    Wattmeter D50561 are designed for accurate power measurement in AC and DC.
  D50561 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;
    Wattmeter D50561 -04.1 - Version 0, Division 4.1, designed for use in dry and humid tropical climate in closed rooms with air conditioned or partially air-conditioned at the ambient temperature from 1 to 45 ° C and a relative humidity of 80% at 25 ° C (GOST 15150-69).
    Technical data
    Wattmeters D50561 accuracy class 0.1 in accordance with GOST 8476-78 immediately after setting the operating mode and for any time of continuous operation.
    Basic devices D50561 indicated in the table. Rated power factor 1.0-watt meter. Rated current of the branch circuit power meter 5mA. The normal frequency range power meter from 45 to 65 Hz, the working area of 65 to 500 Hz.
    The limit of additional error D50561 devices caused by the frequency deviation from the upper limit of normal to any value in the working frequency range is ± 0,1% of the final value of the measuring range,
    The limit of additional error-watt meter D50561 caused by varying the voltage of ± 20% of nominal value at a constant value of the measured power is ± 0,1% of the final value of the measuring range. Setting time readings no more than 4 seconds.
    The limit of additional error D50561 instruments due to changes in the ambient temperature of (20 ± 2) ° C to any temperature within the operating range for each 10 ° C does not exceed ± 0,1% of the final value of the measuring range.
    The limit of additional error D50561 devices caused by the influence of external homogeneous constant or variable (frequency within the normal range of frequencies) of the magnetic field with an induction of 0.5 mT, is equal to ± 0,5% of the final value of the measuring range.
    Lighting circuit power light indicator devices D50561 is made ​​from the AC voltage (220 ± 22) at 50-60Hz transformer, can be combined with the unit, or directly from a DC or AC voltage of 4V.
