3.4 Power Converter
The EC325PSU contains a power converter that powers the leisure equipment when the 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:
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 (see section 6.2 for details).
A connection harness is available from your dealer, the part number is 59065-07.
3. 6 Fuses
WARNING: When replacing fuses always replace a fuse with the correct value. NEVER
replace with a higher value / rating as this could damage the wiring harness. If a
replacement fuse ‘blows’ do not keep replacing the fuse as you could damage the wiring
harness. Please investigate the fault and contact your dealer.
