Phase sequence sensor 230/400V AC type CKM-01 EXT10000019

The CKM01 phase sequence sensor is used to protect devices powered from a three-phase network (e.g. motors) against damage, in the event of a phase voltage failure, phase voltage asymmetry or wrong phase sequence.
The threshold value of the activation voltage can be set by the user using a potentiometer .
The system does not protect against symmetrical voltage drop. The system is powered from the L1 phase.
Off delay and voltage hysteresis make the system resistant to short-term voltage fluctuations.q
