TUNKIA TD3600 Three-phase Energy Meters Verification Device

TD3600 Three-phase Energy Meters Verification Device

TD3600 is a dedicated verification device for the initial and subsequent verification of three-phase AC energy meters. It mainly consists of a three-phase precision standard power source, a multi-position meter test bench, a control console, an optional computer, and dedicated software. Available in two accuracy classes—0.02 and 0.05—it is based on the high stability and accuracy of the three-phase standard power source, and works in conjunction with specialized computer software to support fully automatic simultaneous verification of 3 to 16 electromechanical or electronic three-phase energy meters with identical voltage/current ranges but different meter constants.
