Prok dvs make AC Digital Microcontroller Based Definite-Time Under Voltage (UV) and Over Voltage (OV)/ Line Voltage Monitor (LVM) is a microcontroller based voltage monitoring and supervision relay for poly-phase system. It can monitor both under voltage (UV) and over voltage (OV) conditions in the system. Both under voltage (UV) & over voltage (OV) conditions are associated with definite time tripping characteristics. It has wide setting range of operating time on the occurrence of fault condition.
DIGITAL MICROCONTROLLER BASED DEFINITE TIME UNDER VOLTAGE (UV) AND OVER VOLTAGE RELAY/ LINE VOLTAGE MONITOR(LVM) provides wide range of time delay for healthy resumption of the operating voltage.
