ELECTRONIC BATTERY CHARGER
TECHNICAL FEATURES OF THE CBHD2 SERIES
The innovative characteristics of the CBHD2 range of battery chargers are the following:
1.
Advanced technology High frequency system.
2.
Charging process fully controlled by microprocessor.
3.
Universal input voltage: 100-240 Vac
4.
Charging process start in the "soft start" mode.
5.
Automatic reset upon connection of a new battery and automatic start of a new charging
cycle.
6.
Protection against polarity inversions, short-circuits, over-voltages or anomalies by internal
fuse.
7.
Incorrect battery connection will cause the battery charger to shut down; the charger can
only be reset by the factory or an authorized service center.
8.
Signaling of possible anomalies by red LED flashing.
9.
Insensitive charge parameters in case of ±10% network voltage oscillations.
10. Efficiency > 85%.
11. Output ripple at maximum charge lower than 100mV.
12. Start of the charge cycle even with 2V batteries.
OPERATING PRINCIPLE OF THE CBHD2
On switching on a new battery charger of the CBHD2 series, the charger will check the battery
voltage and decide whether to start the charging process. If the battery is not connected to the
battery charger, the yellow LED will flash. If the result of the test is positive after 1 second the
charging of the battery can start, with the red LED on. The current of the first phase rises slowly
till the nominal value programmed is reached. If the user disconnects the battery from the
battery charger during the charging process, after a few seconds the battery charger will re-
initialize and prepare to start a new charging process. The progress of the charging process is
shown by three LED's: red, yellow and green, as in the whole range of the battery chargers. The
green LED shows the end of the charging or the last phase in case of deep charging process.
