Electronic controllers of a rastsepitel of EKR-1,EKR-2 are intended for continuous control of current in three-phase power lines of alternating current of the industrial frequency of 50 Hz of 220/380 V and protective shutdown of loading at emergence emergency operation.
The operating contact of the EKR1 controller works for disconnection of a chain at an emergency shutdown.
The operating contact of the EKR2 controller can work both for disconnection, and for short circuit of contact of management at an emergency shutdown (the mode is set by the consumer).
Controllers provide four-level adjustable protection on current on three phases of a network:
- on the level of the minimum loading Imin - with an adjustable delay of operation of Tmin from 1 to 250 sec.;
- on Inom overload current level - with an adjustable delay of operation of Tnom from 1 to 250 sec.;
- on the level of current of the maximum protection Imax - with an adjustable delay of operation Ttakh from 1 to 250 sec.;
- on level over Iotc-current with an unregulated delay of operation no more than 0,05 sec.
Controllers are manufactured six face values on diapazo controlled currents from 2 to 5000 And. At connection via current transformers range can be expanded to 100 KA.
Controllers provide registration of date, time, controlled currents and a cause of accident at the time of an emergency shutdown.
The EKR1 controller keeps in memory parameters of four last on time of emergency shutdowns.
The EKR2 controller keeps in memory parameters of eight last on time of emergency shutdowns.
The EKR1 controller incorporates the programmable timer providing a possibility of automatic connection / shutdown of loading according to the set program in real time. Number of the programmable cycles "inclusion shutdown" in a techeniyesutok - from 1 to 10, permission on time of 1 min.
The EKR2 controller of the timer has no.
Power supply of controllers is carried out from one phase of the alternating current main of 220/380 V by the frequency (50±2) Hz. The controller keeps working capacity at decrease in the feeding tension on 25 from nominal lasting no more than 5 sec.
Controllers are intended for work together with the control panel and indications of PU-04 which joins in komplektpostavka according to the additional requirement of the customer and is paid separately. One panel can serve any number of controllers.
