All the line voltages are monitored and sensed simultaneously using three independentscale down potential transducer this low level ac signal is subjected to signal condition,which includes surge suppressors and harmonic filter, filtered signal is fed to the ADC of theindustrial grade pic micro controller, When the sensing voltage level exceeds the user setvalue f or under or over voltage, Digital Microcontroller based definite-time under voltage(uv) and over voltage (ov) relay/line voltage monitor(LVM) gives an output signal in the formof relay change over for tripping/alarming. Specification Site selectable system voltage Continuous display of the measured voltage parameter 16 character 2 line LCD display with back-lit Accurate reading for balanced and unbalanced load Wide range of auxiliary input for both AC & DC Independent contacts for both Under & Over voltage Self reset & site selectable reset gap Built in fixed instantaneous Under & Over voltage highest trip User friendly setting modes using key pads Low power consumption Tropicalized design using micro controller & Ideal for industrial environment
