Product Features

1.Safety

The application of new technologies such as active PFC and LLC; Reliable hardware protection and self-checking protection for voltage and current; A perfect charging strategy ensures a highly safe and reliable charging process.

2.Reliable

The shell adopts an aluminum alloy shell structure. With fan cooling, highly reliable product engineering design and years of industry verification, the charger can adapt to harsh usage environments.

3.Intelligent

Supports RS485 or CAN bus interfaces, and communication protocols can be customized to meet the charging needs of customers in various occasions.

Protective Function

1.Overheat protection

When the internal temperature of the charger exceeds the internal set value, the charging current automatically decreases. When the temperature recovers, it will automatically resume charging.

Battery reverse connection protection: When the battery is connected in reverse, the internal circuit of the charger is disconnected from the battery, which will not damage the charger.

2.No-load protection

No output when the battery is not connected.

Short-circuit protection：When an output short circuit occurs, the internal circuit of the charger is disconnected from the battery. Charging can only be resumed after the fault is eliminated and the battery is reconnected.

3.Automatic shutdown when fully charged

When fully charged, the charger automatically turns on the light and turns off the output.
