Wattmeter D539 (D-539, D 539)
 
D539 Power Meter is designed to measure active power in AC circuits frequency from 45Hz to 65Hz, as well as in the extended frequency range from 65Hz to 500Hz, inclusive, and in DC.
Wattmeters can also be used for measurement in AC circuits in the frequency range from 500Hz to 1500Hz, inclusive, with the main error of devices normally not exceed ± 2,5% of full scale of the working part of the scale;
A distinctive feature of the device is its own small power consumption.
 
Technical characteristics of the devices wattmeters D539:
