Product description
The Power and Energy Solutions product range expands SEW-EURODRIVE’s current line of MOVIDRIVE® modular inverters to include intelligent power and energy management components.
This way, solutions in the field of system and machine automation meet the highest standards regarding energy and power efficiency as well as supply reliability. The system allows for significantly smaller and simpler connection solutions in terms of grid infrastructure. Compared to conventional supply units, there is a significant saving potential when it comes to installation and operation of multi-axis systems.
You can establish supply reliability (uninterruptible power supply) in addition to normal operation of the system by means of active use of the storage technology. This ensures safe operating states and rapid restarts in case of interferences in the supply system.
Energy cost savings of 20 to 30% can be achieved in a multi-axis system with the system.
The Power and Energy Solutions product series consists of:
- Power supply modules with controlled DC link voltage.
- Energy converter (DC/DC converter) for integrating external energy storage units.
- Capacitor modules and power interface to external energy storage units (double-layer capacitors).
- 24 V switched-mode power supply modules with AC and DC supply.
- MOVIKIT® Power and Energy Solutions software modules for the control technology.
Also standard, electrical energy storage units such as capacitor modules and double-layer capacitor storage units can be connected to MOVIDRIVE® modular application inverters.
Using Power and Energy Solutions has the following advantages:
- Peak load reduction by factor 4 to 15.
- Savings in the grid infrastructure of the customer through a smaller and more flexible design of all supply components in the control cabinet (smaller cable cross sections, more favorable safety and switching elements, smaller filter technology or no filter technology).
- Recovery and storage of regenerative power.
- System operation without braking resistor or with significantly smaller braking resistors.
- Power failure protection with variable scalability with the function of an uninterruptible power supply. The use of an additional back-up battery is not required.
- Power supply for control cabinet and multi-axis system for various line frequencies and voltages that is independent of line parameters, which allows for consistent drive selection worldwide.
- Grid-independent DC link voltage, which means independent drive selection worldwide.
- Power adjustment and power increase by means of dynamic variation of the DC link voltage.
- Energetic online monitoring of the application (DriveRadar®).
- Real time measuring of energy productivity index (energy per cycle or per unit).
- Monitoring of energetic consumption according to ISO 50001.
- Reduction of grid disturbances and improved grid quality by avoiding load peaks and by significantly lower harmonic emissions.
- Operation of the multi-axis system on pure DC grids (operation of the energy converter as a supply unit). For example, on external battery systems or future industrial DC grids.
In order to extend the functional scope of the basic units, products from the Power and Energy Solutions product range can be operated on a single controller. A powerful and clock-synchronized connection is available for this with the EtherCAT®/SBusPLUS integrated communication interface. Additional EtherCAT® stations from SEW-EURODRIVE or other manufacturers can be controlled and diagnosed by the MOVI-C® CONTROLLER.
The devices in the product range are supplemented by special MOVIKIT® software modules for optimum integration in the controller software level.
