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)
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)
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. )
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 .)
Connected to +Output terminal in this Power supply unit.
(+V terminal can not supply load current.)
Connected to -Output terminal in this Power supply unit.
(-V terminal can not supply load current)
Ground for PC and PV signal.
Ground for CNT and PF signal.
Ground for CNT and PF signal.
Current balance terminal
(For output current balancing in parallel operation.)
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.)

※Output ON/OFF control circuit and the Power fail signal circuit are
insulated with other circuits in the power supply.
(Insulating voltage AC100V)
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.
CN01、CN02 are connected in this power supply unit as follows.
