PROGRAMMABLE AC POWER SOURCE 30
Table 3-2 Component Name (Rear)
No. Name Description Refer to
1 External signal input
connector 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). 4.17,
4.19,
4.20
2 Monitor output connector Can observe waveforms of the output voltage
and output current when connected to a unit
such as oscilloscopes. 4.10
3 SYSTEM I/O connector Not used. -
4 CONTROL I/O connector 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.

5 GPIB connector
or
LAN connector
GPIB or LAN communication interface.
Either one can be chosen when ordering.
6.1.3,
6.1.4
6 RS232 connector RS232 communication interface. 6.1.2
7 USB connector USB communication interface. 6.1.1
8 Air outlet Air outlet for exhausting the heat. 2.2
9 Power input terminal Power input terminal. Power input is 1P2W or
3P3W or 3P4W, either of which can be chosen
when ordering. (The power input 1P2W is not
selectable for DP180LM.) Figure 3-2 shows the
case of power input 3P3W. 2.4
10 Polyphase output terminal Output terminal for the single-phase three-wire
and three-phase four-wire. 2.5
11 Single-phase output terminal Output terminal for the single-phase two-wire. 2.5
12 Sensing input terminal Connect to the load end that is located in the
distance from the main unit to detect its
voltage. Common among the single-phase
two-wire, single-phase three-wire, and
three-phase four-wire output. 4.11
13 Resin-molded cover Covers the power input terminal, the sensing
input terminal, the single-phase output terminal
and the polyphase output terminal. When no
load is connected, attach the cover so that the
cutout of the cover comes on the upside. 2.4,
2.5
14 Status output connector Output sync signal in quick change operation
and fluctuation test.
It is used as trigger signal to record waveform.
4.18.1,
