PHASE SEQUENCE SENSOR 230/400V AC TYPE: CKM-01
Product Description
The CKM-01 phase sequence sensor
device is used to protect devices powered
from a three-phase installation (e.g.
a motor) from being damage in case of
phase voltage switch off. It is because of
phase voltage asymmetry or wrong phase
sequence. The threshold switch on value
is can be adjusted by the user by means
of a potentiometer. The system does not
protect from symmetrical voltage drop and
it is powered from L1 phase. The switch
off delay and voltage hysteresis cause the
system is resistant to momentary voltage
changes.
