SET-3A Omron, SET-3A Datasheet - Page 12

• Manufacturer Part Number: SET-3A
• Description: CONVERTER CURRENT 1-80A FOR SAO
• Manufacturer: Omron
• Series: SAOr

Specifications of SET-3A

• Accessory Type: Current Converter
• For Use With/related Products: SAO Series
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant
• Other names: SET3A

Connection Procedure
Run the primary wires through any two of the three holes on the SET-
3 the number of times specified for the SET-3@.
Setting Procedure
The operating value will change when single phase is used as in the
figure above. Therefore, the setting must be changed.
Make the setting to approximately 0.77 times the current at which
operation is desired. For example, for operation at 10 A, set the value
to the following:
10 x 0.77 = 7.7 A
In any case, the SAO is adjusted for three-phase use. As a
precautionary measure, therefore, perform confirmation testing using
the actual load.
Q
Motor
What is the procedure for using the SAO with a single
phase?
The following describes the single-phase operating
procedure for the SAO. Models for single-phase circuits,
however, are also available. Refer to SAO-

Can two SAO Current Sensors be used connected to one
SET-3@? If not, can a diode or other device be inserted?
It is not possible to connect two SAO Current Sensors to one
SET-3@. The SET-3 output is designed so that the output
voltage will match when one SAO (SE) is used.
Operation is not possible even with a diode inserted.
Operation as shown in figure 2, however, is possible if the
capacity of the CT is sufficient.
