+91-922 800 4452/53/54


The VAF model meters from Trinity are True RMS type digital meters for use in three phase four wire LT electrical systems. The design of these meters is based on proven micro-controller technology, resulting in compact and accurate meters. The design uses powerful micro-controller based technology. The meter uses state of the art Digital Signal Processing (DSP) circuitry to achieve very high accuracy measurement of True RMS value of all parameters. The meter displays the readings on Crisp Super bright LED Displays.
