Parameters:

Input voltage: DC 5V-27V (Input voltage should be 2V higher than output voltage)

Output voltage: DC 1-24V

Output current: 3A max. Recommend to use within 2.5A

Output power: lower than 30W

Voltage resolution: 0.01V

Voltage precision: defaulted ±0.1V (can be adjusted manually)

Current resolution: 0.001A

Current measurement range: 0-3A

Current precision: defaulted ±0.05A

When output current lower smaller than 0.05A, the display error will be large; small current of 10-40mA are not be able to be displayed.

Capacity resolution: 0.001Ah

Capacity measurement range: 99.99Ah

Conversion Efficiency: < 95%

Working current: 30mA

Dimension: 55x73.5x27mm

Features:

PARAMETER --- input voltage range DC 5V-27V; output voltage range 1-24V; output current 3A max, recommend within 2.5A; output power 30W max.

PROTECTION --- reverse connection protection; anti-backflow protection; over-current protection.

DISPLAY --- clear LCD screen displays input voltage, output voltage, output current, power, capacity (switch by button).

FEATURES --- with buttons to calibrate accuracy, switch display parameter and control output; with potentiometer knob to adjust CC & CV; with indicators to indicate output status and charging status.

NOTE:

1). The USB output voltage value is the same as the terminal block output voltage value instead of 5V fixed, please check the output voltage before connecting any USB device.

2). The case is packaged un-assembled to avoid damage during transit. It needs to be assembled manually. 

3). If the output voltage cannot be adjusted, please rotate the CV potentiometer anti-clockwise for 20 laps and try again.
