Product Characteristics

Intelligent  Safe  Efficient 

●High Power Factor: (APFC) Active power factor correction is used in AC input. The power factor is more than 0.98 to achieve green grid.

●High Efficiency: LLC resonant soft-switching technology is used in the charger to achieve the efficiency of 92.0% at full load. It produces little heat and has high reliability.

● It charges lead-acid batteries intelligently. Microprocessors  are  built in the chargers. They judge the battery relative capacity and and identify the ambient temperature in charging process. There will be corresponding charging curves according to the relative capacity of the battery and ambient temperature. The constant current will control in the whole charging proces. It does good to the balance of batteries and extends the battery life

● The technology of circuit board face-down : The circuit board inside th charger is face-down, which avoids dust and foreign material, and reduces failure rate.

AC Input

●AC Input Voltage Range: 187VAC-264VAC ,45-65HZ
●AC Input Current: ≤ 15A

●Power Factor: ≥0.98
●Efficiency: ≥ 92.0%
●Noise: ≤ 50dB

Size and Weight

Net weight:4.8kg

Temperature

Working Temperature :-30℃-55℃

Storage Temperature:-40℃-80℃

Protection Functions

●Overheat protection: when the internal temperature inside the charger exceeds 80 ℃, the charging current automatically reduces. When it is over 87 ℃, the charger shuts down for protection. When the temperature falls, the charger automatically resumes to charge.

●Protection for Reverse Connection of Batteries: The circuit inside the charger shuts down with batteries when the batteries are connected reversely and will not damage the charger

● No-load Protection: There is no output when the batteries are not connected.

● Short Circuit Protection: The circuit inside the charger shuts down with batteries when output is short circuit . The charger will start charging only after troubleshooting and restart the charger.

●  Automatic shutdown when fully charging : The charger automatically turns off after the battery is fully charged according to the charger’s judgement.
