## Description

**Function**- 
- Operating mode description
- 
- With key off function, and reduce power consumption.
- 
- Power state can be freely defined
- 
- Input and output voltages can be displayed alternately
- 
- On/0ff output status, high level means output off, low level means output on. (note: high level (3.3v), the maximum output current 5mA)
- 
- Output voltage mode:Boot default display it, LED indicator off
- 
- Input voltage mode:Press button switch to it , LED indicator on
- 
- Alternating mode:Press button again input/output voltage alternately display (3s). Press button again, switch to output voltage display

**Features:**

- 
- In+: Input positive
- 
- In-: Input negative
- 
- Out+: Output positive
- 
- Out-: Output negative
- 
- weight: 20g
- 
- Dimensions: 62 \*26 \*14mm(length\*width\*height)
- 
- Ripple peak: About 100mV
- 
- Display color: Red/Green/Blue
- 
- Input voltage: 4.5-28V
- 
- Output power: 15W maximum
- 
- Output voltage: 1.3v-25v (step-down mode, the input voltage must be 2v higher than the output voltage)
- 
- Output current: 1.5A
- 
- Ripple frequency: About 150KHZ
- 
- Voltage meter accuracy: ±(5 ‰ +1 digit)
- 
- Static power consumption: Typical about 20mA
- 

 **Stop working mode** Keep pressing the button until the monitor does not display numbers ( long press more than 4s) and release the button. LED lights and module shuts down. The output voltage is zero. At this time, it does not perform memory function. ON / OFF output high level (3.3V), then the static power consumption is about 2mA. Click the button, the module starts working again.
