DDS858 однофазный электронный вид амперметр

ResumeDDS858 single-phase electronic type ammeter is made with the advanced extr-low power consumption solid integrating technique and SMT technology, and can be used to gauge the AC active electric energy of a rated requency 50HZ. It features a high precision, good reliablility, wide loading and powerful anti-disturbance.Its performance indexes conform with the all technical requirements for the single-phase electronic type ammeter in the standards of IEC1036-1996 and GB/T17215-1998.Functions and characteristic The accuracy of the active electric energy measure is stable, it can not be affected by frequency, temperature, voltage and higher harmonic. It reduce the work of the test in the power station and the ammeter checkout greatly. Its reliablility has more inprove than other similar products. It has the function of twoway metering, can measure the positive and negative active electric energy. And use the same direction to sum the electric energy. Have a photocoupling impulse interface in the terminal box, and mark (+),(-), that can convenient to error test. The impulse output constant is as the same as the meter constant marked in the name plate, it apply to the ammeter central management system. Use special large scale integrating technique and SMT technology, it has advance technology, and laconic structure. It features a wide loading, high-accuracy, high-reliablility, high-sensitivity, flat error curve, low power consumption, small volume, light weight, energy-saving and nodal wood.Specification and main parameter Accuracy: class1, class2 Referenced voltage: 220v Basic current (the max. rated current): 5 (6), 2.5 (10), 5 (20) / 10 (40), 15 (60), 20 (80)A
