Motor
Compressors cannot operate correctly under conditions such as
under voltage, asymmetry voltage, phase loss, or phase
sequence. The K8AB-PM can be used to monitor 3-phase
voltage, the phase sequence, and phase loss.
A single K8AB-PM can monitor over voltage, under voltage, the
phase sequence and phase loss in 3-phase voltage. It can also
output individual alarms for over voltage or under voltage using an
SPDT relay. The K8AB-PM is able to recognize which alarm has
occurred.
The 61F-D21T-V1 can be used to control the liquid level in a tank.
Fixed type
Because the sensitivity resistance can be adjusted from 10 to 100 kW, there is
no need to change models to match different liquid types and concentrations.
You can also set the operation time in a range of 0.1 to 10 seconds to prevent
operating errors due to chattering.
Water supply and draining control can be changed by DIP switch.

Power grid panel
The K8AB-PW monitors the voltage of power generated by a
generator. It also detects over voltage and under voltage in power
from a generator.
A single K8AB-PW can monitor 3-phase voltage. It can also
output individual alarms for over voltage and under voltage using
SPDT relays because it features two outputs with SPDT relays.
The voltage measurement range can be switched from 200 to 480
VAC and the K8AB-PW can be switched to monitor phase voltage
or line voltage.

Advantages
The K8AB-PW detects over voltage and under
voltage in power generated by a wind-powered
generator.
A single K8AB-PW can be used for a 3-phase power
supply with 3 or 4 wires. It can be used to individually
set and output over voltage and under voltage
alarms.
