2. When testing an SE or SAO with the output voltages shown in the
What is the approximate DC output voltage of an SET-3@
Current Converter?
Use the voltages in the following chart as a guide.
Can the SE be used for single-phase applications?
Yes it can, but the open-phase element cannot be used. Turn
OFF the open-phase setting on the function setting DIP
switch. Refer to the Q&A section on the SAO Current Sensor
for the overcurrent setting method. Consider using an SAO-
@S Current Sensor (for single-phase).
What will happen if a control power supply with an
automatic reset is taken from the same circuit as the
motor circuit?
The allowable fluctuation range for a control power supply
with an automatic reset is 85% to 110%. An open phase in
the motor circuit power supply will reduce the voltage to up to
50%. Thus, a power supply with an automatic reset will not
be able to operate.
