1. Bright LED display shows settings or actual level of output.
2. The independent CH3 output offers three commonly used voltage settings: 2.5,
3.3V, 5V.
3. C.V. / C.C. modes are clearly indicated in different colors.
4. Smart cooling fan control offers a well-balanced cooling mechanism, ensuring
quiet operation.
5. The tracking series and parallel mod can be selected with a single touch.
6. Indicators embedded in the keys provide an instant view of the power supply
status; the Key Lock feature prevents improper operation.
