CN01, CN02 Connector pin configuration and function
CN01, CN02 pin confi guration 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.

Connected to +Output terminal in this power supply unit.
(+V terminal can not supply load current.)
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.)
Connected to -Output terminal in this power supply unit.
(-V terminal can not supply load current.)
Remote sensing terminal for -0utput
(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.)
Current balance terminal
(For output current balancing in parallel operation.)
Ground for PC and PV signal.
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.)
Reference voltage terminal for Output voltage control
(REF and PV are connected when shipping.)
Remote ON/OFF control terminal
(When the CNT is pulled to TTL low, the power supply turns on.)
Ground for CNT and PF signal.
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 .)
Ground for CNT and PF signal.

CN01，CN02 are connected in this power supply unit as follows.
① ＋: ＋ Output terminal
② −: − Output terminal
③ ON: Output (Power On) indication green LED (The indicator turns on when the
power supply output is in normal operating condition.)
④ V.ADJ: Output voltage adjust trimmer (The output voltage rises when trimmer is
turned clockwise.)
⑤ CN01: Remote sensing, ON/OFF control signal, Current balance signal,
⑥ CN02: Output voltage external control signal and Power fail signal output connector.
⑦ N: AC input terminal N : Neutral line
⑧ L: AC input terminal L : Live Line (Fuse in line)
⑨ FG: Function Ground terminal (Frame ground)
