ABB ALCL-24-5+P903 68564182 Filter Module for ACS800 Drive Systems

ABB ALCL-24-5+P903, identified by ABB product ID 68564182, is a high-power filter module
associated with ABB ACS800 drive systems. The component forms part of the input-side electrical
arrangement used in large industrial drive installations. Its function is related to filtering
and controlling electrical disturbances within the drive input circuit.

The ALCL series is used in large-frame ABB drive configurations where the electrical power level
requires a dedicated filter module. Unlike a control board or an inverter power module, the
ALCL-24-5+P903 is a passive power-system component intended to work as part of the complete
drive architecture. Correct matching between the filter, drive configuration and input power
system is therefore important.

The ABB product identification for this component is 68564182, while the corresponding type
designation is ALCL-24-5+P903. ABB documentation identifies ALCL-24-5 as a filter module, and
ACS800 drive documentation shows ALCL-24-5 in high-power drive configurations.

Product Identification

Function of the ALCL-24-5 Filter Module

Power electronic drives can generate high-frequency electrical components as a consequence of
switching operation. At high power levels, controlling conducted disturbances at the drive input
becomes an important part of the overall electrical installation.

The ALCL-24-5+P903 filter module is installed as part of the drive input circuit to provide
electrical filtering. Its passive filter elements help establish the required impedance and
filtering characteristics between the incoming AC supply and the drive power conversion system.

In a complete ACS800 installation, the filter module works together with the associated drive
modules, rectifier arrangement, DC-link components and inverter modules. It should therefore be
regarded as one part of the complete power architecture rather than an independent drive controller.

Application with ABB ACS800 Drives

ABB ACS800 is a family of industrial variable-speed drive systems designed for demanding
applications. The platform includes drive modules and cabinet-based configurations covering a wide
range of motor power requirements.

ALCL-24-5 is associated with high-power configurations. ABB drive documentation shows configurations
where ALCL-24-5 is combined with R8i inverter modules. For example, an ACS800-204-0780-5 configuration
is documented with two R8i modules and an ALCL-24-5 filter arrangement.

Larger power configurations can use multiple filter modules. ABB documentation also lists
configurations where multiple ALCL-24-5 units are used with multiple R8i inverter modules. This
demonstrates that the ALCL filter selection depends on the power architecture of the complete drive.

Electrical Characteristics

Available ABB product information identifies ALCL-24-5+P903 as a high-current filter module for
three-phase AC applications. The documented electrical range associated with this configuration
includes 380–500 V AC, a rated current of approximately 945 A and a frequency range of 48–63 Hz.

These ratings place the component in a high-power industrial drive category. Such an installation
requires appropriate electrical protection, busbar or cable sizing, grounding, ventilation and
cabinet construction according to the applicable drive design and electrical standards.

Filter Architecture

The ALCL filter uses passive electrical elements to influence the current path between the AC
supply and the drive. The filter characteristics are determined by the inductive and capacitive
elements incorporated into the module.

Public technical references associated with ALCL-24-5+P903 identify typical L/C values of
approximately 39 H, 174 µF and 58 H. These values describe the filter arrangement and should not
be interpreted as a simple single-coil specification.

Because the module is part of a high-power drive system, its electrical behavior must be evaluated
together with the associated rectifier and inverter configuration. Substituting a filter with a
different electrical design may alter system impedance and operating characteristics.

Mechanical Configuration

ABB product data identifies the ALCL-24-5+P903 as a large industrial filter module. The documented
product dimensions are approximately 1397 mm in height, 573 mm in length and 240 mm in width, with
a product net weight of approximately 290 kg.

These dimensions and weight indicate that the component is intended for a substantial industrial
installation rather than a compact standalone drive enclosure. Mechanical support, lifting
arrangements and cabinet integration should therefore be considered during installation or
replacement.

The module is identified as an open-type component. It should be installed within the appropriate
electrical enclosure or system structure designed for the associated ACS800 drive configuration.

Integration into the Drive System

Correct integration requires the filter module to be connected according to the corresponding ABB
drive circuit diagram. The ALCL-24-5 documentation identifies AC input terminals and AC output
connections associated with the filter arrangement.

Installation personnel should verify the incoming phase sequence, conductor sizing, protective
earth connection, terminal arrangement and mechanical clearances before energizing the system.
The filter should not be connected based only on physical appearance because large ABB drive
systems can contain visually similar high-current components with different electrical functions.

The applicable ACS800 system documentation should also be consulted to verify which inverter or
rectifier configuration is intended to operate with ALCL-24-5.

Maintenance Considerations

High-power filter modules should be inspected as part of the overall drive maintenance program.
Maintenance personnel can inspect the module for abnormal heating, damaged insulation, loose
connections, contamination and physical deterioration.

Electrical connections are particularly important because high-current connections can generate
significant heat when contact resistance increases. Signs of discoloration, overheating or
mechanical loosening should be investigated according to the applicable service procedure.

The filter elements should also be evaluated if the drive develops abnormal input current behavior,
unexpected electrical noise or other symptoms associated with the input power circuit. Troubleshooting
should consider the complete drive rather than assuming that the filter is the only possible source
of an electrical problem.

Part Number Identification

ABB ALCL-24-5+P903 is identified by product ID 68564182. When selecting a replacement, both the
type designation and ABB product ID should be checked against the existing equipment documentation.

The suffix P903 is important because it forms part of the complete ordering designation. A similar
ALCL filter with a different current rating, voltage range or configuration should not automatically
be treated as an interchangeable component.

For maintenance records, it is useful to record the complete identification as
ABB ALCL-24-5+P903, Product ID 68564182. This helps distinguish the component from
related ALCL filter modules such as ALCL-13-5, ALCL-14-5, ALCL-15-5 and ALCL-25-5.

Related ALCL Filter Configurations

The existence of several ALCL filter sizes demonstrates why the complete drive configuration should
be checked before component selection. Current rating, voltage class, drive power, inverter module
arrangement and physical installation all influence the correct filter selection.

Typical Industrial Applications

ALCL-24-5+P903 is intended for large industrial drive installations where high-power AC input
filtering is required. The ACS800 platform is used in applications such as large pumps, fans,
compressors, conveyors, marine equipment, process machinery and other variable-speed industrial
systems.

The exact application depends on the complete ACS800 system and the motor load. The filter module
itself performs an electrical power-conditioning function and does not determine the motor control
strategy.
