The electronic controller of the current (ECT) produces a signal upon the occurrence of one of the following events: – short circuit – electrical idle (during the dry) – electrical current exceeds the rated – exceeds electrical current above the maximum allowed – failure of one or two phases – phase imbalance of current – low insulation resistance (500kOm 10% for the modification of M2, M4, M5, M8). Optional: interface with PCs, digital input, contact pre-start or alarm. Model Range POS-5 from 0,2 to 50 A, POS-10 from 0,8 to 100A POS-25 from 1,6 to 250 A POS-60 from 3 to 600 A POS-125 6 to 1250 A pos 250 from 10 to 2500 A POS-625 from 30 to 6250 and the controller works in conjunction with a control panel CP-05, which provides data read and adjust settings of the controller. Controllers POS-5-M and ACT-10-MX may use current transformers with rated currents of the secondary winding 5A. ooo SibElektroZaschita " developed and started production of products ektm which food is carried out as a variable voltage (50 420 V frequency 45 Hz 5 ) and permanent (50 600 V) voltage without the need for additional resistors (As in scr-3 and EKRM-3) and without additional switching supply leads.
