industry I DRP 7.0
Simple to be used and easy to set up, with a dedicated HMI graphic 4.3” touch screen.
Thanks to a retrofit kit designed for a fast and simple replacement of the old regulator.
A dedicated SW tool (MS Windows platform) allows remote support, assistance and firmware upgrade.
All the measures can be easily shared over Ethernet/Internet, and stored for data visualization/analysis.
Cascade structure (Voltage/Current/Angle Loop) with reference/limitation signals always accessible and adjustable at runtime.
PLL algorithm for precise grid angle detection also in presence of voltage harmonics.
with instantaneous switch to a secondary feedback signal or trip with controlled angle ramp down.
