Capabilities of the module with basic settings

This tiny module may surprise you with many important and interesting functions. PS4IoT_V1 with basic settings provides:

• Automatic online switching "battery-mains" and vice versa, without interruption of output voltage generation (12V, 5V, 3V3) of loads;
• Automatically switches to AC/DC adapter 5V when the battery is disconnected without interrupting power to the loads;
• Automatic battery charge/discharge control. Default charge current is set to 0.5 A. The state of the battery charging process is displayed by two LED indicators.

Module application profiles

The module can provide the following profiles for autonomous and controlled use as part of a smart device:

• a battery-free device powered only by an AC/DC 5V adapter;
• a device powered by Li-Ion battery and AC/DC adapter 5V
• a device with a rechargeable Li-Ion battery only;
• a device with fault-tolerant redundancy of 3 power supply paths.

Smart power supply module formula

Online Uninterruptible Power Supply Unit module

• With automatic charger and selectable power source;
• Intelligent and connected;
• With power source redundancy layout;
• Fully autonomous or sufficiently managed;
• With or without a battery;
• For pockets or stationary;
• With simultaneous charging and power supply of load;
• Indoor or outdoor;

Software monitoring of Li-Ion battery charging status

PS4IoT_V1 has a number of signal lines that allow the main controller to monitor the charging process status, temperature, and battery voltage programmatically.

For example, if a mismatch is detected, such as exceeding the charging time or battery temperature, the controller can programmatically stop or restore the charging...
