•
Input voltage monitoring system (to protect against deep discharge)
•
Charging current limitation to protect NiMH batteries with low input resistance and low capacity
•
Temperature limitation system to protect batteries against overheating during charging. For this purpose, the tem-
perature sensor has to be connected and have contact with the battery.
•
Limitation of operating period. When the period selected lapses, this switches the battery charger off from each
process (charging, discharging, cyclical charging/discharging).
•
Adjustable capacity limit (to protect against overcharging the battery connected)
•
Adjustable charging period (to protect against overcharging the battery connected)
•
Max. power of the electronics for charging current 50 W (select lower charging current depending on the number
of cells)
b) Maximum charge/discharge currents when the battery charger is connected to 1-V input voltage
(automatic charge/discharge current detection system)
