Rectifiers

ADC II
General
his rectifier range is suitable for boost and float-charging
T of stationary installations. The low power ranges, are also
suitable for charging starter-batteries for diesel motors or gas
turbines.
Integrated function
he ADC is equipped with an active filter for sinusoidal
T current consumption on the mains input. Using this technology
a power factor of nearly 1 can be reached. This means
that only actual power is taken from the supply to feed the ADC.
Because the ADC has a very low output ripple current, it is ideally
suited to be used with sealed batteries. The ADC can also be
connected to loads without batteries because of its excellent
dynamic performance.
These units can be supplied in a 19" plug-in version (see picture
1), as module (see picture 2) or in a wall-mounted version
(see picture 3).
The output is accurate, with constant power characteristic and
equipped with 3 different voltage levels as well as a current
limiting.
For optimizing the battery service life of sealed batteries temperature
compensated charging voltage regulation is possible.
The unit is cooled with a fan which is temperature controlled
and superviced by a max. temperature guard.
