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. Overcurrent 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 Support 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 devicesMulti-port

design-multi-use and multi-play!

Battery power percentage

The meter can freely set the battery type according to the user in the background, the
corresponding full voltage value and discharge voltage

If there is no low value, the system calculates the percentage according to the threshold set by the
user, and then changes the color of the percentage through the battery symbol

Display (more than 30% green, less than 30% yellow, less than 10% red);

When the display range is between 1% and 100%, the POWER red light on the panel lights up, and
the relay output interface outputs at this time

The level is used to control the relay to connect the current path. When it exceeds the range of
1%~100%, the red light goes out at the same time

The plug electric appliance outputs a low level to disconnect the current path to ensure the safety
protection of the battery for charging and discharging.

People avoid the risk of damaging the battery due to overcharge and overdischarge, and it can also
be used for other purposes of overvoltage and low voltage disconnect 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
