Low Voltage Ride Through (LVRT) modules

RU19 is designed to meet the Low Voltage Ride Through (LVRT) requirements for grid connections
by staying operational during voltage dips preventing disturbances on the grid it self. 03
The RU19 is a separate module connected to the contactors coil connection A1-A2 creating a delay
function of the opening of the contactor. When controlled by PLC, the contactor is operated di-
rectly whitout delay functionality. The RU19 can be screw or DIN rail mounted.
