Note:
Do not connect a load to the DC output monitor pins
(+V or –V).
Fig.12
Parallel operation
When the CB pin (pin 5 on CN) and the CBG pin (pin 6 on CN) are connected, the current balance function operates and
parallel operation is possible.
Up to 5 Units can be connected.
Notes:
1. Use 2-conductor shielded cable as connection wire ( 6).
2. Adjust the output voltage of each power supply to the same value within 1% or 100 mV, whichever is smaller.During
parallel operation, it is possible that the load current will flow excessively to either power supply and damage internal
components.
3. Parallel operation is used to increase static capacity. Output voltage may drop with sudden load fluctuations.
4. There may be steps in the rising waveform of the output voltage during parallel operation.
5. Remove the standard supplied connector and prepare a connector separately.
6. When N units are connected, a rush current equal to xN the current of one unit will flow.
Fig.13
Check the characteristics of the external fuse or breaker and select appropriately so that the fuse does not blow or the

Remote Sensing Function
This function is used to compensate for voltage drops on the load lines.Connect the +S pin (pin 2 on CN) to the positive
load terminal and the –S pin (pin 4 on CN) to the negative load terminal to enable remote sensing.
When not using the remote sensing function, use the standard connector. The + S and +V pins (pin 1 on CN) and the – S
and – V pins (pin 3 on CN) will be connected.
Notes:
1. Use 2-conductor shielded cable as connection wire ( 7).
2 .Use as thick a wire as possible since high voltage drops on the load lines ( 8) may activate the overvoltage protection
function.
3. The total line voltage drop (+ side line and – side line) must be less than 0.3 V.
4. If the sensing line is too long, it is necessary to put an electrolytic capacitor across the load terminals. Please take note
that the electrolytic capacitor may generate heat due to the ripple current, depending on connected load. Therefore, the
Fig.14
electrolytic capacitor must have a ripple current allowance higher then the output ripple current.
5. The stability and accuracy of the output will deteriorate if the +S or – S pins are open.
Always connect the +S and –S pins.
6. Remove the standard supplied connector and prepare a connector separately.
7. Make sure the remote sensing pins (+S, –S) are not open.
Remote Control Function
This function turns outputs ON and OFF using an external signal while input voltage is applied, using the +RC pin (pin 7 on
CN) and the –RC pin (pin 8 on CN). Connect a switch or transistor to the +RC and –RC pins to use the remote control
function.
When not using this function, the +RC and –RC pins are shorted by using the standard connector.
The Maximum input voltage: 12V max.
Fig.15
The Maximum allowable reverse voltage: –1V max. Sink Current: 3.5mA
Notes:
1. Use 2-conductor shielded cable or twisted-pair cable as connection wire.
2 V
:
0.1 mA
2. The remote control circuit is isolated from the input and output circuits of the power supply.
3. Remove the standard supplied connector and prepare a connector separately.
(
:
)
4. If a reverse voltage is applied to the remote control pin, output voltage ON/OFF will not be possible. Exercise caution
when wiring.
Alarm output function
The Power failure alarm indicator will light red to indicate an output voltage error if overload, overvoltage, or overheat
protection is activated, if a drop in the input voltage causes the output voltage to drop, if the built-in fan motor stops, and
Fig.16
during remote control standby. The alarm is also output externally by a transistor.
Transistor output: 30 VDC max., 50 mA max. Residual voltage when ON: 2 V max, leakage current when OFF: 0.1 mA
max.
16
Alarm detection voltage: Approx. 80% of output voltage setting The transistor output is turned OFF if an alarm is detected
(no power to pins 11 and 12 on CN), and the LED indicator is lit (
Notes:
1. This function monitors the voltage at the power supply output terminals. To check actual voltage, measure the voltage on
the load side.
2.Remove the standard supplied connector and prepare a connector separately.
Peak Output Current
(S8JX-P30024
See product catalogue for details.
Notes:
lp
1. Do not allow the peak load current to continue for more than 10 seconds, and do not allow the duty cycle to exceed the
conditions indicated in Fig. 16. This may damage the power supply.
lave
2. Lessen the load of the peak load current by adjusting the ambient temperature and the mounting orientation.
3. Ensure that the average current of one cycle of the peak current does not exceed the rating. This may damage the
power supply.

Signal I/O Connector Harness Manufacture Method
This product is using PHD connector made from JAPAN SOLDERLESS TERMINAL MFG CO LTD. Regarding to
(mm)
manufacture of a connector, it becomes the regulation as following.
1. Appricable Wire and Crimping tool
Appreciable wire per barrel size is UL1007 (standard wire ) and its equivalent standard wire can be used. Regarding the
0.70
1.7
AWG#22, use UL1061 or its equivalent standard wire, because wire insulation outer diameter of UL1061 is small. Wire
size is AWG#26 to AWG#22 and insulation outer dia is ø1.0 to ø1.5 mm.
0.75

Crimping tool is as below.
0.80

2. Crimping
The reference value of wire strip is 2.3mm. Addording to wire to be used, adjust dials of applicator to a proper crimp
height.

Notes:
1. Crimp height at wire barrel should be set to pre-determined dimensions.
Fig.19
2. Adjust crimp height at wire insulation barrel to the extent that wire insulation is slightly pressed, and set it so that
crimping is not excessivery.
3. Crimping condition at wire insulation barrel is as below
Check the tensile strength at crimped part when operation finishes.
Table of tensile strength at crimped part
Check of crimping appearance visually for correct crimping as referring to
3. Inserting contact into housing
(1) Hold contact with its lance part upland align contact lance guide at housing with contact lance, and then insert contact
parallel to insertion axis.
(2) Insert contact into housing without stopping to innermost. When contact is fully inserted into housing,housing lance
clicks and there is feeling of response.
(3) Check after inserting crimped contact into housing.
Check secure locking per each insertion by pulling wire softly with a force of approx. 1N
