EC325 - PSURV Industries Most Innovative Power Supply Unit

is used in the Wirraway 260, The Motorhome of the Year!

System OverviewThese diagrams show 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 ancillary components and the EC325 digital control panel.

EC325 Power Control System Overview - Key Features •325W (~25A) Power Converter - Converts the 240v 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 for automatic operation for 12v diesel heater, lighting, alarm system & 240v airconditioner via a relay. • The key component is the EC325 power supply unit (PSU), which is the hub of the system and provides connectivity to the ancillary components and the EC325 digital control panel.

EC 325 Power Supply DetailsFor complete operation details refer to our Instruction & Specifications Manual available from Wirraway Motorhomes as a PDF document that will be emailed to you on request. Some of this information is included in the following text and illustrations, refer to instruction manual for full operating instructions.

3.1 Battery ChargerThe EC325PSU incorporates an intelligent ‘offline’ battery charger that disconnects the leisure equipment from the battery while it is being charged. This process allows the charger to use higher charging voltages and to accurately control the charging current.No other equipment may be connected directly to the battery while charging is taking place. This intelligent battery charger draws power from the power converter when the mains 230v supply is turned on and from the vehicle alternator when the engine is running, therefore the leisure battery is always charged via the intelligent battery charger. The charger can be preset at instillation for either Gel or Lead Acid batteries.

The EC325 system also incorporates a battery compartment temperature sensor, which monitors the battery ambient temperature to allow the charger to adjust the charging current if the battery is very cold or hot to optimise performance.

3.2 Residual Current Device & Miniature Circuit BreakersThe Residual Current Device (RCD) is basically provided to protect the user from lethal electric shock. The RCD will turn off (trip) if the current flowing in the live conductor does not fully return down the neutral conductor, i.e. some current is passing through a person down to earth or through a faulty appliance.To ensure the RCD is working correctly, the test buttonshould be operated each time the vehicle is connected to the mains supply.

The Miniature Circuit Breakers (MCB’s) operate in a similar way to traditional fuses and are provided to protect the wiring installation from overload or short circuit. If an overload occurs the MCB will switch off the supply. If this occurs you should investigate the cause of the fault before switching the MCB back on.

3.3 System MonitorThe system monitor circuit checks the power supply key components to ensure optimum operation. The current status is displayed on the front of the PSU by the means of a clear indication that illuminates in different colours depending on the PSU status.

3.2 Residual Current Device & Miniature Circuit Breakers

The Residual Current Device (RCD) is basically provided to protect the user from lethal electric shock. The RCD will turn off (trip) if the current flowing in the live conductor does not fully return down the neutral conductor, i.e. some current is passing through a person down to earth or through a faulty appliance. To ensure the RCD is working correctly, the test button should be operated each time the vehicle is connected to the mains supply (see section 5.1) The Miniature Circuit Breakers (MCB’s) operate in a similar way to traditional fuses and are provided to protect the wiring installation from overload or short circuit. If an overload occurs the MCB will switch off the supply. If this occurs you should investigate the cause of the fault before switching the MCB back on.

The following table shows the rating and circuit allocation for the three MCB’s

MCB Rating Wire Colour Description

1 10 Amps White 230v Sockets

2 10 Amps White (Yellow for heater) Extra 230v Sockets / Heater

3 6 Amps Black (Blue for water heater) Fridge / Water Heater / 12v Charger (internally connected)

3.3 System Monitor

The system monitor circuit checks the power supply key components to ensure optimum operation. The current status is displayed on the front of the PSU by the means of a clear indication that illuminates in different colours depending on the PSU status.

Status Indication description

- - G Good Mains supply on, PSU status good.

- - - Good Mains supply off, PSU status good.

- O G Warning

Mains supply on, PSU in warning mode. In this mode the PSU will limit the output current to protect the unit from damage. It is still safe to use the unit but the fault should be investigated. Typical causes are battery temperature sensor unplugged, cooling fan not working, internal sensors disconnected or failed.

- O - Warning Mains supply off, PSU in warning mode.

R O G Failure

Mains supply on, PSU in overheat failure mode. In this mode the PSU will shutdown and all equipment will be switched off. The cooling fan will continue to run until the unit cools down. Typical causes are short-circuited DC output, battery connected in reverse, cooling fan failed, cooling vents blocked / covered, problem caused by prolonged use in warning mode.

R - G Failure Mains supply on, PSU in overheat failure mode.

R O - Failure Mains supply off, PSU in overheat failure mode.

3.4 Power ConverterThe EC325PSU contains a power converter that powersthe leisure equipment when the 240v mains supply isconnected. This module supplies 13.5v DC to the leisure equipment up to a maximum of 25 Amps (325 Watts).

The power converter also supplies power to theintelligent battery charger, therefore the availablepower is distributed between the leisure load and thecharger, with the leisure load taking priority asper the following example:

Leisure load Available power for battery charger 10A 15A 15A 10A 20A 5A 25A 0A

3.5 Solar Panel ConverterThe EC325PSU incorporates a built-in dual channelSolar Regulator that allows the direct connectionof a 20 to 100W solar panel without the need for additional components. The dual regulator chargesboth the vehicle and leisure batteries simultaneously and connects to the PSU via a dedicatedconnector on the base of the unit.

4.1 EC 200 Control PanelLayout and ButtonsThe following diagram shows the control panel layout and button functions

4.4 EC 200 Control Panel Event TimerExample: The event timer is designed to allow the leisure vehicle user to turn the 12v power on or off(in the same way as using the control panel power button) without being in the vehicle.This allows to turn ON or OFF at a predetermined time your 12v diesel heater, lighting, alarm system and your 240v airconditioner via a relay.Example:To turn on one interior light at 11.00pm for 1 hourEnsure the clock is set to the correct time Scrollto the ‘Set Event Timer?’ screen.Following the instruction in section 4.3,set the ON time to 23:00 and the OFF time to 24:00Scroll to the ‘Event Timer=’ screen and select ONScroll to the main control panel display and ensure ahash (#) is displayed in the right of the displayTurn all lights and 12v equipment off in the vehicle except the light that you want the event timer to automatically switch on Turn the 12v power off on the control panelExit the vehicle.At 11:00pm (23:00) the control panel will switch the 12v power on and therefore any equipment that was left switched on will be turned ON.The 12v power will be switched OFF at Midnight (24:00).
