1 Key Features

·
325W (~25A) Power Converter - Converts the 230V mains supply into 12v DC power to run
the leisure equipment and supply the battery charger.
·
Intelligent 'offline' Battery Charger - Uses a process of disconnecting the leisure battery from
the leisure equipment during the charging process, which allows the battery charger to
charge batteries quicker, recover heavily discharged batteries and achieve a higher final
charge level than traditional battery chargers.
·
Built-in dual Solar Regulator - Allows the direct connection of a 20 to 100W solar panel
without the need for additional components. The dual regulator charges both the vehicle and
leisure batteries simultaneously.
·
System Monitor Circuit - Monitors key components within the power supply to ensure
optimum operation. A simple 'traffic light' indicator shows the power supply status.
·
Enhanced Digital Control Panel - With scrolling menu system, battery condition (voltage and
current), water tank levels, tank and battery level warnings with battery protect circuit, alarm
clock and programmable event timer.

2 System Overview

The following diagram shows the typical configuration of the EC325 system. The key component is
the EC325 power supply unit (PSU), which is the hub of the system and provides connectivity to the
