ON/0FF: Output control key

S1: Mode select key / memory key

Size: 47 x 41 x 16mm (L x W x H)

Weight: 25g

Input voltage: DC 5-25V

LED Indicator: YES

Output voltage: DC 0.5-25V(Adjustable)

Continuous output current:2A(max)

Continuous input current:2A(max)

Input / output power:25W(max)

Input / output current:The input / output current (Uin*Iin* efficiency =Uout*Iout) under rated conditions is calculated according to the conservation of power


1. The input and output voltage can be alternately displayed.

2. Boot status can be defined freely.

3. With button switch machine function, easy to control the output.

4. High power MOS tube reverse connection protection circuit, improve work efficiency and reliability.

Work pattern description:

Input voltage mode: Boot default to input voltage mode, show * *.*LED indicator light, output closed.

Output voltage mode: Press S1 to switch to the output voltage mode once, indicating that the **.*LED indicator goes out,If output is off, display 0FF.

Alternate mode: Press the S1 input / output voltage alternately again, and the 3S turns to displayData (again, revert to the input voltage display mode)

Memory model:

Long press the S1 key above 2S, the module automatically remembers the current working state as the default boot state.

The [0] stands for default to show the input voltage

The [1] stands for the default boot to display the output voltage

[2] represents the default boot / input / output voltage alternation display
