TECHNICAL FEATURES OF THE CBHD1 SERIES
The innovative characteristics of the CBHD1 range of battery chargers are the following:
Advanced technology
1.
High frequency
system.
Charging process fully controlled by microprocessor.
2.
Universal input voltage: 100-240 Vac
3.
Charging process start in the “soft start” mode.
4.
Automatic reset upon connection of a new battery and automatic start of a new charging cycle.
5.
Protection against polarity inversions, short-circuits, over-voltages or anomalies by means of
6.
an output relay.
Battery to battery charger connection without sparks on the output terminals with obvious
7.
advantages for the active safety, thanks to the recognition of the battery voltage downstream the
normally open output relay.
Signaling of possible anomalies by red LED fl ashing or by yellow LED fl ashing.
8.
Insensitive charge parameters in case of
9.
±
10% network voltage oscillations.
Effi ciency > 85%.
10.
Output ripple at maximum charge lower than 100mV.
11.
Start of the charge cycle even with 2V batteries.
12.
OPERATING PRINCIPLE OF THE CBHD1
On switching on a new battery charger of the CBHD1 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 red LED will fl ash. If the result of the test is positive after 1 second the charging of the
battery can start, with the red LED on. The output relay closes and the current of the fi rst 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; in the
former case, the relay is opened to disconnect galvanically the battery from the battery charger.
