12V to 48V Driving Charge
The 3KW charger model provides powerful bidirectional energy transfer from a 12V generator to a 48V auxiliary battery, making it ideal for large vehicles with higher energy demands during driving operations.
48V to 12V Emergency Charge
In emergencies, the 3KW charger reverses the energy flow to charge the 12V vehicle battery from the 48V auxiliary battery. This ensures reliable performance and operation when the 12V battery is depleted, particularly in heavy-duty vehicles.
High-Precision Voltage Control
The 3KW model operates with a voltage range of 50V to 100V on the 48V side and offers precise control over the current, ensuring safe and efficient energy management. This model is designed for vehicles with higher power needs.
High-Efficiency Fast Charging
Supporting up to 90A on the 12V side and 80A on the 48V side, the 3KW charger enables rapid charging of both the 48V auxiliary battery and the 12V vehicle battery. This feature ensures high efficiency in large-scale operations.
Comprehensive Protection Features
With an IP68 rating, the 3KW charger is dustproof, shockproof, and includes protection against overcurrent, overcharging, over-discharging, and temperature extremes, ensuring reliable operation even in the harshest environments.
Durable Heat Management
This model features a large-area heat sink for natural cooling, eliminating the need for a fan. This cooling method ensures high durability and reduces the risk of overheating during extended use in heavy-duty applications.
MODBUS Communication
The 3KW charger supports MODBUS communication, allowing for remote monitoring and configuration. Users can set parameters and check the system status via a 10-inch LCD display or smartphone, enhancing control and usability.
Flexible Installation Options
The 3KW model allows for multi-position installation, offering flexibility in mounting and positioning within various vehicle types. This versatility ensures that the charger can be adapted to different operational needs.
Compact and Portable
With dimensions of 265mm x 210mm x 105mm and a weight of 2.5kg, the 3KW model combines powerful performance with a compact, space-efficient design, making it suitable for vehicles with high energy consumption.
