Optimized Design: Battery can represent a significant part of UPS budget in greenfield or brownfield projects. That’s why PESS RBC-02/06/12 is designed with a wide output DC voltage range to optimize:
-Number of battery cells.
-Battery capacity and therefore the price, as per the required autonomy.
-Various solutions to operate with the differing input voltage networks (nominal value, tolerance, frequency).
-Various LVD and Dropper configurations to get flexible design.
Make easy to replace complete power electronic parts of product thanks to modul-type design, easy maintenance
High MTBF above 100 000 hours with appropriate maintenance plan
Customizable fault and status 8 or 16 relays for enhanced interfacing whit existing DCS and SCADA systems
Thanks to modular design of power electronic control parts, specialized designs are possible with LVD, diode droppers or dc/dc converter regulators.
