EN 61000-3-3, EN 60555-2.
CHARGE CHARACTERISTIC
MULTI XS 7000 Battery Charger has a three step fully automatic charge
profile,
Setting: 14.4 V or 14.7 V
Start
Starting phase for charging. The current is restricted to 3 A. This
phase ends when the voltage is above 10.5 V, and the charger switches
to bulk charging.
Bulk charging
Main part of the charge cycle and about 80% of the charge is returned.
The charge is carried out at maximum charge until full voltage is
achieved.
Absorbtion charging
Final part of the charge. The voltage is kept constant until the current
has dropped to a very low level.
Pulse Maintenance charging
The state of charge is between 95% and 100%. A pulse at 5 A is sent
out if the voltage drops below 12.9 V. This gives minimum water loss
and maximum life. The charger could be connected for years without
problems.
Setting: Supply
The Supply mode setting has a constant voltage at 13.6 V and current
up to 7 A. It could be used for maintenance charge using the Float
approach. This approach keeps the battery at 100 % State of Charge,
but the constant small overcharge also increases water loss. There
is no need for a battery to be connected at this mode for longer periods.
Note that the Spark Free function and the indication of Reverse Polarity
is suppressed in this mode, but the protection is still working.
Setting: Boost 16 V/1.5 A/4 h
The Boost-setting gives a constant current at 1.5 A, maximised at
16 V for 4 hours. It will automatically go over to 14.4 V pulse setting
after a completed cycle. This mode is used to recover deep discharged
batteries.
Using the MULTI XS 7000 will enhance battery life and ensure a high
degree of operational safety.
BATTERY TYPES AND PROGRAMMING
The MULTI XS 7000 can be set very easily to charge Wet, MF, GEL and
AGM lead-acid battery types. With MULTI XS 7000 you can charge batteries,
from 14 Ah to 225 Ah.
TEMPERATURE PROTECTION
To protect the charger from overheating, the MULTI XS 7000 is equipped
with a power delimiter. At raised ambient temperatures output power
is reduced. The power will also be reduced if the charger should be
accidentally covered. In this way the charger is protected from damage.
The charger continues to operate but at a lower power output. When
the ambient temperature drops the power will automatically rise again.

* Back Current Drain is what is draining the battery if the charger
is connected without the power cord connected.
** Quality of the current and voltage is very important. A linear
charger produces a current with a high ripple. High current ripple
heats up the battery and makes the positive electrode to age prematurely.
High voltage ripple could harm other equipment, which is connected
to the battery. CTEK Multi XS 7000 produces a high quality current
with very low ripple. There is no need to disconnect the battery from
the vehicle.
