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:
