2. Always keep good ventilation at the rear of the power supply, and do not use the power supply where a temperature exceeds 45°C.
3. Before turning the power supply ON, remove all connected loads and set the Voltage Adjustment Knob to the full counter-clockwise position (0V DC output).
4. To operate the power supply as a constant current supply, the current output should be set between 10% and 100% of the rated value (5A). The Current Limiting Indicator will light when the current limiting circuit is activated.
5. Use the Current and Voltage Adjustment Knobs for setting variable Current and Voltage output signals respectively. Use Variable Output Terminals for connections.
6. For 5VDC/3A output, use the Fixed Output Terminals.
7. The digital displays will indicate actual current and voltage outputs for each channel.
Keep the meter's cooling vents (rear & sides) clear of obstacles to prevent overheating.
9. Make sure good and tight connection between terminals and loads.
10. Constant Voltage Mode (each channel setup independently)
a. Disconnect any load from terminals and turn the Voltage Adjustment Knob to the end of CCW (0 VDC).
b. Check that the AC cable and source are good and correct.
c. Press the Power Switch ON. The LED windows will be light up which indicating that the power supply is in the operation state.
d. Turn the Current Adjustment Knob to the fully CW position.
e. Turn the Voltage Adjustment Knob to obtain a desired voltage.
f. Connect the load to the output terminals. The output terminals are floated from ground. Either one can be grounded as required.
g. If an overloading or short circuit occurred at the output terminals, the maximum over current will be the rated current with output voltage drops. The power supply will be automatically reverted to its normal operation once the external overloading or short circuit removed.
11. Constant Current Mode (each channel setup independently)
a. Disconnect any load from terminals.
b. Check that the AC cable and source are good and correct.
c. Press the Power Switch ON. The LED windows will be light up which indicating that the power supply is in the operation state.
d. Adjust the voltage to a value between 3 ~ 10 V range.
e. Turn the Current Adjustment Knob to CCW fully (Zero).
f. Short the output terminals between positive and negative.
g. Adjust the current CW to a required value by monitoring the current LED window.
h. Remove the jumper lead.
i. Adjust the voltage to a required value between 0 ~ 30 V.
j. Check the CC mode by shorting output terminals again by monitoring the current LED window.
