BAUMULLER b maXX 4100 Regenerative power supply unit

It is often the case with electrical drives that energy costs

make up almost 90% of the overall life-cycle costs. With

this in mind, regenerative systems help to reduce the total

cost of ownership.

Baumüller’s tried-and-tested b maXX automation

and drive solution is being expanded with the

addition of the new b maXX 4100 series regenerative

power supplies. These units work in conjunction

with b maXX 4400 series units, and can supply the

DC link voltage to one or more drives. By using a b

maXX 4100. all excess regenerative brake energy

generated by the system is returned to the AC

mains supply rather than wastefully dissipating

this energy as heat.

From the standpoint of energy costs, this offers the

user considerable savings over the machine’s service

life. Regenerative systems help to lower energy con-

sumption (and do their bit for the environment) by

feeding the available brake energy back to the power

grid rather than wasting it via a regenerative resistor.

The b maXX 4100 units are fully integrated into

Baumüller’s b maXX automation and drive solution

family of products. The benefits which the b maXX

series offers to its users such as modularity and

flexibility, are also provided by the b maXX 4100.

Four different frame sizes cover a DC link power

range of 35 kW to 150 kW with the option of air

or water cooling. The b maXX 4100 can also be

integrated in the Baumüller automation environ

ment by means of various optional fieldbusses.

System consistency is achieved by adopting the

same housing technology and connection arrange

ments as well as integrating the parameters of the

b maXX 4400 into the existing b maXX ProDrive

operating software.
