BATTERY CHARGER NE143-PBATTERY CHARGER NE143-P
GBGBGBGB
DESCRIPTION:
The NE143-P is a charger for lead and gel storage batteries. The batteries should have nominal voltage of
12V and capacity of no less than 50Ah.
OPERATION:
The battery charger uses a combination of CC (Constant Current) and TC
(Constant Tension) when charging. This makes it possible to significantly reduce
charging time and avoids permanent damage to the batteries. The charger starts charging
with CC until the battery reaches a tension of VOC, after which it switches to TC operation.
At this stage the device supplies constant voltage of VOC/VF (14.4/13.8 GEL-14.7/13.8 Pb), charging current
reduces gradually and the battery can be left permanently connected to the battery charger without problems.
CHARGING PROFILES:
Use the switch located on the front of the panel to select the charging profile according to the type of battery
to be charged.
ATTENTION :
- Keep the device in a dry well-aired place. - If the power lead or battery connection clamps are
