TECHNOLOGY

INTRODUCTION
The MASS battery charger is a fully automatic high-effi-
cient battery charger/rectifier,developed and produced by
Mastervolt Amsterdam. The MASS series goes with a
family of advanced quality battery chargers. Mastervolt
distributes these products worldwide. The battery charger
posseses an outstanding charging technique in order to
charge batteries rapidly, safely and in the same time sup-
ply the connected consumers. In addition, the charger is
secured against short circuit, overload and high tempera-
tures in an industrial enviroment.
THEORY OF OPERATION
The MASS battery charger has a three-step charge
characteristic (see fig. 1).
