1) Utilizes SMT technology.

2) LCD display to show voltage and current.

3) LCD display to show regulated voltage and current.

4) Green/Amber LCD back-light selectable.

5) Auto interchangeable of regulated voltage and current.

6) Multi-turn variable device to provide high precision voltage

setting.

7) Step-by-step current limit setting.

8) Auto-tracking on PARALLEL and SERIAL working condition.

9) Extended output terminal connection.

10) Continuously working under full loaded condition.

9. OPERATION PROCEDURES

– DUAL TYPE

9.1   Constant Voltage Setting Method

1) Turn on power switch.

2) Adjust voltage setting knob to the desired voltage which can be

shown in the LCD display.

3) Connect the load, make sure the load current not exceeding the

maximum output current.

9.2 Constant Current Adjustment Method

1.Adjust by turning the voltage setting knob to desired voltage.

2. Press the CV/CC setting button down to light up the CC/CV setting

indicator.

3. Use a wire to shorten the (+) and (-) terminal at output terminal.

4. Push the UP or DOWN button to obtain the current value.

5. When  pushing  and  hold  the  UP  or  DOWN  button  over  0.8  sec,  the

value will go up or go down continuously.

6. Release the shortend wire, connect the load to begin operation.

7. The setting of current value will be stored in the EEPROM after off.

8. The current value will be resumed by pushing the CV/CC button

when next power on.
