1. General
The MASTERVOLT SOFTSTART is developed to reduce the inrush current of an isolation
transformer. When inductive loads like a transformer or electrical engines are switched on, the inrush
current can be 10 times higher than the nominal current. Often a softstarter is necessary to make sure
the shore fuse will not blow, when a shore connection is made. The inrush current is often to high for
most of the shore connections with normal fuses.
The MASTERVOLT SOFTSTART reduces the inrush current to a acceptable value.
2. Installation
The MASTERVOLT SOFTSTART must be connected between the shore connection and the
transformer, the softstart is now in serie with the shore connection and the isolation transformer.
