The LBC 500XTR contains a wide variety of features and protections to promote
the usability, but off course also to ensure that the charge process progresses
extremely safe.
Reverse polarisation
Reverse polarisation means that the plus and minus connection wires are
inadvertently reversed on the battery. The LBC 500XTR is protected against
reverse polarisation. The charger will not activate an
d the ‘power’ LED will light
red. Disconnect the battery and connect correctly.
Short circuit (output)
The charger is protected from short circuit when no battery is connected, even in
the presence of the main voltage.
Batteries on the other hand cannot withstand short circuit!
You should for this reason never short circuit the battery. Never short circuit
when the charger is connected to the battery, irrespective of whether the main
voltage is present. When a battery is short circuited there is a danger that it will
explode!!! The charger too will then incur serious damage.
Temperature
Because the LBC 500XTR has no fan, it is dependent on its heat loss through
the housing (passive cooling). If the internal temperature rises to high the
charger will redu
ce the charge current. Isn’t this sufficient and the temperature
keeps on rising, the charge will shut down totally. The ‘power’ LED will light up
red. When the charger has cooled down, the charger is reactivated (Power LED
green again) and the charge process will continue.
How this temperature protection progresses will strongly depend on the ambient
temperature.
Temperature sense monitoring
The temperature protection as described above, is monitored. If the charger
can’t carry out internal temperature me asurements due to a broken temperature
sensor, the charger shuts down. The ‘power’ LED will light up red. This way the
charger is maximally protected against overheating.
Soft start
The input and the output of the charger contains a soft start. This way the
charger has no influence on the DC and AC systems.
Input voltage protection
The charger is protected by means of a fuse.
Input voltage monitoring
If the input voltage drops below 180VAC, the charger will protect itself and
pauses the charge process. T
he ‘power’ will light up red. The charge process will
be continued automatically if the input voltage has risen to 190VAC again.
Automatic voltage compensation
The charger automatically compensates for the voltage drop over the connection
cables. To secure the correct working of this feature, it is preferred not to
increase the cable length. The cable can be shortened until max 1 meter.
