2. Terminal connecting method
·
Input must be off when making connections.
·
Connect FG terminal to ground terminal of the equipment.
·
Output current of each connector pin must be less than 7A. ( For connector type )
·
The output load line and input line shall be separated and twisted to improve noise sensitivity.
·
Remote ON/OFF control lines shall be twisted or use shielded wire.
·
Use the output connector specified in outline drawing. Also, use recommended crimping tool.

3. Explanation of Functions and Precautions
3-1. Input Voltage Range
Input voltage range is single phase 85 ~ 265VAC ( 47 ~
63Hz ) or 120 ~ 330VDC. Input voltage which is out of
specification may cause unit damage.
3-2. Output Voltage Range
V.ADJ trimmer on the front panel side can adjust the out-
put voltage of CH1 within the range. To turn the trimmer
clockwise, the output voltage will be increase. Output
voltage range is within 5 ~ 5.25V. Note over voltage pro-
tection ( OVP ) function may trigger if the output voltage
is increased excessively.
3-3. Inrush Current
This series has used Power Thermistor to protect the cir-
cuit from Inrush Current. Please carefully select input
switch and fuse in cases of the high temperature and re-
input the power.
Safety Earth :
For safety, Connect
tom of chassis to ground terminal of the equip-
ment. Screw must be used M4. on the bottom of
chassis.
3-4. WATTBOX
This series designed as a WATTBOX. You are flexibly
adjust output power of each channel within the limit of
the maximum total output power in specification.

3-5. Minimum output Current
The output voltage of all channel is stabilized when min-
imum output current of CH1 is more than 10% of maxi-
mum output current.
3-6. Over Voltage Protection ( OVP )
The OVP function ( Inverter shut down method, manual
reset type ) built into CH1 output only. When OVP of
CH1 channel triggers, the all outputs will be shut down.
The input shall be removed for a few minutes, and then
re-input for recovery of the output to recover. OVP set-
ting shall be fixed and not to be adjusted externally.
