Overvoltage, overcurrent, leakage, insulation fault, high temperature, emergency stop, and door-lock linkage power-off protection.
Core Functions
Safety Protection: Overvoltage, overcurrent, leakage, insulation fault, high temperature, emergency stop, and door-lock linkage power-off protection.
Communication Interaction: Supports RS485 and CAN bus, connects to cloud platforms for QR-code billing, remote operation and maintenance, data upload, and fault alarm.
Multi-Channel Control: Multi-charging-gun time-sharing or simultaneous charging scheduling, pre-charge circuit control, cooling fan control, and contactor sequence driving.
Supported Number of Charging Guns: 1 channel / 2 channels / 4 channels.
Billing Linkage: Supports card swiping, QR-code scanning, offline billing, rate setting, and power current limiting.
