Description
5.1
Application
The machine may only be used for the operation of internal and external vibra-
tors.
The machine is used to convert the current on the construction site into current
that can be used by the machines to be connected.
5.2
Functionality
Principle
The machine converts the current on the construction site (e.g. 230 V 1~) in or-
der to operate machines with special specifications. Voltage, frequency and
phase number are adjusted during this process.
Machine features
Short-circuit and earth-fault proof.
Shutdown in the case of excess temperature and fault voltage.
Overload current detection.
Protective low voltage provided by safety isolation transformer (applicable to
42 V machines).
Inverter
The inverter comprises a current rectifier and a d.c.-a.c. converter monitored by
an electronic control.
The current rectifier converts the input voltage (AC single phase) to DC voltage.
The d.c.-a.c. converter converts the generated DC voltage to three phase current
(AC three phase).
When the machine is switched on, the control electronics provides a soft start
and thus prevents critical starting currents.
