സജ്ജീകരണ നിർദ്ദേശങ്ങൾ
Follow these steps to set up your UMLIFE charger board:
- കണക്ഷൻ പോയിന്റുകൾ തിരിച്ചറിയുക: Locate the IN+, IN-, B+, B-, OUT+, and OUT- pads on the charger board.
ചിത്രം: മുകളിൽ നിന്ന് താഴേക്ക് view of the charger board. This image clearly shows the input (IN+, IN-), battery (B+, B-), and output (OUT+, OUT-) connection points, which are crucial for proper wiring.
- ബാറ്ററി ബന്ധിപ്പിക്കുക: Connect your 3.7V lithium battery to the B+ and B- pads. Ensure correct polarity: B+ to the positive terminal of the battery, and B- to the negative terminal.
- Connect Load (Optional): If you intend to power a device directly from the charger board while charging, connect your load to the OUT+ and OUT- pads. Note that the "Battery+" and "Output+" terminals are electrically bonded together. The "Output-" and "Battery-" terminals are electrically isolated.
- പവർ സപ്ലൈ ബന്ധിപ്പിക്കുക: Insert a USB Type-C cable into the board's Type-C port. Connect the other end of the cable to a 5V to 6V USB power source, such as a mobile phone charger or a compatible PD fast charging head.
- Activate Protection Board: For the first use, it is necessary to connect the power supply to activate the integrated protection board.
പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once connected, the charger board will begin charging the lithium battery. Observe the LED indicators for charge status:
- ചാർജിംഗ് സൂചകം: A red LED typically indicates that the battery is currently charging.
- Charged Indicator: A green or blue LED typically indicates that the battery is fully charged.
Charging Cycle Behavior:
- The charging cycle automatically terminates when the charging current drops to 100mA after reaching the final float voltagഇ (4.2V).
- ബാറ്ററി വോള്യം ആണെങ്കിൽtage drops below 4.05V (approximately 80% to 90% of capacity), the charging cycle will automatically restart.
- For batteries with voltage below 2.9V, the board initiates a pre-charge phase with a current of 100mA.
സംരക്ഷണ സവിശേഷതകൾ:
The board includes an integrated protection circuit to safeguard the battery and the module:
- ഓവർ-വോളിയംtagഇ സംരക്ഷണം: ബാറ്ററി സുരക്ഷിതമായ വോള്യത്തിനപ്പുറം ചാർജ് ചെയ്യുന്നത് തടയുന്നുtagഇ പരിധി.
- അമിത ഡിസ്ചാർജ് സംരക്ഷണം: Prevents the battery from discharging below 2.4V, extending battery life.
- ഓവർ-കറൻ്റ് പരിരക്ഷ: Limits the output current to 4A to prevent damage from excessive load.
മെയിൻ്റനൻസ്
To ensure the longevity and proper functioning of your charger board:
- Keep the board clean and free from dust and debris.
- Avoid exposing the board to moisture or extreme temperatures.
- ഷോർട്ട് സർക്യൂട്ടുകൾ തടയുന്നതിന് എല്ലാ കണക്ഷനുകളും സുരക്ഷിതമാണെന്നും ശരിയായി ഇൻസുലേറ്റ് ചെയ്തിട്ടുണ്ടെന്നും ഉറപ്പാക്കുക.
