ACS880 liquid-cooled drive modules

Compact and flexible solution

For demanding applications, where the requirements on reliability and availability are high, where the compactness and footprint of the drive cabinet is decisive, or where the environment is harsh, the new generation ACS880LC liquid-cooled drive modules offer an excellent match with the demand. The new ACS880LC module offering has a wide power range and includes a significant number of options, which enables a comprehensive offering for process optimization, uptime, reliability and provides modifiable solutions for almost any need.

The new ACS880LC drive modules offer several benefits compared with its predecessor, including up to 46% higher power density and 40% less weight. We have also ensured that the new drive is extremely reliable, by using design with even 40% less components than the previous generation modules it replaces and by performing extensive accelerated lifetime testing to meet high reliability targets.

Introduction
Drive modules portfolio
Support and integration

The liquid-cooled modules are optimized for compactness and bring the possibility to build up more compact drive cabinets than ever before. This is achieved through innovative design which features an efficient liquid cooling concept. As a result, the modules in the ACS880LC offering are very compact and have high output powers.

As the ACS880LC modules have Marine type approvals from all major Marine classification bodies and have been proven to be very robust in extensive type testing programs, it makes this offering perfectly suitable for the Marine segment, where the requirements on footprint, compliance and quality are very high.

The ACS880LC drive modules are designed to be installed into totally enclosed cabinets or enclosures as practically all heat losses are conducted into the cooling liquid. This means that there is no need to invest in additional air conditioning devices or air ducts in the electrical room. By using liquid-cooled drives, heat losses can be transferred outside from the electrical room. This is a major benefit when comparing liquid-cooled drives to air-cooled drives, as the total investment cost, compared to using traditional air-cooled drives, can be lower. Liquid-cooled drives also offer a solution where existing air-cooling capacity in an existing electrical room is not enough for new drives installations, for example in retrofits or capacity expansions. The liquid-cooled drive can also be used as a part in a heat recovery system in Process Industry. The heat losses, which are transferred from the drive to the coolant, can be reused to reduce the overall cost of primary energy. 

The concept with totally enclosed cabinets is an ideal solution for environments, e.g. in Marine segment and Process Industries like Pulp & Paper and Metals industries, where humidity, high ambient air temperatures, dust or corrosive gasses may exist. By using totally enclosed cabinets, higher uptimes and shorter plant shutdown periods can be achieved. 

Totally enclosed cabinets are especially ideal for extremely harsh environments e.g. in Mining, Tunnel-boring or any outdoor application. The totally enclosed cabinets can have very high ingress protection ratings and the drive modules can be mounted even into explosion-proof enclosures to be used in hazardous areas. This is especially useful in e.g. underground Mining applications. In addition, the compact modules can be mounted into enclosures with a low height which fit into limited space, which can be a requirement in these applications. 

 

The ACS880LC modules product portfolio includes a wide range of different products to suit all typical needs in common-DC systems, or multidrives, where several motors form a part of a single process. A multidrive typically has one common supply unit (rectifier) which converts AC to DC and feeds a common-DC bus. There are several inverter units, controlling their own motors, connected to the common DC-bus and other optional units, like brake choppers or DC-DC converters, can be connected according to needs. The energy circulates over the common-DC bus, enabling braking energy to be reused and not all energy is taken from the supply network.

This concept enables energy and cost savings, including savings in cabling, installation, and maintenance. The modules can optionally be equipped with DC-switches making it possible to isolate a unit from the DC-bus. This complete offering is an optimal solution especially for the Marine segment, as the products support DC-distribution which is typically used in hybrid and fully electrical systems in vessels. The offering includes support for shaft-generators, energy storages, off-grid networks, shore-to-ship supplies, and can control practically any motor. The modules can also be used to build standard single drives by using one supply unit and one inverter unit to control one motor. 

The liquid-cooled modules portfolio includes:

  • ACS880-104LC inverter modules (INU) – state of the art motor control DTC for practically any motor type
  • ACS880-204LC IGBT supply units (ISU) – fully controllable low-harmonic and regenerative supply unit, which can also be used as a grid converter
  • ACS880-304LC+A018 and ACS880-304LC+A019 diode supply units (DSU) – two alternative non-regenerative rectifier units, a half-controlled diode supply unit with inbuilt thyristor charging (for charging of capacitors in modules connected to the DC-bus) and a very compact uncontrolled diode-diode rectifier unit
  • ACS880-604LC brake choppers and dynamic brake units (DBU) – decelerating of motors by resistor braking
  • ACS880-1604LC DC-DC converters (DDC) – energy transfer between the common-DC bus and an external energy storage to enable energy savings, peak shaving, stability, or back-up power in critical applications and for hybrid or fully electrical systems
