For the safe operation of all electrical equipment within your Leisure Vehicle it is important that you
read and fully understand these instructions. If you are unsure of any point please contact your dealer
/ distributor for advice before use.
The following diagram shows the EC155PSU layout.
WARNING
Under heavy loads the EC155PSU case may become hot. ALWAYS ensure the ventilation slots have
a clear flow of air. Do not place combustible materials against / adjacent to the EC155PSU. The PSU
will shutdown if overheated and will restart automatically when cool.
3.1 Battery Charger / Power Converter
The EC155PSU incorporates a fixed voltage battery charger / power converter. The battery charger /
power converter also powers the leisure equipment when the mains supply is connected. This module
supplies 13.8V DC to the leisure equipment up to a maximum of 12 Amps (155 Watts), therefore the
available power is distributed between the leisure load and the battery, with the leisure load taking
priority as per the following example:
