Sargent EC325-PSU User manual

EC325 - PSU
RV Industries Most Innovative Power Supply Unit
is used in the Wirraway 260,The Motorhome of theYear!
System Overview
These 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 Details
For 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 Charger
The 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 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.
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 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.

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 showsthe rating and circuit allocation for the three MCB’s
MCB Rating Wire Colour Description

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. Inthis 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 Converter
The EC325PSU contains a power converter that powers
the leisure equipment when the 240v mains supply is
connected. 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 the
intelligent battery charger, therefore the available
power is distributed between the leisure load and the
charger, with the leisure load taking priority as
per the following example:
Leisure load Available power for battery charger
10A 15A
15A 10A
20A 5A
25A 0A
3.5 Solar Panel Converter
The EC325PSU incorporates a built-in dual channel
Solar Regulator that 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 and
connects to the PSU via a dedicated
connector on the base of the unit.
4.1 EC 200 Control Panel
Layout and Buttons
The following diagram shows the
control panel layout and button
functions
4.4 EC 200 Control Panel Event Timer
Example: 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 hour
Ensure the clock is set to the correct time Scroll
to the ‘Set Event Timer?’ screen.
Following the instruction in section 4.3,
set the ON time to 23:00 and the OFF time to 24:00
Scroll to the ‘Event Timer=’ screen and select ON
Scroll to the main control panel display and ensure a
hash (#) is displayed in the right of the display
Turn 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 panel
Exit 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).
