CB2420A
Battery Charger
Technical Features
The CB series battery chargers are designed with
advanced multi-stage battery charging method,
completely automatic and suited to meet the most
advanced requirements of battery manufacturers. The
Battery Care concept is base on algorithms that
implement rapid and automatic charging, battery charge
optimization during time, flat batteries recovery and real
time diagnostic during installation and operation. The Real
Time Autodiagnostic system, monitoring battery faults
such as, elements in short circuit, accidental reverse
polarity connection, disconnection of the battery, they can
easily be detected and removed by help of Blink Code of
Diagnosis Led; during the installation and after sell. Each
device is suited for all battery types, by means of jumpers
it is possible setting predefined curves for Open Lead Acid,
Sealed Lead Acid, Gel, Ni-Cd(option). They are
programmed for two charging levels, boost and trickle. A
rugged casing with bracket for DIN rail mounting provide
IP20 protection degree. They are extremely compact and
cost-effective.
Charging
Automatic multi-stage charging and real time diagnostic
allow fast recharge and recovery of deep discharged
batteries, adding value and reliability to the system
hosting. Type of charging is Voltages and current stabilized
IUoUo. The state of charging battery and Autodiagnosis of
the systems are identified by a flashing code on a
Diagnosis LED and Fault Battery LED:
