EC325 PSU - Power Control Unit Key Functions

· 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.

RV EC155 PSU & EC 51 Power Management Systems


Wirraway's EC51 Control Panel & EC155 Power Supply Unit

is a simpler version of the more advanced EC200

Key Features
150W (~12A) combined Power Converter / Battery Charger - Converts the 230V mains supply into 12v DC power to run the leisure equipment and charge the battery.

Low current switching reduces voltage drop in the circuit and improved circuit fusing provides better protection for the harness and equipment.

Links to the EC50 series LED Control Panel to provide simple but intelligent control of the 12v equipment and built in over discharge software protects the leisure and vehicle batteries.

System Overview
The following diagram shows the typical configuration of the EC155 system.

The key component is the EC155 power supply unit (PSU), which is the hub of the system and provides connectivity to the ancillary components and the EC50 series control panel.
