Functioning
Relay is designed to work with current transformer with secondary current 5A. Primary circuit of transformer is connected in the mea-sured current circuit and the secondary to the relay measuring contacts. Relay work with one of four work functions. You can select function by potentiometer FUN, and set the selected function [A, B, C or D]. By potentiometers you can set current threshold – by lower Imin and by top Imax. Above the measured current makes closes the appro-priate contacts, accordance in the selected work function. Contact is close with delay set by potentiometer T1 (to contact R1) and T2 (to contact R2). Close the contacts is signalling by shining a appropriate LED Imax and Imin.
Current relay EPP-620
4-functions.
Current relay is used to control the value of the current in the circuit measured with switch contacts function in the case of the value of current above the set threshold values.
