One device for all battery types

Completely automatic, the battery chargers in the CB series are micro-processor controlled devices suited to charging most battery types thanks to factory pre-set and selectable charging curves.
They can charge open lead acid, sealed lead acid, Gel and Ni-Cd, Ni-MH batteries. It is possible to change or add other charging curves by connecting the device to a portable PC.

Multi-Stage charging - Three charging modes

Automatic multi-stage operation and real time diagnostics, allow fast recharge and recovery of deeply discharged batteries, thereby adding value and reliability to the system hosting the CB device. The type of charging is voltage stabilised and current stabilised (IUoUo).
CB battery chargers feature three charging modes, identified by a flashing code on a LED.

• Boost (Boost - Bulk) (Blinks 2/sec)
• Trickle (also known as float or maintenance charging) (Trickle - Float) (Blink 1/Sec.)
• Recover (Recovery) (Blinks 5/sec.)

Recovery charging

The automatic multi-stage operation optimises and adapts to the battery status, even when the battery voltage is very low. The CB can recharge batteries even when their voltage is close to zero. It allows the recharge and complete recovery of flat batteries.

Setting the maximum battery charging current

The maximum battery charging current can be set from 20% to 100% of the devices rated value.  Not available on LC models.

Battery and device diagnostics

All CB devices support the user during installation and operation.
An LED flashing sequence code allows the user to discriminate between various possible faults.

LED Diagnosis:

• 1 flash - Reverse polarity, wrong battery voltage.
• 2 flashes - Disconnected battery.
• 3 flashes - Battery element in short circuit.
• 5 flashes - Battery to be replaced (Internal impedance bad or bad battery cable connection).

Maximum safety and protection

The CB series is designed to provide safe operation and long battery life. The following are standard features:

• Output protected against short circuit and overload
• Protection against deep battery discharge
• Protection against reverse polarity connection
• High insulation between primary and secondary
• Detection of batteries with an incorrect voltage rating
• Protection against the effect of parallel connection with other power sources, e.g. gensets.

All forms of protection have an automatic reset. No thermal fuse to be replaced.

Monitoring signals

Signal contacts

• CB chargers indicate battery status and faults via a change-over contact with galvanic isolation.
• Battery common fault.
• Unit disconnected from mains.

Visual indication

• Battery common fault
• Unit disconnected from mains
• Charging mode
• CB deviced self-diagnostic

Diagnostic checks

• Check for accidental disconnection of the battery cables - If this occurs the device switches off the power to the battery.
• Testing the quality of the cable connections - During trickle charge the quality (resistance) of the battery connection is checked every 20 sec. This is to detect if the cable connection has been properly made.
• Test of battery voltage
• Appropriate voltage check - to prevent the connection of incorrect battery types.
• End of charging check - When the battery it is completely charged, the device automatically switches to trickle charge mode.
• Reverse polarity check - If the battery it is connected with inverted polarity, the devices are automatically protected.
• Check for elements in short circuit - Thanks to specific algorithms of evaluation, the CBs recognise batteries with elements in short circuit.
