INSTRUCTION MANUAL
2-2. CN01, CN02 Connector pin configuration and Function
CN01, CN02 pin configuration and function are the same.
They are connected to each other in this power supply unit.
When the pin of CN01 side is shorted the same function pins of CN02 side are shorted.
Please note that the function cannot be separately set with CN01 and CN02.
Pin No. Configuration Function
1 ＋
V
Connected to ＋ Output terminal in this Power supply unit.
(+V terminal can not supply load current.)
2
＋ S
Remote sensing terminal for + output
(For remote sensing function, which compensates for line drop between power supply terminals and load
terminals. Connect to +V terminal when remote sensing function is unnecessary)
3 －
V
Connected to
－
Output terminal in this Power supply unit.
(-V terminal can not supply load current)
4 －
S
Remote sensing terminal for - output
(For remote sensing function, which compensates for line drop between power supply terminals and load
terminals. Connect to -V terminal when remote sensing function is unnecessary)
5 PC
Current balance terminal
(For output current balancing in parallel operation.)
6 COM
Ground for PC and PV signal
.
7 PV
Output voltage external control terminal
(For power supply output voltage control with an external voltage. Connect it with the terminal REF when
PV function is unnecessary. )
8 REF
Reference Voltage terminal for Output voltage control
(REF and PV are connected when shipping.)
9 CNT
Remote ON/OFF control terminal
(When the CNT is pulled to TTL low, the power supply turns on.)
10 TOG
Ground for CNT and PF signal.
11 PF
Power fail signal output terminal.
(As the output voltage drops, FAN stops and AC input voltage down, open collector output, “Power Fail”
signal will output “High”.)
12 TOG
Ground for CNT and PF signal.
CN01
、 CN02 are connected in this power supply unit as follows.
CN01
１ ３ ５ ７ ９ １１
２ ４ ６ ８ １０ １２
CN02
１ ３ ５ ７ ９ １１
２ ４ ６ ８ １０ １２
