12V to 48V Driving Charge
The 2KW model allows for a seamless driving charge from a 12V generator to a 48V auxiliary battery, ensuring smooth energy transfer while driving, with enhanced charging capabilities suited for medium-duty vehicles.
48V to 12V Emergency Charge
In emergency situations, the 2KW charger provides reverse energy flow, charging the 12V original vehicle battery from the 48V auxiliary battery, ensuring the vehicle remains operational when the main battery is depleted.
Intelligent Current Management
With an input voltage range of 50V to 100V and up to 80A current on the 48V generator side, the 2KW charger offers precise control over current and voltage through its integrated microprocessor, preventing overcharging and enhancing safety.
High-Efficiency Fast Charging
This model supports fast charging with up to 80A current for both the 48V and 12V sides, ensuring rapid power replenishment during operation, suitable for vehicles requiring higher energy capacities.
Advanced Temperature Protection
The 2KW charger includes a fan that activates when temperatures exceed 40°C and shuts down when it reaches 80°C, automatically resuming operation below 60°C. This feature enhances the charger’s reliability in extreme conditions.
Durable Heat Management
The charger is equipped with a large heat sink for natural cooling, ensuring efficient heat dissipation without the need for a fan, which extends the lifespan of the charger by minimizing wear and tear.
MODBUS Communication
The 2KW model features MODBUS communication for simplified wiring and system monitoring, allowing for remote access and configuration of the charger’s operating modes and parameters via a smartphone or a 10-inch LCD display.
Flexible Installation Options
The 2KW charger supports various installation positions, making it adaptable for a wide range of vehicles. This flexibility simplifies integration, providing users with more options for placement.
Compact and Portable
With the same dimensions as the 1KW model (265mm x 210mm x 105mm) but a slightly higher weight of 2.4kg, the 2KW model is still highly portable and space-efficient, delivering powerful performance in a compact form factor.
