Modules capture wasted energy
A
Lenze product story

As modern servo drives machinery runs faster and faster, the amount of kinetic energy that can be saved is greater.
In many industrial processes kinetic energy is wasted by converting it into heat.
Potential energy is also wasted in machinery such as inclined conveyors and lifts.
Two new regenerative power supply (RPS) modules from Lenze take that energy and put it back into the mains, reducing energy consumption and reducing costs.
The new design suits the 9400 servo drive range and achieves a high degree of efficiency during both power supply and regenerative feedback.
This suits applications even where the regenerative power is relatively low.
The regenerative power supply modules (RPS) are available with two power ratings.
The smaller model delivers 15kW of power and is able to feed 7.5kW back into the mains.
The larger model supplies 27kW with 13.5kW available for power recovery.
They are ideal for use where either continuous or cyclic braking energy is produced.
Examples of cyclic braking include hoists and positioning drives.
Instead of converting the energy to heat via brake resistors, this energy can be easily recovered.
Energy efficiency is increased while running costs and CO emissions are reduced.
The RPS modules belong to the Lenze L-force drive and automation platform.
As modern servo drives machinery runs faster and faster, the amount of kinetic energy that can be saved is greater.
These savings can greatly influence the running and life cycle costs of a machine.
