Watt-and-varmeter D5031​​1 (D 50311, D-50311, D5031/1)

Watt-and-varmeter D5031/​​1 is designed to measure active power in three-phase three-wire AC circuits at the uniform and non-uniform load phases as well as for the measurement of reactive power in three-phase three-wire AC circuits with a symmetric voltage and load phases with the unevenness of not more than 5%.
    Accuracy class watt-and-varmeter D50311:
   
0.5 - in the modes of measurement of active and reactive power in the frequency range 45 - 65 Hz;
    1 - in the mode of measurement of active power in the frequency range of 65 to 1100 Hz.

    Rated current: 1A. Rated voltage:   100V, 250V, 375V.
    D5031/​​1 is designed to measure active power in three-phase three-wire AC circuits at the uniform and non-uniform load phases as well as for the measurement of reactive power in three-phase three-wire AC circuits with a symmetric voltage and load phases with the unevenness of not more than 5%.
    D5031​​1 is designed for use in moderate climate in enclosed dry heated rooms at the ambient temperature of 10 to 35 ° C and a relative humidity of 80% (at 25 ° C);
    Watt-and-varmeter D5031/​​1T4.1 - tropical version, designed for use in dry and humid tropical climate with an ambient temperature of 1 ° to 45 ° C and a relative humidity of 80% (at 25 ° C). Use the equipment in a dry tropical climate (version TC 4.2 category according to GOST 15150-69).
    Technical data
    Accuracy class watt-and-varmeter D50311:
    0.5 - in the modes of measurement of active and reactive power in the frequency range 45-65 Hz;
    1.0 - using active power measurement in the frequency range 65-1100 Hz.
    The nominal rate of active and reactive power - 1. Rated current parallel circuits, nominal resistance and rated inductance series circuit, scale indicated on the label of each watt-and-varmeter D5031/​​1.
    Settling time the movable part watt-and-varmeter D5031/1 to 4 at a temperature of from 18 to 22 ° C. When the temperature within the working from 1 to 45 ° C, the settling time can be increased to 16. Dimensions 140 x 200 x 95 mm. Weight less than 2 kg.
