5.1 SETTING THE OUTPUT VOLTAGE
1 Connect the power supply to the power source.
2. Press the POWER SWITCH [1] to “I” position to turn on the power supply.
3. The CV INDICATOR [5] and POWER INDICATOR [3]* will on and the voltage value will be
displayed on the display.
4. Use the VOLTAGE COARSE TUNE KNOB [8] and VOLTAGE FINE TUNE KNOB [9] to adjust and
fine turn the voltage to give a desired output voltage.
5. Connect the circuit to the MAIN TERMINAL [12, 14].
6. When the CC INDICATOR [4] is on, adjust the CURRENT COARSE TUNE KNOB [10] and
CURRENT FINE TUNE KNOB [11] to give a suitable current.
Caution:
zMake sure the INPUT VOLTAGE SELECTOR [19] set to a correct position. Otherwise, it will
damage the power supply.

7. TROUBLESHOOTING
Problem Solution
The power supply cannot start
up, no display
1. Ensure the power source or power cord is working properly
2. Check the fuse. If the fuse broken, disconnect from the power
source then replace with identical rating fuse.
When operate in CV mode, the
voltage drop down and the CC
indicator on
It is the current protect. The desired current range is under the circuit
gain. The power supply switched to CC mode. Adjust the current knob
clockwise to increase the range.
The power supply output
unstable
1. The power supply needs at least 30 minutes to warm up and
reach the specification.
2. The power source voltage is under the minimum requirement.
If the above solution cannot solve the problem, please contact the local reseller.
