EnergyMode: Energy mode
A standard MDP90A power supply module is used to supply the DC link of the application inverters in energy mode.
The MDE90A DC/DC converter module connects the external energy storage unit to the DC link. The DC/DC converter module is directly connected to the DC link and decouples the storage unit from its voltage. In this way, the storage unit can be designed for an extended voltage range, and does not depend on the voltage of the DC link.
The system can absorb regenerative energy from the DC link and make it available again later. A braking resistor is not required, and the dual-powered MDS90A 24 V switched-mode power supply module can supply all 24 V devices and control the behavior of the system in the event of a power failure.
The advantages of EnergyMode are:
- Reduction of the grid load
- Reduction of energy costs
- Suitable for large energy volumes
- Power fail-safe covering outages lasting several minutes
- The energy storage unit is decoupled from the DC link via the DC/DC converter module.
The following figure shows the functional principle of the Power and Energy Solutions components in EnergyMode:
