Descriptions    DTS54 tri-phase 4-wire AC active electronic energy meter is adopting advance ASIC energy measure design, it is applicable for measurement of energy in AC electricity network. The meter is conform to GB/T17215-2002<< grade 1.0 and 2.0 static AC active energy meter>>   Features   1. The meter has the characteristic of small volume, light weight, high precision, low power consumption etc. 2. The meter has the function of bi-direction measurement. 3. The meter is adopting photoelectric coupler output test signal, LBD indicated the power consumption. The pulse of photoelectric is output proportionally with power consumption, for the different current point during the checkout, it can be chose form 1 to 16.   Main specification and technical parameter   4.Specification:   Specification and model Accuracy Rated voltage(V) Rated current(A) DTS54 1.0 3X57.5/100 1.5(6);3(6) 5(20);10(40) 20(80);30(120) 3X220/380   2.
