ЕС3020 Frequency counter ES3020.


It is possible effectively delivery of any quantity.
Frequency ES3020 (EC 3020, EC-3020, ec3020, ES3020, ES 3020, ES-3020, ЄS3020, ЄS 3020 ЄS-3020, ec 3020, ec-3020)
Frequency ES3020 is designed to measure the frequency of the alternating current to power plants and substations and transmission of its values ​​on the interface RS485.
Connects directly to the ITN, and measures the rms voltage at its secondary.
Frequency ES3020 has the ability to install the interface to the N and setting the upper and lower permissible values ​​of the measured frequency.
Indicates the current value of the measured voltages, taking into account the set K N and the dimension of the measured values ​​of the frequency "Hz."The number of digits - five decimal places.
Frequency indicates the flashing of the ES3020 «min» or «max» out of the measured frequency of the boundary set setting, with a closed output contact appropriate relay.
Designed for use in stationary conditions, macro-regions with a temperate climate with temperatures ranging from 5 º C to 40 C and 90% relative humidity at 25 ° C.
