Feature: 1. Safe Operation: The Hall sensor is adopted to collect current, no need to disconnect the wire, and the wiring is convenient and safe. 2. Avoid Complicated Wire Connection: Wireless signal communication is used between the product display and the measuring box to avoid cumbersome wiring. 3. Automatical Management: The measurement box is equipped with a charging and a discharging relay control interfaces, which can realize overvoltage, overcurrent, undervoltage, overtemperature protection, flexibly control charging and discharging, and realize the function of automatic management of charging and discharging. 4. Buzzer Alarm: The product measuring box is equipped with a buzzer alarm function, which can realize overvoltage, overcurrent, undervoltage and overtemperature alarm functions. 5. Widely Used: You can choose for Bluetooth function, temperature function, CAN communication function, 485 communication function to meet various communication application scenarios. Specification: Item Type: Wireless Voltage Ammeter Mode: VAC8910S Material: ABS, PCB Measuring Range: Capacity: 0.001-99999.999AH Energy: 0.001-9999.999KWH Time: 0-100 hours Power Value: 999KW Temperature: 1-150℃ Accuracy: Voltage: ±(1%+2) Words Current: ±(1%+5) Words Temperature: ±2℃ Measurement Rate: 10 Times Per Second Type and Scope of Protection: OVP: 0.01-500v LVP: 0.01-500v OCP: 0-1000A NCP: 0-1000A OTP: 0-100℃ Features: 1. "BAT" battery capacity value setting, this parameter is to set the total battery capacity measured. 2. "BPC" is the percentage of the remaining capacity of the battery, and the remaining AH number of the battery can be set according to this value. 3. "OPP" sets the overpower protection value. If the OPP value is set, when the actual output power value is greater than the set value, it will prompt overpower and cut off the relay (self configured). 4. "OVP" sets the overvoltage protection value. If the OVP value is set, when the actual measured voltage value is greater than the set value, it will prompt overvoltage and cut off the relay (self configured). 5. "LVP" sets the overvoltage protection value. If the LVP value is set, when the actual measured voltage value is less than the set value, it will prompt undervoltage and cut off the relay (self configured). 6. "NCP" sets the overvoltage protection value. If the NCP value is set, when the actual measured charging current value is less than the set value, it will prompt overcurrent and cut off the relay (self configured). 7. "OCP" sets the overvoltage protection value. If the OCP value is set, when the actual measured discharge current value is less than the set value, it will prompt overcurrent and cut off the relay (self configured). 8. "OTP" sets the over temperature protection value. If the OTP value is set, when the actual measured temperature value is greater than the set value, it will prompt over temperature and cut off the relay (self configured). 9. "ADS" communication address code setting. When multi machine communication is different, multi machine communication can be realized by setting the address code. 10. The default relay output state of the "TTL" instrument when it is powered on is normally open or normally closed. 11. "CLR" no load current clearing function, if the actual no load current is not 0, use this function to clear the no load current..
