Technical data

Wattmeters D50166 accuracy class 0.2 in accordance with GOST 8476-78.
The main parameters of the device D50166 Power meter on the grid. The normal frequency range power meter from 45 to 500 Hz, the operating frequency range - 500-1000 Hz. The resistance of the parallel circuit power meter for normal areas voltage 100-150 V, 200-300 V, 300-450 V and is equal to (24 ± 0,48), (48 ± 0,96) and (72 ± 1,44) kΩ, respectively.
The limit of additional error appliance power meter D50166, caused by a deflection voltage of ± 20% of nominal value, or from outside the normal range of voltages at a constant value of the measured power is ± 0,2% of the final value of the measuring range.
The limit of additional error appliance power meter D50166-induced frequency deviation from the upper limit of normal to any value in the working frequency range does not exceed ± 0,2% of the final value of the measuring range.
The limit of additional error D50166 Power meter instrument caused by changes in ambient temperature from normal to any temperature within the operating temperature for every 10 ° C change in temperature is ± 0,2% of the final value of the measuring range. Normal temperature of - 20 ± 2 ° C when the front
of the device otherwise stated value.
Changing the Power meter readings D50166 caused by the influence of external homogeneous constant magnetic field, and the field varying sinusoidally in time with frequency (within the normal region), equal to the frequency of the current flowing through the measuring circuits of the device is equal to ± 0,2% of final of the range of measurements at
value of the magnetic field, not exceeding 0.2 mT at a frequency of 1 kHz and 0.13 mT - at a frequency of 1,5 kHz.
Response time less than 3s. Dining lighting circuit unit Power meter D50166 is made from the AC voltage (220 ± 22) at 50 - 60 Hz via a step-down transformer (supplied with the devices), or directly from an AC or DC voltage (4 ± 0,4) B.
