Specifications V3-12-B
FUNCTION
In the model A, the device monitors the
correct phase sequence L1, L2, L3 on
the pins 4, 6, 8, and it detects the
phase failure if the back voltage
generated by the motor is lower than
85% of the nominal voltage.
In the model B, the device monitors the
correct phase sequence.
Features V3-12-B
INPUTS
Input Resistance = 2 MΩ
4, 6, 8 (V max 750V)
On the inputs 6 and 8 the capacitors
“X2”, have been applied, so that it is
not necessary to apply the protection
fuses (EN 60335-1)
OUTPUT: see Fig.1 e Fig 2 or TAB A.
