ELECTRONIC BATTERY CHARGER OPERATING
TECHNICAL FEATURES OF THE CBHD1 – CBHD2 - CBHD3 - HF1-IP
The innovative characteristics of the CBHD1 – CBHD2 – CBHD3 - HF1-IP 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. Available on request automatic Reset on insertion of a new battery and automatic charge cycle
start.
6. Protection against polarity inversions, short-circuits, over-voltages or anomalies by means of an
output relay.
7. Battery to battery charger connection without sparks on the output terminals with obvious
advantages for the active safety, thanks to the recognition of the battery voltage downstream
the normally open output relay.
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 CBHD1 – CBHD2 – CBHD3 - HF1-IP
On switching on a new battery charger of the CBHD1 – CBHD2 – CBHD3 – HF1-IP 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 output relay closes and the
current of the first phase rises slowly till the nominal value programmed is reached. If during the
battery charge process the user disconnects the actual battery from the battery charger, after a few
seconds the battery charger will reset and get ready to start a new charge process (available on
request). 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.
