Altech CB Type Intelligent Battery Chargers Data Sheet

CB Type Intelligent Battery Chargers

The CB type battery chargers are designed and manufactured with a
wide input voltage, single or two phase 115-230-277 VAC.

Technology

The CB series is a new range of battery chargers based on two
strategic know-how elements.

Switching technology

We have 25 year experience in design of advanced stabilized
switching technology power supplies. A battery charger based on this technology is much more efficient
and much smaller and lighter than traditional linear technology battery chargers.

Micro-processor and Battery Care

Unlike most other state-of-the-art battery chargers, the CB series is equipped with a micro-processor
which controls the charging process and enables several monitoring functions.

Maximum safety and protection

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

-Output protected against short circuit and overload -High insulation between primary and secondary

-Protection against deep battery discharge -Detection of batteries with wrong rated voltage

-Protection against reverse polarity connection -Protection against the effect of parallel connection
with other power sources, e.g. gensets.

All protections have automatic reset. No thermal fuse to be replaced.

One device for all battery types

Completely automatic, the battery chargers of the CB series are microprocessor controlled devices suited
to charging most batteries types thank to factory pre-set and selectable charging curves.
The can charge open lead acid, sealed lead acid, Bel and Ni-Cd, Ni-MH batteries. It is possible to change
or add other charging curves connecting the device to a portable PC.

Mutli-Stage charging Three charging modes

Automatic multi-stage operation and real time diagnostic allow fast recharge and recovery of deep
discharged batteries, adding value and reliability to the system hosting the CB device. The type of
charging it is Voltages stabilized and current stabilized IUoUo.
CB battery chargers feature three charging modes, identified by a flashing code on a LED.

- Boost (Boost-Bulk) (Blink 2/sec)

- Trickle (also known as float or maintenance charging) (Trickle - Float) (Blink 1/sec)

- Recovery (Recovery) (Blink 5/sec)

Recovery charging

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

Setting of battery maximum charging current

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

Diagnostic of battery and device

All CB devices support the user during installation and operation. An LED
flashing sequence code allows to discriminate among 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 wire connection.)

Diagnostic checks

Check for accidental disconnection of the battery cables

- If happen the devices switch off immediately the output power.

Battery not connected

- If the battery it is not connected no output power.

Test of quality wire connections

- During trickle charge the quality(resistance) on the battery
connection is checked

every 20 sec. this to detect if the cable connection has been properly made.

Test of battery voltage connections

- Appropriate voltage check, to prevent connection of wrong battery types.

End of charging check

- When the battery it is completely full, the device automatically switch in trickle charging mode.

Reverse polarity check

- If the battery it is connected with inverted polarity, the devices are automatically protected.

Monitor signals

Signal contracts

- CB chargers indicate battery status and faults also
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

- CV device self-diagnostic

Single output devices

Check for elements in short circuit

- Thanks to specific algorithms of evaluation,
the CBs recognize batteries worth element in
short circuit.

With the CB Battery Charger Line, Altech offers a highly reliable battery management solution. Operating at single phase Input
Voltages of 115-230-277 VAC, the devices supply an Output of 12VDC and up to 35A or 24VDC and up to 20A.

Equipped with microcontrollers, the CB line offers fully automated multi-stage charging that will expand the battery's life
significantly. Several diagnostic and monitoring features ensure easy handling and a high amount of transparency during daily
operation.

Altech's CB line battery chargers are based on the switching technology which allows much higher efficiency as well as smaller
and lighter devices. Additionally, several standard safety and protection features ensure safe installation and operation.

Technical Features

The CB series battery chargers are designed with advanced multi­stage 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,

lements in short circuit, accidental reverse polarity connection,

e
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:
