QC3.0/2.0 Quick charge protocol triggers automatic detection of multiple quick charge protocols:


Five-fold intelligent protection, safe charging and double safety:
According to their actual needs, the user can set the full power-off switch, full power-off parameter conditions, timing charging time, and over-current, over-voltage, low-voltage and other parameters, so that this equipment can be fully automated and unattended according to your needs. The set parameters run automatically, and the real-time monitoring well automatically cuts off the power according to the corresponding settings to protect your charging equipment in all aspects. From then on, your charging becomes more safe, interesting and playable!
1. FCOP: Full power Cut off (ON/OFF), you can set it yourself when the power is < 1W for 1 minute, it will power cut off
2. TC: Timed charging (ON/OFF), you can set the time period of 01:00-24:00 to charge regularly, when it reaches the setting, it will automatically power cut off
3. Over-current protection: you can set the range of 0.0A-5.1A by yourself
4. Over voltage protection: 01V-36V range can be set by yourself
5. Low voltage protection: 00V-35V range can be set by yourself

360° rotating screen on all sides satisfies reading at any angle

UD24 line resistance measurement function for Android/Type-C cable resistance detection
- According to the connection method shown below, first measure the current battery no-load voltage, and then add the output load. At this time, you can read the current battery internal resistance
- The internal resistance calculation formula of this table: (no-load voltage-loaded voltage) / current current = battery internal resistance


USB and Type-C Test Application Range:
- Connect and test various USB and Type-C interfaces and various battery devices
- Multi-port design-multi-use and multi-play

Battery power percentage:
- This meter can freely set the corresponding full voltage value and the lowest value of the discharged voltage according to the battery type in the background by the user. After the system calculates the percentage according to the threshold set by the user, it will display the percentage discoloration through the battery symbol (when it is greater than 30%, it will display green; when it is less than 30%, it shows yellow; when it is less than 10%, it shows red).
- When the display range is between 1% and 100%, the red light of POWER on the panel lights up, and the relay output interface outputs a high level at this time to control the relay to connect the current path. When it exceeds the range of 1%~100%, the red light goes out and the relay outputs a low level to disconnect the current path, so as to ensure the safety protection of charging and discharging of the battery, avoid the risk of damage to the battery due to overcharging and over-discharging, and can also be used for other purposes of over-voltage and low voltage disconnection protection.


Battery internal resistance detection function
- According to the connection method shown below, first measure the current battery no-load voltage, and then add the output load. At this time, you can read the current battery internal resistance.
- The internal resistance calculation formula of this table: (no-load voltage-loaded voltage) / current current = battery internal resistance


DC Power Supply Test Application Range:
- Connect and test various DC power supplies and equipment
- Multi-portion design, one thing, multi-use, multiple play
