Monitoring of local generator sets and voltage supplies
For precise frequency measuring with fast response time
High disturbance immunity
Separately adjustable trip points and separate outputs for over-
and under frequency (1 or 2 c/o each)
MK 9143N / MH 9143:
Trip points adjustable precisely and reproducible on 10 step rotational switch in the range of ± 0,1 Hz to ± 5 Hz related to 50 or 60 Hz
Nominal frequency 50 or 60 Hz selectable
Fixed hysteresis optimised for trip point
As option one common output for under and over frequency “Window”-mode (MK 9143N/400 / MH 9143/400)
Variable alarm value in the range of 45 to 65 Hz
Hysteresis adjustable for under- and over frequency separatelyadjustable 0 …20% Common output for under and over frequency “Window”-mode can be selected
Start up delay 0…30 s selectable
Manual or auto reset selectable
Output relay energized or de-energized on trip selectable for
over frequency
Output relay de-energized on trip for under frequency
Universal frequency measuring input for AC 40 … 550V
Several options for auxiliary supply
LED indicators for auxiliary supply, input frequency, over and
under frequency alarm
