2 SAFETY NOTICES
Each shore power converter is capable of transferring large amounts of electrical energy very
quickly. This quality is fundamental to a high performance power converter. International symbols
are used throughout this manual to stress important information. Read the text below each symbol
carefully and use professional skills and prudent care when performing the actions described by the
text.
THE CAUTION SYMBOL (TRIANGLE ENCLOSING AN EXCLAMATION POINT)
INDICATES A CONDITION THAT COULD SERIOUSLY DAMAGE EQUIPMENT AND
POSSIBLY INJURE PERSONNEL. CAUTIONS WILL BE PRESENTED IN THIS FORM.
ALL CAUTIONS SHOULD BE RIGOROUSLY OBSERVED.
THE WARNING SYMBOL (TRIANGLE WITH A LIGHTNING BOLT) IS USED TO
SIGNAL THE PRESENCE OF A POSSIBLE SERIOUS, LIFE THREATENING
CONDITION. A CONDITION THAT IS HAZARDOUS TO BOTH PERSONNEL AND
EQUIPMENT WILL BE ISSUED AS A WARNING. ALL WARNINGS WILL BE
PRESENTED IN THIS FORM.

3 INTRODUCTION TO THE AC125V-3
The AC125V-3 is a high performance Yacht Power Converter utilizing dual-conversion technology.
The system will accept any three phase input service with a frequency between 40-70Hertz, and a
voltage between 330-520VAC.
The output power form has been programmed at the factory for the voltage and frequency required
by your yacht.
Dual-conversion technology is the preferred technique for AC power conversion, and was chosen
for the system. In this technology, the shore power service is isolated by the transformer, then
converted to DC power by the phase multiplier power supplies. The output inverters then convert
the DC power back to the required AC form (both voltage and frequency) required by the yacht.
Being a converter designed from the ground up specifically for the yachting industry, all efforts have
been made to produce a system capable of withstanding the marine environment. All system

components are packaged in one drip-proof, dust-resistant stainless steel enclosure. Major
components are internally modular, allowing a simple exchange in the unlikely event of failure.
Complete maintenance and service can be provided with only top and front access to the system.
Three lightweight power modules can be removed and replaced through the front panel for repair
or power level upgrade.
System operation is managed through three basic operators. A safety disconnect on the front of the
enclosure is used for securing input service during maintenance and service. Three membrane switch
groups in the control console, SHORE POWER, CONVERTER POWER, and SHIP’S POWER,
provide normal operation of the system. Each switch group contains an ON and OFF switch with
associated LED indicators.
In addition to the basic function of power conversion, the converter provides the user with a
sophisticated power analysis and monitoring capacity. All parameters for input and output power,
along with operations and status information, are available on the front panel display console.
Various displays are selected through a long life, sealed membrane switch panel.
For additional information on controls and indicators, please refer to Section 6.
