Table 3-2 Component Name (Rear)

Name
Used when controlling the voltage value setting
by the external signal (VCA), when
synchronizing the output frequency with the
external signal (SYNC), and when outputting the
amplified external signal (EXT, ADD).
Can observe waveforms of the output voltage and
output current when connected to a unit such as
oscilloscopes.
A System Cable can be connected to make
multiple models into a polyphase output system.
Used to control this product externally by logic
signal and non voltage contact. Also it can obtain
the state of this product with a logic signal.
It is connected CONTROL IN connector (No.17)
with the attached control cable (25 pin) when
using DIP or RIN.
GPIB or LAN communication interface.
Either one can be chosen when ordering.
RS232 communication interface.
USB communication interface.
Air outlet for exhausting the heat.
Power input terminal.
Covers the power input terminal.
Output terminal.
Connect to the load end that is located in the
distance from the main unit to detect its voltage.
Covers the output terminal and the sensing input
terminal. When no load is connected, attach the
cover so that the cutout of the cover comes on the
upside.
Output sync signal in quick change operation and
fluctuation test.
It is used as trigger signal to record waveform.
Output sync signal in quick change operation. It
is connected to quick change sync input
connector on DIP.
It is connected to CONTROL SIGNAL connector
on DIP or RIN.
It is connected CONTROL I/O connector (No.4)
with the attached control cable (25 pin) when
using DIP or RIN.
