Operating instructions
Electric-System EVS 34/12-DS/IU
Purpose
The Multifunction Electrical Power Supply is a combination of an automatic
charger and a voltage booster. It is used to supply electrical power at 12 V, and
for charging 12 V lead-acid accumulators consisting of six individual cells with
a battery capacity of between 60 and 120 Ah (e.g. car batteries).
It can be used anywhere, and has been designed for continuous operation.
The EVS is particularly suitable for use in mobile homes. It is equally suitable
for batteries with gel and liquid electrolytes.
Inappropriate use
Do not use with 6 volt batteries or with
non-rechargeable batteries!
The EVS must not be used to charge 6 V lead-acid batteries. If batteries with a
rated voltage of 6 volt are charged with the EVS, gas is created immediately.
Explosive oxyhydrogen gas is generated.
The EVS must not be used to charge non-rechargeable batteries and/or nickel-
cadmium batteries.
When charging these battery types with the EVS, the outer cover may rupture
explosively.
Description
The multifunction electrical power supply employs the latest charging techno-
logy. This technology permits high output together with low weight and small
dimensions. By using high-quality electronics, it works with almost no power
loss.
Automatic charging affords protection and prevents harmful battery overload.
This considerably extends the life of the battery.
The EVS has a charging output for the supply battery. When operating, the
control electronics checks the battery's terminal voltage and whether the battery
is connected with the proper polarity.
The EVS is designed for parallel operation and buffer operation. At all times,
consumers can remain connected, be added or switched off. Consumers are
supplied with the power and the battery is charged at the same time. Current
taken from the battery is immediately recharged. Consumer current should
