USER MANUAL
•Read this instruction before the charger is taken into use
•Keep this manual within easy reach for the user of this battery charger
•During charging, the batteries must be placed in a well-ventilated area
•Always connect the positive cable to the battery first, then the negative to the chassis. The battery
charger is then to be connected to the mains.
•Hydrogen gas will be produced when charging lead-acid batteries and hydrogen gas is explosive
•Open flames and sparks should be kept away from batteries they may produce explosions
•After charging, disconnect the battery charger from the supply mains, then remove the chassis
connection and then the battery connection
•The supply cord cannot be replaced. If the cord is broken the appliance should be scrapped
•Do not cut the negative cable without taking necessary action, see page 14!
General
The chAmp Charger is suitable both for Freely Ventilated- (Wet) and Valve Regulated- (Dry) lead/acid batteries.
The charger is small and very compact and can therefore easily be fitted close to the battery.
The charger operates in high frequency and should be connected to a standard 230V mains connection with ground.
The built in micro controller controls the charging process according to the chosen charging algorithm.
During charging the charging progress is displayed with status indicator LED on the front panel. The micro-controller
is also controlling the charging progress with regards to temperature in the charger and time. If a fault occurs in
some cells or the temperature rises the charging current will be limited. If you have a special requirement of
charging algorithm or application, please contact Primepower AB.
Installation
The chAmp Charger is suited for indoor and outdoor use.
It can be used positioned horizontally on a table or a shelf, hang on a wall or as a built-in charger in the vehicle or
machinery. The charger can be with fixed connection to the battery or with conventional connectors.
Position the charger in such a way that the air supply will not be obstructed.
When the charger is fitted on a wall or mounted in a vehicle it should preferable be vertical mounted for optimal
cooling. The battery charger will reach temperatures above +41Cowhile running and shall there by be mounted
unreachable for the user, if mounted on a wheelchair or any kind of help vehicle.
Function
Start by choosing your battery type or Power supply mode with the ”Mode” button. The recharging process will start
after a few seconds and you will see the lower yellow LED will light up. The charger will start with the same
configuration as before you disconnect the mains. The different stages of charging will be indicated by the LED lights
throughout the charging process. When the charger sense that the battery is full the green LED will light up and the
charger will automatically go over to maintenance charge, the charger will hold this stage until you unplug it.
If the charger sense that anything is wrong the red LED will light up. To restart the charger you have to either unplug
the mains or disconnect the charger from the battery. The charger has a built in temperature sensor so the charger
can compensate the charging process to the correct temperature. The temperature sensor is built in the negative
ground cable (black cable). The power supply mode will give a steady output of either 13,7V or 27,5V.
A freely ventilated battery (Wet) can be discharged to max. 80% and a valve regulated (Dry) with max 70%.
