Remark:
a)
The ambient temperature of “Permissible Current” is at
40
℃
, the withstanding temperature of conductor is at
105
℃
according to the condition of the distributed
single wire.
b)
The permissible current listed as above is suggested to
be used under 70%.
c)
When the current value exceeds above suggestive list,
can select more wires used in parallel according to
above list.

3. OPERATION
Voltage Setting:
Voltage setting contents “110V”, “220V”, “
▲
” and “
▼
” four
keys.
a.
When any one of the keys mentioned above is pressed, the
voltage display will flash one time, the unit will go to the
setting mode and show the voltage setting value.
b.
If the “110V” Key is pressed, the output voltage will be
adjusted to 110V immediately. Meanwhile, the voltage
display will switch back to the reading mode automatically.
c.
If the “220V” key is pressed for 0.2 seconds continuously
(for safety reason, must be), the output voltage will be
adjusted to 220V. Meanwhile, the voltage display will switch
back to the reading mode automatically.
Note: It will not work if the output voltage is setting on
low range (0~150V output)
d.
If either “
▲
” or “
▼
” key is pressed for 0.5 seconds, the
output voltage will be adjusted. If either “
▲
” or “
▼
” is
pressed twice, the output voltage will be adjusted
immediately.
e.
The adjusting rates are 0.1V/step on fine adjust mode and
1V/step on coarse adjust mode.
f.
The first six steps of adjustment will be spent 0.25 seconds
per step. If the key “
▲
” or “
▼
” is pressed continuously, it
will spend 0.13 second per step for the rest steps. If the key
is released, the voltage adjustment would be stopped and go
back to the original adjustment speed (0.25 seconds per step)
automatically.
g.
If the output mode is setting ON (the indicator “OUTPUT”
would light), the output voltage could follow the setting
voltage simultaneously.
