for the example:

A 26Ah battery with a design life of 10-12 years is used.

The average ambient temperature is 30°C.
One buer event consumes approx. 25% of the achievable buer time.
One buer event every two days

Calculation:

Ambient temperature inuence:

According to Fig. 27-1 curve C, a 5 years service life can be expected for an ambient temperature of 30°C.
Number of discharging cycles: 5 years * 182 cycles = 910cycles in 5 years.

According to Fig. 27-2, curve C has to be used (only 25% of battery capacity is required). 910 cycles have only a
negligible inuence in a battery degradation and can be ignored.

Result:
The battery shall be replaced after 5 years.
Please note that the battery degrading begins from the production date (check date code on the battery) which may
shorten the replacement intervals.

27.2. Parallel and Serial Use

Do not use the DC-UPS in parallel to increase the output power. However, two units of the DC UPS can be paralleled
for 1+1 redundancy to gain higher system reliability.

Do not use batteries in parallel, since the battery quality test might create an error message.
Do not connect two or more units in series for higher output voltages.
Do not connect two or more units in a row to get longer hold-up times.

All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.

It is assumed that the input power source can deliver a sufficient output current.

27.3. Using the Inhibit Input

The inhibit input disables buering. In normal mode, a static signal is required. In buer mode, a pulse with a
minimum length of 250ms is required to stop buering. The inhibit is stored and can be reset by cycling the input
voltage.

As long as the inhibit signal is active in normal mode, an internal relay contact will be opened and the battery will
no longer be charged.

For service purposes, the inhibit input can also be used to connect a service switch. Therefore, the inhibit signal can
be supplied from the output of the DC UPS.
