RKN-63
Purpose
The block of the relay of control of tension of RKN-63 is intended for protection of single-phase loading against inadmissible fluctuations of supply voltage.
RKN-63 provides shutdown of single-phase consumers at tension deviation limits of the admission established by the user, and automatic inclusion at normalization of tension.
Design of system
– The RKN-63 block is executed in the case for installation on a DIN lath.
– On the forward panel of the block there are 3 handles of regulation of parameters of the block and Network and Accident indicators.
– In the lower part of the block there are terminal blocks for connection of the block to a network and to the scheme of management.
– Adjustable settings are established by the user depending on parameters of the connected equipment.
