D5089 are designed to measure power in single-phase AC and DC motors, and also for testing less precise instruments.
Wattmeter D5089 are designed for use in moderate climate in enclosed dry heated rooms, at an ambient temperature of 10 ° to 35 ° C and a relative humidity of 80% (at 25 ° C).
Wattmeters D5089 -04.1 (tropical version) designed for use in both 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 D5089 accuracy class 0.2 in accordance with GOST 8476-78.
The main parameters of the device power meter D5089 listed in the table. Rated power factor wattmeter - 1.0. Rated current of the branch circuit power meter D5089 is (5 ± 0,1) mA. The normal frequency range power meter from 45 to 500 Hz, the operating frequency range - 500-1000 Hz.
The limit of additional error D5089 appliance power meter, 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 D5089 appliance power meter, frequency deviation caused by the upper limit of the normal region 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 D5089 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, if the front of the device otherwise stated meaning.
Changing the Power meter readings D5089 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 the value of the measuring range at a 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 D5089 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.
Overall dimensions not more than (205 ± 1,45) x (290 ± 1,6) x (135 ± 2,0) mm, weight of the unit is not more than 4.3 kg. Overall dimensions of the transformer housing no more than 65h85h45 mm, weight of the transformer is not more than 0.5 kg.
