3. Technical features 

 
The ERS is a regenerative power supply unit with optimized price-performance ratio and high degree 
of protection, thus, the use is already worthwhile even with small energy surplus quantities.

 

 Assembly 

is made with mounting aids directly on the device. 
 
The centerpiece is a DSP signal processor for generating the pulse pattern and addressing all 
applicable control tasks and to safeguard the integrated protection functions. 
 
Through advanced semiconductors and sophisticated control technology and control engineering, 
enables the device to recover energy with an efficiency> 95% 
 

3.1. Special features  

The ERS is directly connected to the intermediate circuit of the inverter or the servo controller. The 
voltage is monitored and upon reaching the respective threshold the feedback mode is automatically 
activated. 
 
The thresholds are adjustable via a selector switch inside the unit 
 
The ERS operates on 3ph AC voltage network and synchronizes automatically at the connection. 
 
There is no programming required. The device is immediately ready after turning on the inverter or the 
servo controller and the synchronization with the utility grid. 
 
 

High operational safety due to: 
 

 

•

 

High interference immunity and low noise emission by built-in filters 

•

 

Electrically isolated enable input  

•

 

Electrically isolated digital output (for example: synchronization successfully) 

•

 

Device temperature monitoring of critical components 

•

 

Current monitoring and shutdown 

•

 

Continuous monitoring and measurement of all 3 mains phases 

•

 

Continuous monitoring and measurement of the intermediate circuit voltage 

•

 

Preset device parameters 

•

 

Easy handling 

•

 

Fast commissioning
