wattmeter & nbsp; D50161 & nbsp; are designed to measure current, voltage and power in circuits & nbsp; . AC and DC
Specifications
& nbsp; & nbsp; & nbsp; D50161 power meter corresponds to the class of accuracy of 0.2 according to GOST 8476-78 immediately after turning on and within any time continuous operation & nbsp;.
& nbsp; & nbsp; & nbsp; Normal wattmeter D50161 frequency region of 45 to 500 Hz, the operating frequency range & ndash; 500 to 1000 Hz, & nbsp;.
& nbsp; & nbsp; & nbsp; The limit of tolerable additional error wattmeter D50161 induced voltage deviation of & plusmn; 20% of the nominal value measured at constant power equal to the limit of tolerable basic error & nbsp;.
& nbsp; & nbsp; & nbsp; Changing Power meter readings D50161 caused by change in frequency from the upper limit of normal field to any value in the working frequency range does not exceed & plusmn; 0.2% of the final value of the measuring range
& nbsp;. & Nbsp; & nbsp; Limit device tolerable additional error wattmeter D50161 caused by the influence of the external homogeneous DC or AC (frequency within the normal range of frequencies, but no more than 1 kHz) of the magnetic field with magnetic induction of 0.2 mT, does not exceed & plusmn; 0.2% of the final value of the measurement range & nbsp;.
& nbsp; & nbsp; & nbsp; settling time readings no more than 4s. Power supply circuit device wattmeter D50161 illumination produced by the AC voltage (220 & plusmn; 22) V 50 & ndash; 60 Hz via a step-down transformer (supplied with devices) or directly from an AC or DC voltage 4B
& nbsp;. & Nbsp; & nbsp; Overall dimensions wattmeter D50161 no more 205h290h135 mm unit weight of not more than 4.5 kg. Dimensions of the transformer housing is not more 65h85h45 mm, the transformer weight no more than 0.5 kg.
