- Description
Features:
- 1. Wireless transmission of data to avoid interference caused by complex wiring between the display and the detection module;
- 2. The Hall sensor is used to realize non-contact detection of current, without breaking the line, safe, reliable, and convenient;
- 3. Voltage, current, power, temperature (optional), capacity, percentage of remaining capacity, and running time are displayed at the same time;
- 4. Charge and discharge double relay interface, 5 relay working modes can realize automatic disconnection and automatic closing of charge and discharge;
- 5. With charge overvoltage, discharge undervoltage, charge overcurrent, and discharge overcurrent protection, with buzzer alarm prompt function;
- 6. With the power-off memory function, it can record the number of AH and WH before power-off;
- 7. When charging, the percentage progress bar is switched to the color running water light display, and the display screen shows the breathing light flashing effect, which enhances the prompt;
- 8. With voltage, current, and temperature waveform curve display function;
- 9. Comes with TTL serial communication function, which is convenient for secondary development;
Introduction to instruments
VAC8810F is a multi-function instrument based on 2.4G wireless data transmission technology, which can display various physical parameters such as voltage, current, power, capacity, energy, temperature, running time, etc. in real-time. Battery charge and discharge management and over-voltage, under-voltage, and over-current protection are accompanied by a buzzer alarm. Moreover, the instrument uses a 2.4-inch color LCD as a display, which displays more comprehensive, clear, and easy-to-observe data. A communication interface is reserved for secondary development.
Attention and maintenance:
1. Do not exceed the voltage and current range of the instrument, otherwise, the instrument will be damaged.
2. The positive and negative poles cannot be reversed, and the reversed connection cannot be correctly measured.
3. The working temperature is -10~50℃, the storage temperature is -20~70℃, and the instrument is kept in a dry environment.
4. Do not attempt to disassemble the instrument. Damage to the package will void the warranty.
5. When the instrument is working normally, please do not move the instrument violently to avoid irreparable damage to the internal circuit.

(1) Description of self-power supply wiring
Note: If the voltage range of the battery (power supply) under test is between (8-120V) during normal operation, you can use its own power supply wiring method, first adjust the jumper cap of the power supply selection interface to "2W", and connect the battery The positive and negative poles of (power supply) are connected to the voltage measurement port "+Bat-"; note that "+" is connected to the positive pole of the battery (power supply), "-" is connected to the negative pole of the battery (power supply), and the positive and negative poles of the power supply should not be connected incorrectly Or the reverse connection, connect the positive pole of the battery (power supply) to the positive pole of the load, and the negative pole of the battery (power supply) to the negative pole of the load through the Hall sensor. When the direction of the working current is consistent with the direction of the arrow on the Hall sensor, the measured current will It is displayed as a positive value, otherwise the measured current is displayed as a negative value.
(2) Description of external power supply wiring
Note: If the voltage range of the battery (power supply) under test is not between (8-120V) during normal operation, the external power supply wiring method can be used. First, adjust the jumper cap of the power supply selection interface to "3W", and set the external power supply The positive and negative poles are connected to "+Vext-", note that "+" is connected to the positive pole of the external power supply, and "-" is connected to the negative pole of the external power supply; then when wiring, connect the positive and negative poles of the battery (power supply) to the voltage measurement port "+Bat" -", note that "+" is connected to the positive pole of the battery (power supply), and "-" is connected to the negative pole of the battery (power supply). Do not connect the positive and negative poles of the battery (power supply) wrongly or reversely, connect the positive pole of the battery (power supply) to the positive pole of the load, and the negative pole of the battery (power supply) to the negative pole of the load through the Hall sensor. When the arrows on the sensor are in the same direction, the measured current will be displayed as a positive value, otherwise, the measured current will be displayed as a negative value.
(3)Wiring instructions of the charging relay
Note: The working power of the relay is provided by an external power supply. If the relay is connected, an external power supply with the same working voltage as the relay should be provided. Connect the control port of the relay to the interface of the charging controller. If you want to control the positive pole of the charging, pass the positive wire through the relay. If you want to control the negative pole of the charging, connect the negative wire to the relay. When the relay is closed, the "IN" light will light up and turn off as a reminder when disconnected.
(4)Discharge relay wiring instructions
Note: The working power of the relay is provided by an external power supply. If the relay is connected, an external power supply with the same working voltage as the relay should be provided. Connect the control port of the relay to the discharge controller interface. If you want to control the positive pole of the discharge, pass the positive wire through the relay. If you want to control the negative pole of the discharge, connect the negative wire to the relay. When the relay is closed, the "OUT" light will light up and turn off as a reminder when disconnected.
