500V 300A Coulomb Meter DC Voltage and Current Meter VAC8910F with 3.5" Screen without Bluetooth

500V 300A Coulomb Meter DC Voltage and Current Meter VAC8910F with 3.5" Screen without Bluetooth

Description:
VAC8910F is a multi-function meter. It can display various physical parameters in real time, such as voltage, current, power capacity, energy, temperature, and operating time. Battery charging and discharging management, over-voltage, under-voltage, and over-current protection can be realized separately through its reserved two relay interfaces, accompanied by a buzzer alarm. And the instrument uses a 3.5-inch color LCD as a display. It displays data in a more comprehensive and clear fashion. The device has reserved communication interface for secondary development.

Features:
- 3.5" HD full-color display is clear and shocking
- Wiring is easier and more convenient to use
- The non-contact detection of current is realized by using a Hall sensor. Safe and reliable without disconnecting wires
- Charging and discharging dual relay interface. Five relay working modes can realize automatic opening and closing of charging and discharging
- With charge over-voltage, discharge under-voltage, charge over-current, discharge over-current protection, and buzzer alarm
- Chinese and English selection. Two display colors can be switched and two display interfaces can be adjusted, meeting your various needs
- Optional functions: Bluetooth, temperature measurement, CAN communication, 485 communication, to meet various communication application scenarios
