IU0U chargers by WAECO
… give your batteries a longer life!
Starter batteries and leisure batteries are designed for
different tasks. To start the engine, starter batteries must
supply an inital high current level and then serve as an
energy buffer with smaller, partial cycles. Leisure or
on-board batteries, in contrast, are discharged at lower
current levels over longer periods and then charged again.
This means they are subjected to considerably higher
loads. These special features must be factored into the
charging technology to protect the batteries from damage
and ensure they have a long service life. The new IU0U
battery chargers from WAECO function use a unique
six-stage charging cycle. They provide optimum charging
for all gel, AGM and wet batteries, because they charge
quickly and gently at the same time.

NEW! 6-stage IU0U charging
characteristics
1 I-phase: The discharged battery is charged with constant
current until the battery voltage reaches the charge voltage.
2 - 4 U0-phase: 3-stage absorption charging phase with constant
voltage (U0). The battery charge is determined within the first
two minutes, after which the main charging phase follows. This
ends when the battery is fully charged or the charge current is
less than 1.5 A for 15 mins.
5 U-phase: The charger switches over to float charging.
6 Conditioning: Every 12 days, the charger switches back into
phase I to revitalise the battery and prevent sulphation.

Temperature sensor/battery sensor
They are recommended when charging in highly varying or extreme ambient
temperatures. This is because battery temperature determines
the optimum charge voltage. This is reduced at high temperatures
(battery gassing prevention), and increased accordingly at low temperatures
(improved full charging).
Along with the temperature, the battery sensor determines other values
which help the battery charger to optimise the charge process (battery
terminal voltage, charge current, charge status). Voltage losses from
the charge cables can therefore be compensated.
Two bus interfaces as series standard
This makes the new PerfectCharge battery chargers optimally prepared for all current, and
future, innovations the caravan industry has in store. Their bus compatibility makes connecting a
battery sensor or integrating them into a management system, such as the MPC 01, particularly
easy.
DIP switches
Four dip switches allow the optimum charging characteristics for the battery type connected
(gel, AGM or wet battery) to be configured. Switchover and float voltage can be set in accordance
with the battery manufacturer's specifications.
Digital interface
Interface for connecting an external functional control or an external switch, which can be used
to switch the charger into sleep mode, for example.
Contents, specifications and availability are subject to change due to the technical improvement.
