is high. In high range, the rated output current is half of the rated output current in low range. (Refer
to specifications in section 2.2). Switching between high and low range dose not have any influence
to the voltage setup. However, when in output mode, switching between high and low ranges will
cause an instant power off for minimum 20mS. Improper switching will not be accepted by the
CPU, such as 300V as low range.
3.3.5 Current Limit Setup
In standby mode or output mode, press ASET button to go to current limit setup mode. Press key
“
︿
” or “
﹀
” once to display the last preset current limit value. Press “
︿
” or “
﹀
” once more to
adjust the current limit value.
If there is no any operation to set the current limit value within 2 seconds, it will automatically
return to the last preset current limit value.
When the output current exceeds the preset current limit value, the output will be shut off and the
OUTPUT/RESET LED indicator will blink.
3.3.6 P/PF Operation Key
Press key P/PF at any time to switch the display for power and power factor.
3.3.7 OUTPUT/RESET Key
The OUTPUT/RESET key can turn on or off the output. The OUTPUT/RESET LED indicator
lights on when the output is ON. When there is abnormal output, the output will be automatically
turned off and the OUTPUT/RESET LED indicator will blink. The beeper alarms at the same time.
Press this button once to turn off the beeper. Press it twice to reset the output. Press it for the third
time to restart output.
3.3.8 Memory Key
The AC power supply has 3 memory groups for panel setting save & recall – M1, M2 and M3. The
panel setting can be stored to any one of the memory groups and be recalled from this memory
group. After finish panel setting, press the memory key M1, M2 or M3 for at least 1 second, the
panel settings will be stored to the selected memory group. To recall the stored panel setting, press
the memory key M1, M2 or M3 once.
3.3.9 System Setup
Press key SYSTEM to go to the system setup mode. In this mode, the BPS LED indicator lights on.
The system parameters are displayed on voltmeter and frequency meter. Press key “
︿
” or “
﹀
” to
select system parameters.
Press key “
︿
”to the baud rate setup and cycle the parameters as: 4.8, 9.6, 19.2 and the ADDR LED
indicator lights. And the parameters are display on voltmeter and frequency meter.
