Wiring Diagram:
- VO+: Output positive
- VO-: Output negative
- +IN: Input positive
- -IN: Input negative
- CV: Output voltage adjustment
- CC: Output current adjustment
- EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
- When input and output is common grounded, no-load CV output constant voltage, CC output constant current
