Features
–
Energy-ef²cient and optimized overall concept:
MOVIDRIVE
®
B product series extended by regenerative power supply units and
corresponding motor inverters in the power range from 160 to 315 kW
–
Particular interesting for applications with potential energy, such as in hoists, cranes and gantries, or in trolleys with high
kinetic energy produced through electrical braking
Functions
–
Used as central regenerative power supply for connected standard inverters or motor inverters
–
Energy is fed back into the grid when the application is operating as a generator, e.g. during electrical braking
–
Braking energy is no longer converted into heat but is fed back into the grid for further use
Advantages
–
Signi±cant reduction of the overall energy consumption / of CO
2
emissions / of energy costs
–
No braking resistors are required
- No investment costs for braking resistors
- No installation effort for external braking resistors
- No heating up of the environment through braking resistors
–
Sinusoidal line current = controlled energy recovery
–
With coated printed-circuit boards as standard for demanding ambient conditions
–
Simple installation and wiring: integrated PWM ±lter / integrated choke / integrated and automatic DC link precharge / in-
tegrated line contactor
–
Modular power section, which means not the entire unit needs to be replaced in the event of service
–
EMC limit value class C3 (EN 61800-3) with the standard unit
- On supply system end: without any measures
i
no external line ±lter necessary
- On motor end: with shielded motor cables and output choke
