4. Advanced Operation
2. In the [Ext Control] item, select [3: DevCtrl].
 Connection of DIP or RIN
Connect between the input terminal of DIP or RIN and the output terminal of this product. For detail
of connection refer to the instruction manual of DIP or RIN.
If the voltage drop due to wiring to DIP or RIN is large, it is possible to compensate the voltage drop
by setting Remote sensing to on with using AGC / auto-cal function or setting Remote sensing to FB.
(See 4.11)
In their case, connect between the FEEDBACK connector of DIP or RIN and the sensing input
terminal of this product with the feedback cable included in DIP or RIN. (See 8.2)

Synchronizing the Output Frequency with the Power Line or

the External Signal

When you select SYNC for the signal source, you can synchronize the frequency of the internal
signal source with the power line or the external signal. The icon
internal signal source is synchronized with the external signal. The icon
the synchronization is not performed. The measured synchronization frequency value is displayed in
the measured value area on the screen. See 11.11 for the measurement specification of the
synchronization frequency and 11.22.1 for the interface specification of the external
synchronization signal.
-------- Notes ------------------------------------------------------------------------------------------------------------
 The output on phase/off phase setting (3.4.7) is valid in SYNC also.
 You cannot make the output on if synchronization is not performed.
 When the switching from AC-SYNC or ACDC-SYNC mode to DC mode, the signal source is
forcibly set to INT.
