3. Operation
3.1. Controls and description
0
1. Slave constant-current indicator or two-ways parallel state indication: the LED illuminates
when the slave output is in current-regulated state or the two adjustable outputs is in parallel.
0
2. Slave constant current adjustment: adjusting slave output current value (adjusting the
current-limit protection point).
0
3. Slave constant-voltage indicator: the LED illuminates when the slave output is in voltage-
regulated state.
0
4. Slave constant voltage adjustment: adjusting slave output voltage.
0
5. Amp display: indicating slave output current by analog meter or LCD.
0
6. Volt display: indicating slave output voltage by analog meter or LCD.
0
7. Control switch: for selecting the two adjustable outputs independent, series, parallel.
0
8. Amp display: indicating master output current by analog meter or LCD.
0
9 Control switch: for selecting the two adjustable outputs independent, series, parallel.
10. Volt display: indicating master output voltage by analog meter or LCD.
11. Master constant-current indicator: the LED illuminates when the master output is in current-
regulated state.
12. Mater constant-voltage indicator: the LED illuminates when the master output is in voltage-
regulated state.
13. Power switch: the unit is "ON" when this button switch is depressed, while CV LED (3) (12)
or CC LED (1) (11) illuminating.
14. Master constant voltage adjustment: adjusting master output voltage.
15. Fixed 5V output Terminal (+): connecting the positive terminal of load.
16. Fixed 5V output Terminal (-): connecting the negative terminal of load.
17. Master constant current adjustment: adjusting master output current value (adjusting the
current-limit protection point).
18. Master output Terminal (+): connecting the positive terminal load.
19. Case ground: connecting the case to ground.
20. Master output terminal (-): connecting the negative terminal of load.
21. Slave output terminal (+): connecting the positive terminal of load.
22. Case ground: connecting the case to ground.
23. Slave output terminal (-): connecting the negative terminal of load.
24. Output-switch: output voltage ON/OFF
