LVT

בקר פאזה מתח תלת פאזי
Monitors its own supply voltage
Detects Phase failure and Phase sequence
Detects asymmetry rates from 10% – 20% of UN
Minimum and maximum threshold can be adjusted between -20% / +20%
Not effected by harmonic distortion
Detects Loss of one / two phase
Detects loss of neutral
Detects Phase failure with regenerated voltage present (Back EMF)
Fixed hysteresis
Time delay on recovery, can be adjusted between 0.1 to 10 seconds
LED indicates for: relay status, asymmetry, sequence, over voltage and under voltage
