<p>GV13T is one light and low price-orientated module used for checking and demonstrating Voltage, Frequency and accumulating time of generator. This module can replace old meters, for it can with multi-functions. It uses normal screw for connection which is more convenient for installation.</p> <p>Voltage, frequency and accumulating time can be checked and demonstrated in the mean time;</p> <p>Results shown by 4-position digital LED tube</p> <p>Self-recycling of parameters</p> <p>with Page Turning Buttons</p> <p>Extra working power is not needed</p> <p>Parameter demonstration:</p> <p>Phase voltage</p> <p>Frequency</p> <p>Accumulating time</p> <p>Working power: AC 70~380 V</p> <p>Consuming power:MAX:1 W</p> <p>Recycling time: Voltage:5S, Frequency:5S, Accumulating time: 2S</p> <p>Temperature: -20 ~ 75</p> <p>Size (W * H * D):58mm x 54mm x 41mm</p> <p>Installation Size(W * H): 47mm x 37mm</p> <p>Weight:50G</p> <p>Colour:black</p> <p>Material:ABS</p> <p>Package Contents:</p> <p>1 x Frequency Test Hour Meter</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
